[Talk-de] Androhung von Benutzersperren für Verklebe-Ideologie

2018-10-19 Thread Frederik Ramm
Hallo,

leider kommt es immer wieder zu Changeset-Diskussionen wie hier:

https://www.openstreetmap.org/changeset/63602349

Irgendein Neuling mappt irgendwas mit "zusammengeklebten" Flächen,
irgendeiner meckert dran rum, dann kommen flohoff und OF0 und hauen noch
obendrauf, weil sie ihren privaten Kreuzzug führen, und zurück bleibt
ein Neuling mit einem Riesen-Fragezeichen im Gesicht, der gar nicht
versteht, was er da ausgelöst hat.

Das ist nicht gut. Wenn diese Debatte nicht projektweit oder wenigstens
deutschlandweit vernünftig geführt und das Problem nicht gelöst werden
kann, dann sollte man auch nicht versuchen, "seine" Ansicht ungefragt
armen Newbies aufs Auge zu drücken, nach dem Motto, die können sich ja
nicht wehren.

Ich werde Benutzer, die sich in solche Changeset-Diskussionen
verzetteln, künftig deswegen sperren.

Ich würde jetzt keinen Feldzug starten und diese Tags löschen, aber wenn
ich so eine Grenze anfasse und editiere, würde ich sie am Ende nur noch
mit einem boundary=administrative, maximal einem admin_level ausstatten
und in die richtigen Relationen einsortieren.

In der Vergangenheit gab es immer mal wieder Mapper, die diese Namen
gesetzt haben, weil es ihnen die Qualitätskontrolle erleichtert. Früher

[OSM-talk] "Travel like a KLocal" series of printed maps

Hi,

someone has written to DWG because they were disappointed with a "Travel
like a Local" map they bought on Amazon. Apparently there's an author
there named "Maxwell Fox" who churns out these "Books" which promise,
among other things:

"The map is very detailed and it will not only give you all the
available roads and routes, but also the essential information to make
your Luxembourg City (Luxembourg) vacation unforgettable."

"In the map you can see all the available means of transport, bus stops
and routes so you can always know how to get everywhere."

"And because we know that a vacation is not only about the roads and
busses, the map gives you many options for eating, drinking and having a
good time!"

"We carefully marked all the restaurants, bars and pubs so you can
always find one that is nearby."

"In the Luxembourg City (Luxembourg) map you will also find the best
places to go shopping, the most famous and must-see sights, churches and
more."

"And if an emergency comes up, there are markings of police stations and
hospitals everywhere for your convenience."

"Each kind of marking has a different color so you can easily navigate
around the map and find exactly what you’re looking for within seconds."

Is this a new phenomenon? Has anyone seen any of these maps, or seen a
report about them? The Amazon listing doesn't say the data comes from
OSM, but I guess the printed work must, otherwise the complainant would
not have written to us...

Someone attempted to re-develop JOSM (as "JOSM-ng") in 2008 and even

it was written is irrelevant and that it could probably rewritten if
need be. But this was an opinion not widely shared among other

Writing a new piece of software that fully mimicks an existing program
is likely to be easier than developing a new editor from scratch, but
it's still a lot of work, and I don't currently see the need. I guess
there will be workarounds for many of the issues you mention, and some
issues are not work-around-able - for example, if your IT admin decides
that you should not be able to install software locally for security
reasons, then it is hard to envisage any kind of "offline editor"
working well. C# won't save you here.

Well, "strongest possible terms" is perhaps not the most fitting summary
of https://github.com/openstreetmap/osm2pgsql/issues/230... as has been
said there, quite a few people "mis"use osm2pgsql in that fashion, and
if they ever were to introduce a breaking change you can simply stick
with the osm2pgsql that you have...

But answering your question about alternatives:

* I have successfully used imposm3 to populate planet-wide databases and
keep them current with diffs, and the overall performance was sligthly
better than osm2pgsql's (with imposm having some features that osm2pgsql
doesn't and vice versa), but what osm2pgsql does with its
planet_osm_rels table imposm does with a file-based database and I have
no idea how difficult it would be to establish your first-class relation
table.

* The "PG Snapshot" schema used by Osmosis provides an interesting
concept of an "action" table which is filled upon the application of a
diff and allows you to run arbitrary code on newly-added or modified
things in the course of an update. The performance of Osmosis is,
however, far worse than osm2pgsql or imposm in my experience, and the PG
Snapshot schema is probably much too close to "raw OSM" for a mainly
rendering use case.

* If I wanted to achieve what you describe, I would likely either modify
osm2pgsql to do what I want, or run stock osm2pgsql and devise a
*separate* process, likely based on (py)osmium, that extracts the
information I need from a planet file or diff, and somehow adds that to
my PostGIS database. That way, I would continue to be able to use
osm2pgsql for what it does best, and I could still add my special
processing on top. Since my special processing is likely to only need a
fraction of the data, and osmium is quite efficient at filtering, the
risk of running into performance issues should be limited.

I would like to recommend that you don't use the term "quality
monitoring tool" for this since you're measuring quantity not quality.
At best, I'd call it a tool that monitors "richness" or "completeness".

Simply counting how many features there are and how many of a
pre-defined list of tags each one has shouldn't be called "quality
monitoring", because there will be situations where the OpenStreetMap
community requests of project managers (who your web site claims to be
targeted at) that they implement some form of quality assurance; calling
your statistics tool a "quality monitoring" tool runs the risk of making
these people believe that quality requirements can be fulfilled by
ensuring that enough tags are set, which is definitely not what the
wider community would regard as a suitable quality assurance for a
humanitarian data entry project.

I know Perl isn't what people use these days but just to show that it
really isn't rocket science (and doesn't require elaborate routing
engines for that scale) I've made a modified version of the Perl script
and checked it into the SVN directory. That script will take a .osm data
file as input and generate a schematic map like

http://www.remote.org/frederik/tmp/ipswich-busstops.png

(which depicts Ipswich), where nodes are coloured according to their
distance from the nearest bus stop (in this picture, 500 Mercator metres
or more means something gets red).

And even more cities have their bus stops mapped in the traditional
fashion, like, riding a bus and recording where it stops. It's amazing

Many standard routing tools (Graphhopper, OSRM, Valhalla) can do
"isochrones", that is essentially what you are looking for for one
single bus stop. You would simply run that for every bus stop and join
the results together.

Since you don't need instant results and you don't want to run this for
a whole country, the algorithm to use is really simple - build a routing
graph, annotate each bus stop node with a travel time of "0", and travel
outwards along all reachable nodes, increasing your travel time by the
time it takes to walk the edge you are using, until you reach a node
that already has a smaller time annotation than you have accumulated.

There's a simple Perl implementation in
svn.openstreetmap.org/applications/utils/distance_maps that could be
used as a basis if Perl is your thing but you could use pg_routing just
as well.

Having said that:

1. In the concrete example of a hospital, I would expect the local bus
operator to create a new bus stop or even change a bus route to
accommodate the hospital. Of course this would not work if you wanted to
set up a bakery.

2. The existence of a bus stop in OSM does not mean it is actually
served by a route; and the existence of a route in OSM that serves the
bus stop does not necessarily say what frequency - it could be the
school bus that only goes three times a day, or the night bus, or the
bus extension to the pool that only goes in summer.

> From 1974 to 1997, the county of Rutland didn't exist.

It's nice to see such a passionate plea for one particular historic
boundary, and pleas like that are what can give rise to the exceptions I
was talking about.

These exceptions do not, however, mean that it's a free-for-all for all
kinds of historic boundaries. I don't know about Rutland - the way you
say it sounds as if it is, and has always been, crystal clear what is
part of Rutland and what is not. But one participant in this thread has
stated that their particular county boundary has changed many times over
the years. I don't know if the people inhabiting the areas that have
changed hands each time kept a stubborn affection for "their *real*
county" just as you describe the people of Rutland to have done. For the
sake of the argument, let's assume there had been a couple of minor
changes to the boundary of "Rutland County Council District Council"
since 1997. Surely your argument which seems to be based on the romantic
"Rutland that people feel in their hearts" could not be applied as a
reason to store "Rutland County Council District Council in the borders
of 1997", plus "Rutland County Council District Council in the borders
of 1999", and also "Rutland County Council District Council in the
borders of 2003"...?

A line needs to be drawn, because otherwise there *will* be people
mapping these things ("for historic interest"), and they won't stop at
historic administrative boundaries; they will include electoral wards of
all EU elections back to god knows when, parish boundaries from 1905,
and school districts for good measure. And each time it will become more
different to maintain the data. How is someone who moves a river to be
more in line with current aerial imagery supposed to know which of the
23 boundaries using that river should be affected and which not?

All the reasons you have listed were based on popular use. You said
things like "pretty much everyone put their address as ...", "no-one
thinks they live in ..." etc.; at the same time such things are often
not very precise and don't easily lend themselves to drawing boundaries.
The "West Hampstead" you mention is mapped as a point - perhaps
precisely because it has no documented administrative boundary to go
with it but is a "property speculator's construct" as you say?

I think that if case-by-case exceptions are made from our "verifiable on
the ground" rule, then at the very least the object in question must be
important enough (an admin boundary that 30.000 people believe to live
in would qualify, an electoral ward that was abolished in 1905 and is
only remembered by those of the age 120+, not so much), and if someone
wants to map it as a relation (which cannot be done in a fuzzy way) then
it must be sufficiently clear where the boundary is because else we'll
have 10 mappers edit-warring over if a certain address still belongs to
the posh neighbourhood of Silver Springs or to its seedy neighbour,
Golden Showers.

You shouldn't, it is one of our basic principles and it's here to stay.
Usually people don't say "current or real" but "verifiable on the
ground". The fundamental idea goes like this: If two mappers disagree
about a feature, they can simply go there and the conflict can be solved
immediately.

Allowing stuff that is not verifiable on the ground would rob us of this
possibility - all of a sudden we'd have to meet in libraries or
courthouses or universities to find out who's right.

We don't want that, generally.

But we are not fundamentalists, and we do allow exceptions. One obvious
exception is current administrative boundaries; they are not easily
verifiable on the ground but we're making an exception because of their
undoubted usefulness.

In addition these generally accepted exceptions, there's also a lot of
stuff in our database that will not withstand scrutiny and will likely
be deleted if someone looks at it with a keen "is this verifiable on the
ground" eye. The existence of such data cannot be taken as a sign that
our principles are moot.

All this is true, and simple regular expression matching will never fix
things (the village of Fucking in Austria is a well-known example but
the number of names that are legit in one language and offensive in
another is high).

If you prohibit me from changing the name of New York to "Jewtropolis",
I'll just create a city node one block away from it with a slightly
higher population, causing it to be rendered with priority.

If you start down this road, you will end up not using OSM place names
at all but instead relying on a curated data set like Natural Earth,
which is a valid decision to make for a cartographer but means taking
control away from mappers and giving it to a hand-picked circle of data
curators.

> At very least, you can force your vandals to be clever to succeed.

But is this really what we want - ever more clever vandalism that is
ever less likely to be detected? Is it not even *better* to have
"obvious" vandalism that we can fix easily? Today, getting "Jewtropolis"
written large across OSM for an hour or two is no big deal, nothing to
brag about before your cool hacker friends. "So what" is the answer. Do
we want to make this into a trophy? Today, the headline is "some asshole
put 'Jewtropolis' on OSM" - tomorrow, "clever hacker penetrates OSM
defences"?

It is ok for a data consumer to do that. Nobody is hurt if your filters
wrongly reject a valid contribution in Africa. It would also be ok to
build something that prioritizes things for review. But trying to build
some kind of "protection" into the data ingestion at OSM would

* impact performance negatively
* disenfranchise mappers
* bind resources for the constant maintenance of block lists
* encourage clever(er) vandalism

and hence not be worth it.

We can only speculate about the motives here - frankly my money is on
"attention seeking teenager" who could just as well have labelled a city
the "Weed Capital". Which would not have been hate speech and maybe not
reported as widely, but not really any better.

Some have, some not; the English Wikipedia, for example, has not, while
the German Wikipedia has, to a degree.

A move like this would have to be very carefully considered as it binds
resources and reduces our ability to attract new mappers (a certain
percentage of whom would not make that first hurdle).

It is also a technical challenge: If the new signup creates a new
object, and before this is reviewed someone else creates the same new
object, what happens? If the new signup modifies an object and before
the modification is reviewed someone else modifies a different object in
a way hat would make both edits clash (e.g. buildings overlap), what
happens? If we don't attract enough reviewers and new edits remain
unpublished for days or even weeks...?

Reducing the possible participation envelope of new mappers is certainly
something that can be discussed, but it's not something we should do on
a whim, and certainly not to please unspecified and scared "Powers That
Be". Perhaps educating our users about the strengths and weaknesses of
crowd-sourcing is another option.

Das stimmt, und auch allein schon der Speicher-Aufwand für die Menge von
Bildern, die Mapillary hat, ist natürlich enorm. Wenn die sagen würden
"hier kann man alle Bilder von Hessen runterladen", zahlen sie
vermutlich jedesmal 5 Euro, wenn jemand den Button drückt oder so. Ich
sehe ein, dass das nicht leicht ist.

Trotzdem - wäre es ein wirklich offenes Projekt, das ein Interesse daran
hat, die gesamelten Daten maximaler Nutzung zuzuführen, dann müsste es
solche Dumps in irgeneiner Form geben, und auch sowas wie "diff
updates", mit der jemand sich eine eigene (Teil-)Sammlung aktuell halten
kann.

Dadurch, dass jeder Zugriff erzwungenermaßen durch deren API erfolgt,
haben sie "den Daumen drauf". Sie können das API jederzeit abschalten -
und was ist dann? Ebenfalls ist es wichtig, zu sehen, dass anders als
z.B. bei Wikipedia oder OpenStreetMap der Uploader Mapillary ein
unbegrenztes Nutzungsrecht einräumt. Wenn sich Mapillary heute
entscheidet (z.B. weil sie aufgekauft werden), dass die Bilder ab sofort
nicht mehr oder nur gegen Zahlung von Lizenzgebühren verfügbar sind,
dann ist das so. Jeder, der heute freiwillig Daten zu Mapillary
hochlädt, erhöht den Wert des Bilderschatzes bei Mapillary, der heute
schon "nur begrenzt frei" ist (weil man ihn nicht komplett bekommt) und
dessen Freiheit jederzeit ohne Angabe von Gründen beendet werden kann.

Aus Sicht von jemandem, dem freies Wissen am Herzen liegt, kann eine
Teilnahme an Mapillary nur dann gerechtfertigt sein, wenn man
kurzfristig Nutzen aus den hochgeladenen Bildern zieht und sie z.B. für
das Mapping bei OSM nutzt. Was man *nicht* tut, ist am Aufbau eines
langfristig offenen Bilderschatzes mitzuarbeiten - langfristig arbeitet
man nur dem Börsenwert eines Unternehmens zu.

Ich will die Teilnahme an Mapillary nicht verteufeln, aber ich finde,
dass gerade Wikimedia mit ihrem Fokus auf "freiem Wissen" hier zumindest
eine kritische Distanz einhalten sollte - ein Beitrag zu OpenStreetMap
oder Wikipedia ist im Sinne von "freiem Wissen" eine ganz andere
Kategorie als ein Beitrag zu Mapillary.

Hallo Nico,

könnte, so dass der FOSSGIS von solchen Plänen nicht erst aus den

Mir stößt ein bisschen negativ auf, dass "Mapillary" (mit Tippfehler)
als Beispiel auf der Seite genannt wird. Mapillary wird zwar von vielen
OSMern gern benutzt und gibt einzelne Bilder über eine API unter der
CC-BY-SA-Lizenz heraus, aber über die Gesamtheit der Bilder kann nur
Mapillary selbst verfügen. Sowas wie "ich lasse mal einen
selbstgebastelten Algorithmus über alle Bilder in Hessen laufen" oder
sowas geht nicht, und wenn Mapillary irgendwann pleite macht oder
aufgekauft wird, sind die Bilder halt weg. Das, finde ich, sollte man
nicht unterstützen - es ist "openwashing".

I think he shouldn't have done this. He should have argued his case here
and the community should have come to an explicit resolution, rather
than one party creating a "status quo".

Personally, I am very much against mapping historic boundaries in OSM,
mostly because the exemption from the "on the ground" rules that apply
to current administrative borders (they are so important that we make an
exception) don't hold for historic boundaries.

But there's a general problem with boundary relations getting out of
hand. Take this little unnamed waterway here

https://www.openstreetmap.org/way/614127384

which is meanwhile a member of 19 different boundary relations:

* South East England European Parliamant Constituency
* The admin_level=8 boundaries New Forest and East Dorset
* New Forest West UK Parliament Constituency (4152802)
* Alderholt Civil Parish and Damerham Civil Parish
* Cranborne Chase & West Wiltshire Downs AONB (2664452)
* Dorset historic county and Wiltshire historic county
* an administrative region called "South West England" and an
administrative region called "South East England", both admin_level 5
* The Hampshire Constabulary boundary ("boundary=police") which exists
twice (relations 3999378, 8188274) if any proof was needed that this is
getting out of hand even for those who added it
* The Hampshire Fire and Rescue Service boundary ("boundary=fire")
* Hampshire County and Dorset County
* Hampshire Ceremonial County and Dorset Ceremonial County
* A statistical boundary called "Hampshire and Isle of Wight"

I have not analyzed these in detail and I won't make an attempt to tell
the readers of this mailing list which of these make sense to have in
your country. But I have a hunch that, say, the statistical boundary
"Hampshire and Isle of Wight" is not actually defined as a boundary. I
have a hunch that if the boundary of Hampshire were to change, then this
statistical area would also change - because it is *not* defined by
geometry, but just by reference to existing administrative boundaries.

I think we should all think twice before duplicating and triplicating
data in OSM just because there's yet another boundary that includes
Hampshire. We should find a way to reference existing boundaries instead
of copying them.

Practically all of the relations above have version numbers in the
hundreds, version numbers that have again increased when smb1001 did his
historic boundary mapping - of course he hasn't changed anything in the
statistical boundary "Hampshire and Isle of Wight" but still he's listed
as last modifier of this relation just because he has just split up a
way that was part of the Hampshire boundary.

I think if we continue heaping ever more boundary relations onto what we
have, we'll make things less and less understandable, less and less
maintainable.

But that's a general remark, not *specificall* aimed at history county
boundaries.

Bye
Frederik

PS: Of course, public transport relations are an even bigger culprit.
There are a handful of ways in OSM in England that are member of more
then 100 relations, mostly bus routes as far as I can see.

If it's a "country" somewhere in the sea then it's relatively easy to
delete, and everyone is encouraged to delete obvious vandalism like that
on sight.

It is always a good idea to add a public comment to the vandalism edits
explaining that the data has been deleted, and why - more often than
not, the "vandal" thought they were just doodling in their private sandbox!

If the task is too daunting for you, you can bring it to the attention
of other mappers who are more experienced - message to the mailing list
is ok, though a synchronous channel like IRC or Slack might yield
quicker results.

There's also the Data Working Group at d...@osmfoundation.org to deal
with matters that the community cannot easily resolve themselves - for
example, if you have a persistent vandal that needs to be blocked from
making further edits.

The edits you highlighted have been reverted by user Carnildo a couple
hours ago.

It appears that of the 177,151 buildings still there, only 29,513 have

Btw I have commented on this changeset. Apparently the main use case is
having a general indication of "there are people living here".

In a way, it's what we did in Western Europe when we only had Landsat
imagery: "Uh, this looks like a settlement, let's draw a grey blob" ;)

I guess it would look less silly if it had been created on a coarser
level. What we have here *suggests* precision due to the many nodes, but
in the end it's relatively random. Like if you specify the result of a
measurement as 4.35375423 when your error is +/- 1 ;)

A little buffering and simplifying would probably have been a sensible
idea. But then again, had they asked beforehand, it's possible that we
would have told them it's a bad idea to start with ;)

[Talk-us] buggy buildings in Maryland

2018-08-16 Thread Frederik Ramm
Hi,

over the last 2 years, DWG has had a three different complaints about a
buggy building import that has been run on and off by the user
"annapolissailor".

The import was problematic in many ways, most obviously because huge
batches of un-used nodes were uploaded and later it was attempted to
connect them, which sometimes failed, leaving lots of un-used nodes in
the database; also, almost all buildings are over-noded, taking 10 or
more nodes for a simple rectangular building (eg
https://www.openstreetmap.org/way/435663194). Buildings that were in the
area before have been deleted outright, and the data source and legal
situation is unclear (many buildings are much too precise to have come
from aerial imagery).

(Needless to say, had the import been discussed up front as is
customary, all these issues could have been avoided.)

I have tried to work with the importer but they seem to be ultimately
unable or unwilling to fix the problems even though they did seem to
understand the issue at some point
(https://www.openstreetmap.org/user_blocks/1587). They asked me a couple
of times to "hold off reverting data until next steps are discussed on
the imports list" but never followed up on the promise. They claimed to
have spent hundreds of hours on the JOSM validator improving problems
they had introduced.

I am at the moment deleting about 70,000 untagged and un-used nodes that
have been left over from this import, which is the uncontroversial part.

The total amount of buildings created and still visible is 177,151, with
a total of 1,980,336 nodes, in the general area "East of Washington DC,
South of Baltimore, North of Chesapeake Beach".

I think these buildings need to be deleted too, given their technical
(over-noding) and legal (we don't know where the data came from and what
license it is under) issues.

However, given how much work the mapper claims to have invested in this,
I wonder if there's maybe a way to salvage the data. That would first
require us to clear up the legal situation, and if it turns out the
source is legal, then we'd have to go about killing the extra nodes in
buildings.

I'm basically looking for volunteers here. Other mappers have tried to
discuss the issue with the mapper himself and never got far either, but
of course if someone wanted to try and enlist annapolissailor's support,
fair enough (perhaps agree here on the list who's doing it though, so
that we don't have 10 people spamming him...)

I have prepared a file that contains all the buildings in question:

Which code would you then add to a building? Who would be given the
power to decide (maybe of the several possible codes, one is nicer or
contains the initials of the owner)? How would it be verifiable which
code a building has?

This is bad, but not as bad as adding them on purpose in the course of

Adding coordinates, or plus codes, as tags to OSM makes no sense.
Building an aid project around it and doing it on purpose is at best
negligent and at worst cynical. It is a waste of the money of whoever
funds the aid project, a waste of resources in OSM, and a waste of time

Christoph was a bit harsh in his response but I think he is right on teh
fundamentals, and I urge you to reconsider.

As I have explained in another post just a few minutes ago, taking the
"adding tags to OSM" approach is a cynical form of aid - it makes people
using it depend on your aid. It wastes effort with those adding the
data, it wastes storage space in OSM, it has *nothing*, absolutely
nothing going for it.

The sensible approach is to add the logic that converts plus codes to
locations and vice versa to those places where people interface with the
map - be that the osm.org web site, or the offline application they're
using, or the machine that prints a map. It would not be difficult to
modify e.g. the humanitarian map style to print plus codes onto
buildings, computing them on the fly, if that's desired. Doing this
means you develop it once and it is immediately usable everywhere by
everyone. That is the only sensible approach. Otherwise you'll be stuck
running one project after the other ("add plus codes for X community",
"add plus codes for Y community", etc.), and not only that: The generic
approach will automatically work for everything built in the future. It
can be used to address not only houses but wells, mountains, bays, even
trees. It is better in *every* respect.

We must let reason prevail here and not do something on a whim based on
a misunderstanding of how things work.

It is sad that it has come to a point where some people seem to have
already built "projects" around importing plus codes in a way that
everyone here would have told them is the least useful of all, had they
botehred to ask! Let us stop the madness before it spreads further, and
work on doing it right.

Re: [OSM-talk] Is it technically and legally possible to add the Open Location Code to the OSM search?

2018-08-10 Thread Frederik Ramm
Hi,

I am very surprised that this discussion is not dead yet. To me, this is
like one person saying 1+1 is 2 and the other person saying 1+1 is 3.
This is something that should not be a matter of opinion; this is a
matter of logic.

Vao, when you write:

> My objective is to give addresses to people who will never have one.

that's totally ok, and can be done with OSM and plus codes, no question!

The issue is just: Should the algorithm that converts lat/lon into plus
codes be applied "centrally" and the result of the computation stored in
OSM (which seems to be your approach), or should the computation instead
happen at the point where a human being interfaces with OSM.

To take the example of OSMAnd and make it very clear, step by step.

Let's assume we have two people, each using OSMAnd, and one person (A)
wants to communicate to the other person (B) where they live.

Your approach goes like this:

1. A zooms to their house on OSMAnd.
2. A clicks on the house to somehow bring up all tags the house has.
3. One of these tags is the plus code, because it has been added at
another time by a third party.
4. A tells B the plus code.
5. B invokes a search function on their OSMAnd, and OSMAnd searches for
an object that has the given plus code.
6. B knows where to go.

This approach requires extra functionality in OSMAnd (namely: evaluating
the plus code tags), and it requires a third party to have added the
plus code for the location in question beforehand. It also requires OSM
to store the plus codes.

The approach that I - and everyone else who applies the same logic -
propose, is:

1. A zooms to their house on OSMAnd.
2. A clicks on the house to invoke the plus code computation function in
OSMAnd.
3. OSMAnd displays the plus code.
4. A tells B the plus code.
5. B enters the plus code into OSMAnd, and OSMAnd applies the reverse
computation function.
6. B knows where to go.

This approach requires extra functionality in OSMAnd to apply the plus
code computation, but libraries and code for that exist. This approach
does NOT require that someone else has added the particular location to
OSM before - it works everywhere on the planet. Also, this approach does
not require OSM to store all the plus codes.

The only thing that approach A has going for it is that if someone has
the means to access OSM, but has no means to invoke the plus code
computation, they can still read the plus code from the tag. But I
struggle to think of a scenario like that.

I think that approach B is not only better, it is the only sane
approach. Approach A makes users dependent on the goodwill of someone
who uploads all the tags to OSM. Approach B makes this "someone"
unnecessary. When used in a humanitarian/development context, approach A
represents the old style of making people dependent on aid (dependent on
a third party running a plus code import project), whereas approach B is
making users independent. Approach A is the wrong approach for everyone.

> It is interesting that this effort for
> addressing is being trashed because it is savvy technology.

You are misreading me and many others here. Plus codes may be savvy
technology (albeit I can see how the dependency on latin alphabet may be
putting some people off). Plus codes themselves are not under attack
here; what is being criticized is using plus codes to do "approach A",
and *that* is very certainly not savvy!

I and many others have said this a few times in this thread, and I have
the impression that it has not really become clear. I hope that this
lengthy post has managed to explain it, and I am sure that once you have
thought this through you will see that - *especially* from a development
aid perspective - approach A is the last thing you want!

There's absolutely nothing to be said against OSMand using plus codes,
indeed, this proves that plus codes can be used perfectly well without
adding them to the OSM database.

I'm not sure I understand what you mean by "remove all tags and convince
everyone to just use lat/long". Our tags describe not *where* something
is, but *what* something is, a feature certainly as useful in Tanzania
as elsewhere. The description of *where* something is does indeed happen
by latitude and longitude in OSM.

In some countries we add street addresses, but only because there's no
mathematical way to derive a lat/long from the address. If it were
possible to apply a formula to an address and arrive at a lat/long, or
apply a formula to a lat/long and arrive at a street address, nobody
would be mapping them.

Just as nobody should be mapping plus codes. Put the formula in the
device (e.g. OSMand) and you have plus code support for the whole
planet. No need to import billions of address points. It's faster,
cleaner, and less likely to break.

This is not a good idea. Please don't do it. It does not make sense! If
someone searches for a plus code on a web site, the site can compute the
lat/lon and take you there, WITHOUT having to add billions of plus code
points all over the word.

I am certainly not a what3words fan (I hope this is obvious) but in the
service of truth I need to say two things for them: First, they claim
that their offline addressing database is actually not huge, but small
enough to use on most devices. The problem is not that the database is
huge, it's that the database is protected and they'll slap a takedown
notice on anyone using it without their agreement, e.g.
https://github.com/github/dmca/blob/master/2016/2016-07-05-what3words.md.

Second, they claim that saying three natural language words on a
potentially low-quality radio or mobile phone connection leaves less
room for misreadings than dictating a string of numbers. They claim that
the dictionary has been curated in a way as to not have similar-sounding
words, a claim that, I believe, has been often ridiculed with examples
but I don't have any at hand right now.

Hi,

I don't necessarily agree with all that's been written but I found

http://journals.sagepub.com/doi/10.1177/2053951718790591

an interesting read: "The social construction of technological stasis:
The stagnating data structure in OpenStreetMap."

Grossly simplified, the author tries to answer the question "why haven't
we shipped API 0.7 yet" from a social science viewpoint.

What made me angry when I saw the edits was not that they were buggy -
anyone starts out making buggy edits and I still make them to this day.
And there's no difference between bumbling US newbies and bumbling
German newbies or anywhere else in the world.

What pisses me off is when bumbling newbiedom goes hand in hand with
bigmouthed web sites about how the so-and-so project is making the world
a better place, and then I look at what the project with the cool "store
front" actually does in OSM and see rubbish. This is not the work of a
student who has just discovered OSM and is taking their first steps.
This is the work of a student who has signed up for a project, and been
instructed by someone who is ultimately part of the group that makes the
cool public-facing web site about OpenSidewalks. And what I see in OSM
is not something that is suitable to achieve the project goals. It
should be in the project's own interest to avoid or repair this.

So my impression is, there's a project here that has invested a
significant part of their time into convincing third parties that
they're doing a great thing (maybe even convincing third parties that
they're worth funding), but they treat OSM with much less diligence than
they spend on their store front. In the end, it seems to be "good
enough" to have students add disjunct lines that are unlikely to ever
achieve any of the goals OpenSidewalks claims to pursue.

If OSM was anything valuable to them, anything worth caring for, and not
just a vehicle to piggyback their project on, then they would provide
better training and supervision to their students so that mistakes like
the ones I randomly stumbled across either do not happen, or are corrected.

This is nothing to do with US mappers in general, I only posted here
because it happens to be a US location. Similar things happen everywhere
(even though some cultures seem more prone to do big PR than others). It
is not even about mappers at all, because it is much more likely that
those enlisting, instructing, and supervising the student are at fault
here than that the student received excellent instructions and just
wasn't up to it.

I have no clue what the student(s) have been instructed to do, but
whatever the goal is, the activity we see performed here is very
unlikely to help achieve it. Those who set this up are responsible for
fixing it; they can't just set up a half-baked project and then hope
that OSM is somehow going to fix it.

I am absolutely hostile towards projects treating OSM like an
ever-forgiving receptacle into which you can pour anything half-baked
and "the others" are somehow magically going to make it right. This is a
deeply disrespectful attitude towards all those who are already spending
lots of time building OSM.

And if the occasional threat of reverting the whole lot is required to
nudge the people managing such projects towards more diligence then
that's a good thing for all of OSM!

[Talk-us] Senseless Sidewalks, again.

2018-07-25 Thread Frederik Ramm
Hi,

we had a long-ish discussion here (or was it over at imports?) about
adding sidewalks, especially related to a project called "OpenSidewalks"
which boldly announced a massive attempt at doing so.

I recently stumbled across this changeset in Austin, TX:

 https://www.openstreetmap.org/way/603909001

In it, an untagged line was added 24 days ago, with a vague promise of
using JOSM later to add relevant tags, which hasn't happened yet.

What's more, there are some erratic sideways in the same area,
un-connected to the road network and un-connected to each other, see e.g.

https://www.openstreetmap.org/edit?editor=id=603909004#map=21/30.28318/-97.74670

and as such hardly usable for anything like pedestrian routing. And they
don't even look good on the map. I really wonder what the purpose of
this is. At least they're all tagged with "project=OpenSidewalks" which
makes it easier to delete them once the project has run out...

wenn man building:levels erfasst - das ist ja doch ein bisschen
einfacher als eine echte Höhenmessung - macht es ja einen ziemlichen
Unterschied, ob man es mit einem Altbau-Stadthaus mit 3,50m hohen
Stockwerken zu tun hat oder mit einem Neubau mit nur 2,40. Sollte man
das irgendwie mit erfassen?

Ausserdem haben Gebäude in der Stadt oft so ein "Hochpaterre" (?), wo

The server move is currently eating up all the extra resources that OWG
have (and more). We'll certainly be able to document it after the fact,
but there is no free time available to provide any running commentary
for the public while the move is being planned and executed.

The decision for Amsterdam was made after carefully reviewing the
bids/offers that were received in response to the request for proposals
put out in February this year. The request also explained why the move
was necessary.

Yes, the situation would be more relaxed if work were distributed on
more shoulders but at this precise point in time I'd like our operations
group to focus on getting the move done with minimum fuss, and not on
recruiting new people!

Wenn ich so drüber nachdenke, denke ich: Das Problem ist weniger, wie
hoch der Berg ist oder ob es doch eher nur ein Ameisenhügel ist.

Das Problem ist, dass OpenStreetMap nicht das Medium ist, mit dem Du
Deine Namensgebung veröffentlichst. Wenn Du denkst, dass Du das Recht
hast, irgendetwas zu benennen, dann solltest Du das auf dem dafür
üblichen Weg verbreiten - keine Ahnung, wie man vor OpenStreetMap Namen
von neu entdeckten Bergen festgelegt hat, aber sicherlich gibt es dafür
einen Prozess, und wenn der nur heisst "man bewegt die Dorfältesten
dazu, den Namen zu benutzen, und eine Generation später ist der Name
überall bekannt, und dann wird es auf den Karten so eingezeichnet".

Wenn Du es dann geschafft hast, dass der von Dir vergebene Name
allgemein genutzt wird (für geeignete Werte von "allgemein" - wenn der
Hügel nur lokale Bedeutung hat, reicht es vielleicht schon, wenn die
Mitarbeiter des örtlichen Forstamts ihn so nennen), dann kommt der Name
auf die Karte.

Der Name kommt aber nicht auf die Karte, *um* die allgemeine Nutzung
voranzubringen.

[Talk-us] admin_level=8 boundaries in Parker County, TX

2018-07-09 Thread Frederik Ramm
Hi,

I've recently traced a little bit of stuff in Annetta, TX. The area I
looked at had a lot of potential for someone interested in mapping from
aerial imagery (houses, tracks, driveways, parking missing; some
driveways tagged as highway=residential etc.) and I did what I could in
the small area I worked on, but there was one thing I didn't dare touch
and that's admin boundaries. The ones I encountered often cut straight
through residential buildings and I thought that can't be right, but I
know too little about boundaries in the US to fix any of it. I am
specifically talking of

https://www.openstreetmap.org/relation/114418

and

https://www.openstreetmap.org/way/33245202

- maybe someone local wants to give them a closer look. Maybe it's ok
the way it is. The Annetta North boundary is relatively straight but has
one wobbly bit, is there maybe a waterway missing in OSM?

This thread started when I said that imports can often be damaging to
community building, and people innocently asked if I can back that up
with facts or research.

Now of course it is extremely difficult to do research in this
particular area at all; you can't just design an experiment and let it
run for 10 years and see what happens. That we have any research at all
about this topic, and not just anecdotes (of which there are of course
many), is very valuable.

Of course it is always very tempting to discredit research that doesn't
agree with one's strongly held beliefs. "When I said show me some
research, I meant THE OTHER KIND of research!!!" - I would probably
start looking for flaws in a study that branded a data import as a huge
success kickstarting a vibrant community too ;)

Anyway, I'm fine with a discussion based on gut feelings and anectdotal
evidence. Just don't ask me to prove my point with research if you're
not interested.

A very very long time ago, when the US data consisted of about 99.9%
untouched TIGER import, all road connectivity was broken at every county
border. County borders had not yet been imported so you couldn't just
mosey along the county boundaries and mend roads either. Andy Allan,
then working for CloudMade, ran a connectivity check by building a
matrix of (100 by 100? don't remember) bigger cities and compared the
routing distance to the bee line distance. Where the routing distance
was larger than bee line by a factor of larger than something like 1.5
(don't remember), the entry was highlighted as "potentially affected by
a connectivity issue" that humans could then hunt down.

I fear the approach will need quite some adaptation to work in rural
Africa but maybe it works on the small scale.

Conflate into a point maybe - by moving the outline's tags onto one of

I recently stumbled upon

https://www.openstreetmap.org/#map=15/-6.8958/39.1623

(Tanzania) and had a similar thought. The buildings there are at least
square and largely match aerial imagery, but this, too, looked like
supercharged one-trick-pony image tracing combined with very little on
the ground knowledge (e.g. quite a few roads and tracks clearly visible
on the imagery are not traced, and from someone local you'd expect the
occasional POI or label).

Someone must have buildings very high on their priority list (don't even
know if HOT are involved but it certainly doesn't look like local mapping).

It will be interesting to learn why buildings are so important. Or are
they just the lowest-hanging image tracing fruit, or just easier to count?

I think that this simply means we need much better name QA in the

Until now we've practically let every language enthusiast add their
names to places far and wide without asking for sources; in the future
we should ask for verifiable sources.

We're ready to accept a local person's authority about local features;
but that doesn't mean that I as a speaker of German should necessarily
have the (un-questioned) authority to assign German names to places on
the other side of the planet.

I expect that a close look at international place names from this point
of view will probably enable us to get rid of quiet a few "Pont Neuf=New

Re: [OSM-talk] OpenStreetMap Carto design

2018-06-29 Thread Frederik Ramm
Hi,

   without going into the finer details, I'd like to offer an outsider's
view of OSM Carto development.

When Andy first created OSM Carto, he set out a road map that has long
been superseded but thanks to version control we can still look at it:

https://github.com/gravitystorm/openstreetmap-carto/blob/v1.0.0/README.md

Essentially it was:

v1.0 - re-implement existing stuff in carto
v2.0 - make it more suitable for further development and customisation
v3.0 - tackle the ticket backlog

What has happened instead is that the easier-to-handle v2.0 was
reasonably successful in attracting volunteers, and now we have a small
team instead of one person doing the style, which is great. But after a
while this small team has started milking the toolchain for all it's
got, and meanwhile the SQL queries are so complex that they threaten to
nullify any effort that has gone into making the style accessible to new
participants (or people who want to customise it).

So the ease of participating or customising has more or less already
gone down the drain; what's still good about OSM Carto is that at least
you can easily install it as-is on your own infrastructure (I regularly
do that for business clients), but I fear it is only a matter of time
until this aspect of usability, too, will be abandoned, and you will
have to run massive pre-computation jobs in order to even get your map
off the ground...

Personally speaking, the OSM Carto map has been good enough for me and
all my use cases for years now. If anything, I found the inflation of
icons and special cases a bit irritating. I would love it if OSM Carto
could be split into a "bread and butter" style that is easy to work
with, easy on the eye and easy to render, and a "cartography
navel-gazing" add-on where we show off how we can render different track
patterns depending on the pebble size. We could then offer both on
openstreetmap.org (where the bread-and-butter style would be the default).

But I'm not involved in OSM Carto development and I won't tell people
how to do their job. Occasionally when I look at OSM Carto tickets I am
in awe about how much work goes into seemingly minor things - how
details are diligently discussed, tried, tested, discarded, done
differently, until they finally come to fruition in a release one year
later. It is great to see this much work and enthusiasm invested in OSM
Carto, and if the price for that is complicated SQL queries then so be
it - the "bread and butter" style I was thinking of could be made by
someone else too.

We try not to show the world according to diplomats and international
law, but according to the reality on the ground. If something is
illegally occupied by space aliens, then we will show it as space alien
territory, because space aliens is what you have to deal with if you
should want to travel there.

Our data will usually contain hints about the finer details, but our map
is not a political map and nobody benefits from us showing theoretical
claims that are out of sync with reality.

I think that while it would be ok for any of these to be used by a
smaller group to actually do some work, the smaller group should come
back to the mailing list for anything of importance. (The same applies
to in-person meetings btw, for example if you were to try and get an
import approved at a SotM conference or so.)

For example, a process where someone pops up on the mailing list and
says "I have this data but I don't know how to import, can someone
help", and then a smaller group huddles together on Slack/IRC/in a pub
to flesh out a proposal, which then goes back to the mailing list for
approval or feedback, would be totally ok and likely more productive
than going every step on the mailing list. But what you can't do of
course is say "we discussed this on Slack and decided we want to do it
that way, now be quiet you weren't there" when someone suggests an
improvement on the list later.

Apart from the reasons you mentioned, having a record is also an
important factor. Anything that has gone on on these mailing lists is
practically archived forever and for all to see[*] but when I'm told "we
discussed this on Slack" I have no chance of checking if there was
indeed a discussion or just one guy with a big mouth and two of his pals
applauding ;)

It has been pointed out to me that there is 1983 document on North
Korean place names by the United States Board on Geographic Names in
North Korea. A Google-digitized, public domain version is viewable online,

https://hdl.handle.net/2027/pst.15364708

in English only, and the coordinates rounded to full arc minutes (i.e.

[OSM-talk] Redactions in North Korea

2018-06-02 Thread Frederik Ramm
Hi,

most of the place names in North Korea had been copied from a web
site called "38northdigitalatlas.org". We have received a complaint from
the copyright holders about this. The user who added the information has
admitted to copying it. The copyright holders have asked us to remove
the data. We have tried to convince them to allow us to keep it but it
wasn't possible, so I've redacted the affected place nodes (and some
boundaries) in https://www.openstreetmap.org/changeset/59473904.

If you happen to have access to material than can legally be used to
re-add some of the now missing place names, then your help is very
welcome. Please be meticulous in specifying your sources when adding
place names though - we don't want to re-import 38northdigitalatlas.org
data through the back door. This particularly applies to information
sourced from Wikipedia/Wikidata - please do not use them as sources.

[OSM-talk] what can be mapped - temporary, pernament and reoccuring

2018-05-25 Thread Frederik Ramm
Hi,

   I think it is not possible to make clear distinction here. You write
yourself that

> OpenStreetMap is not a place to map events that happened in the
> past or will likely happen in the future. 

and then you write that you want to map

> a flea market present on each Tuesday, regular
> street otherwise (maybe with some street markings).

How infrequent does the flea market have to happen in order for it to
become an un-mappable "event"? Take a Christmas market for example,
which is like a flea market just less frequent... or is it an event already?

I think the key here is, like so often, verifiability. Things in OSM
must be verifiable, and I'd like to add "... with reasonable effort by
an average person". If something is verifiable only with expensive
special gear by a person with a doctorate in physics, then maybe OSM is
not the place. Same with recurring things - if their frequency is so low
that the effort to verify them becomes unreasonable, then don't map.

My gut feeling is that something that happens once a week is reasonably
easy to verify. Something that happens once a month, mmh, maybe ok.
Something that happens once a year is, in my opinion, too hard to verify
and should be left out.

(I don't mind someone mapping the Christmas market, or Burning Man, once
it is set up, and deleting everything again when it's packed up. It just
shouldn't be in OSM while it's not in the real world.)

[Talk-GB] Corrections for Ewelme, Oxfordshire

2018-05-13 Thread Frederik Ramm
Hi,

someone claiming to have lived there for over 40 years has emailed to
DWG a list of corrections for the village of Ewelme, Oxfordshire, that I
am sharing in the hope that someone local can deal with them:

--- start

The mapping for Ewelme, Oxfordshire contains some errors in road names.
I should point out that I have lived in the village for 43 years, so I
think I am well placed to comment.

The road between the Shepherd’s Hut and the Kings Pool, running roughly
NW-SE is called “The Street”, not “Clay Lane”.  The real Clay Lane is
actually marked correctly beyond Green Lane.

The extension of The Street beyond Kings Pool (labelled “High Street”)
is also called “The Street” (it was renamed a few years ago).

Similarly, the extension of The Street beyond Day’s Lane (labelled
“Burrows Hill”) is also called “The Street”.  The real Burrows Hill is
actually marked correctly, connecting The Street with Parson’s Lane.

So The Street actually runs from the Shepherd’s Hut to beyond Day’s Lane.

As an addition, the small lane running approximately Se-NW connecting
Eyre’s Lane to Cottesmore Lane is known as “The Pightles”.

I hope that you can incorporate this information into the OSM.

--- end

I'll point the person to this post so if you have any questions, I hope
they will read this.

I think your issue is likely that OSMF has switched to "https only" for
planet.openstreetmap.org this morning. Requests to http URLs are
answered with a redirect to the https URL. Osmosis doesn't honour these
redirects.

You need to change http to https in your configuration.txt.

Hi,

> Frederik's view is that a crap map encourages more people to edit. 

Not quite. My view is that a crap map doesn't become a non-crap map by
erasing one obviously false name, and I was thinking more of our
relationship with the map user and not so much of encouraging mappers.

But I haven't used the word "crap map". OpenStreetMap is generally
great, and it might have the occasional weak spot.

What is being suggested here is what a commercial map maker would do:
Let's take measures to hide the weak spots of our product, so that we
can shine without blemish.

But we ware not a commercial map maker. We can afford to, and should, be
honest with our map consumers. And that includes admitting that none of
our volunteers has had the time to re-visit the area since Toys R Us
went belly-up.

My view is that the map is actually *better* for the consumer if we are
honest with them, because we're including an easily decodable marker
about its quality. A marker that even people who cannot use any OSM QA
tools will understand without extra training.

Rob is of course right that removing the store without re-surveying the
area does remove one error from the map and therefore makes it a tiny
little bit more correct. I'm just arguing for keeping the error until we
can afford to make it much more correct. If that takes a few months then
we have to live with that; doing it right takes time and I'm pretty sure
that doing it right is one thing our users love us for.

Obviously-outdated POIs are the standard user interface for maps to
signal their age and quality. If you take a paper map today, and it
features a chain restaurant that you know went out of business five
years ago, you immediately have an idea of how old/trustworthy the rest
of the map is.

OSM can benefit from this same mechanism. Leave the Toys R Us-es in
place until a local mapper re-surveys the area which might include
mapping any number of other nearby POIs, updating opening times, and
whatnot.

It is easy to run a script that removes all the Toys R Us-es, but that
script would also destroy the valuable information that this general
area of the map hasn't been updated since Toys R Us went bankrupt.

If you could run a script that truly updates the map in the area that
would be another thing, but you cannot; you can only run a script that
removes the obvious "this map is outdated" marker. That might make the
map *look* more current but actually it isn't - the script would just be
window dressing.

Even if there should be agreement that there is a problem here, there
are other potential solutions.

Someone once suggested to have a special tag that indicates which name
tag should be used by default. I.e. we'd have tons of "name:xx" tags
plus one tag called e.g. "language=en", that would then mean: The
default name to use is the name:en name.

I think this would be more elegant than the duplication that you are

I know people of both standard genders who would prefer using a toilet
that is for their gender's exclusive use over a toilet that is for all
genders.

Their respective reasons for doing so are based on unflattering
stereotypes so I won't repeat them here, but there definitely *are*
people who do not only want to know "can I use that toilet" but also
"who else can use that toilet".

Hallo,

ich habe mal gezählt, wie oft "lit" an Ways mit highway=* in Deutschland
vorkommt:

 487245 yes
 180915 no
   2365 limited
336 24/7
308 sunset-sunrise
261 opposite
246 automatic

  7 operating_times
  7 Mo-Su 18:00-24:00
  7 lit=yes
  6 light_switch
  5 unknown
  5 sparsely
  5 operating times

und noch ein paar gequetschte. (Bei "lit=yes" dachte ich erst an einen
Programmfehler, aber https://www.openstreetmap.org/way/565098324 gibt's
tatsächlich).

Wie geht ihr vor, wenn ihr lit=* mappt? Wenn ich am Tage durch eine
Straße fahre und Laternen sehe, reicht das schon für ein "lit=yes"
(sicherlich sind die Laternen nicht zum Spaß da), oder muss ich prüfen,
ob die tatsächlich auch angehen? Das Wiki schreibt, nach der Erklärung
der Laternenring-Ausnahme (s.u.): "Alle anderen Laternen müssen nach
StVO die ganze Nacht über brennen und können auch entsprechend getaggt
werden, ohne eine Nachtwanderung zu machen." - vom Gefühl her
widerstrebt es mir etwas, aus dem bloßen Vorhandensein einer Laterne auf
eine nächtliche Beleuchtung zu schließen, denn bei OSM mappen wir ja in
der Regel, was "ist" und nicht was "nach StVO sein muss".

Berücksichtigt ihr (oder findet ihr, dass man das tun sollte) bei der
Vergabe von lit=* den "Laternenring"
(https://de.wikipedia.org/wiki/Laternenring), der angibt, dass die
Laterne nicht die ganze Nacht leuchtet?

Das Wiki empfiehlt, "lit=yes" auch bei unbekannter Leuchtdauer zu
verwenden, schreibt zugleich (was eigentlich dazu ein Widerspruch ist),
dass man lit=limited verwenden könne, wenn ein Laternenring dran ist.

Ich habe mal gelesen, dass Gemeinden zum Stromsparen nur jede zweite
Laterne die ganze Nacht brennen lassen. Aber ich kann doch in so einem
Fall die Straße nicht in lauter 50m lange Stücke unterteilen, die Hälte
mit lit=yes und die andre Hälfte mit "lit=". In gewisser Weise
ist ja schon die ganze Straße beleuchtet, auch wenn nur die Hälfte der
Lampen an ist. Bloß halt nich so gut...

Und was ist, wenn auf einer Straßenseite Laternen sind und auf der
anderen nicht?


So viele Ways haben lit=yes, nach Straßentyp:

 178893 residential
  60099 footway
  58973 secondary
  39344 tertiary
  32147 service

Mich wundert, dass lit=no so oft explizit an Autobahnen getaggt wird,
obwohl es ja der Default zu sein scheint
(http://www.sueddeutsche.de/auto/strassenbeleuchtung-an-autobahnen-weniger-licht-mehr-sicht-1.1959510).

In the PR footer it also has a nice explanation of why so many
businesses are so eager to apply Machine Learning to OSM:

"By applying artificial intelligence tools and machine learning
algorithms, imagery and data can yield critical insights about land use
and land change, vegetation, the built environment and much more.
Discover how location intelligence is transforming the way businesses

OSM is the ideal test bed for a business wanting to hone their "machine

fix it, and you can then use these fixes as a new input for your machine
learning system...

... which will thereby of course fall fully under ODbL ;)

Without knowing you, or the particulars of the mapping, or the other
mapper, let me suggest one thing: Try to see this from the side of the
other person. Imagine:

* you have been doing a lot of mapping in your local area;
* you have developed a certain way to map certain objects, that might be
a little out of touch with what is considered the "right" approach
elsewhere in the project, but you don't notice or care;
* someone you don't know decides that the way you've been doing it is
wrong, and sets up a challenge in some sort of task managing program you
don't know;
* one or more other people who have never edited in your area, suddenly
start appearing and making very particular changes, driven, as you find
out, by the task managing platform.

This can easily create a sense of "I'm under attack" in the individual
mapper. They weren't consulted; they weren't aware; all of a sudden, the
locusts are there, and the mapper doesn't even know who sent them and
why. Someone has overruled your judgement and doesn't even bother
explaining it to you.

Now if you're a seasoned OSM contributor then it would probably not take
you long to find out that there's a MapRoulette task, and probably also
a discussion or explanation related to that, and also whom to contact if
you want to raise an objection - but not everyone might have that level
of knowledge.

I think that it is no surprise that "making you feel good contributing"
might not the foremost thing on the other mapper's mind at that moment.

Not assigning blame to anyone here; just trying to help humans
understand other humans.

[Talk-de] FOSSGIS-Mitgliederversammlung am vergangenen Donnerstag

2018-03-26 Thread Frederik Ramm
Hallo,

vergangenen Donnerstag abend war die FOSSGIS-Mitgliederversammlung. Ein
detailliertes Protokoll wird noch veröffentlicht, ich wollte aber zwei
OSM-relevante Personalien schon vorab loswerden:

1. Christoph Hormann (imagico) wird vom FOSSGIS als Vertreter in das
"Advisory Board" der OSMF entsendet. Im "Advisory Board" haben alle
OSMF-Local Chapters einen Sitz, ebenso wie gewerbliche OSM-Mitglieder
vom "Silber"-Status (EUR 5000/Jahr) aufwärts. Das "Advisory Board" hat
zwar formell nichts zu bestimmen, aber ich denke, dass es in Zukunft
schon einen gewissen Einfluss in der OSMF enfalten wird. Ich bin sicher,
dass Christoph die Interessen der deutschen Community ausgezeichnet
vertreten wird und danke ihm, dass er den Job macht.

2. Michael Reichert (Nakaner) hat sich auf der Mitgliederversammlung
dafür stark gemacht, dass die OSM-Community sich im FOSSGIS e.V. mehr zu
Hause fühlen können soll, und daher haben wir ihn gleich zum Leiter der
Abteilung "OSMF Local Chapter" im FOSSGIS bestimmt. Da er jedes Posting
auf der Mailingliste und im Forum liest, noch fast bevor es geschrieben
wurde, hat er den Finger ganz dicht am Puls der Community und ist
bestens geeignet für diese Aufgabe.

Was aber nicht heisst, dass die beiden jetzt alles allein machen wollen
oder sollen; Einmischung jeder Art aus der OSM-Community (ob FOSSGIS-
oder OSMF-Mitglied oder nicht) ist nach wie vor stets willkommen.

Für Unternehmen ist das nicht so relevant (ein Unternehmen kann ja jede

spenden oder Würstchen kaufen und auf der Strasse verteilen).  a

Für Privatleute schon, und manchmal hängen auch weitere Vergünstigungen
an der Gemeinnützigkeit, z.B. bekommt man bei PayPal günstigere
Konditionen, oder diverse Arbeitgeber bieten an, dass sie Spenden
verdoppeln, die ihre Mitarbeiter an gemeinnützige Unternehmen geben.

Dem gegenüber stünde ein beträchtlicher einmaliger Aufwand für die
Anerkennung als "charity", sowie ein erhöhter Aufwand bei der
Buchhaltung. Im Augenblick will wegen "Brexit" niemand das Fass
aufmachen - nicht nur ist der Aufwand hoch, man weiss auch nicht, welche
Folgen der Brexit für die Organisation haben wird, und ob nach dem
Brexit vielleicht plötzlich der Charity-Status gar nichts mehr nützt
oder der ganze Verein in ein anderes Land umziehen muss.

Also es wird immer mal nachgefragt und gibt durchaus Interesse am Thema,
aber tendenziell wollen wir da erst nochmal abwarten.

Firstly, many rules in OSM are not written down. Just because there's no
policy that says "don't do X" doesn't mean that X is welcome in OSM, or
that someone who got their X deleted has a legitimate basis for a complaint.

The current situation with written rules is that
http://wiki.openstreetmap.org/wiki/Key:description
says "Never use description=* to add advertising messages.", and
more generally our "How We Map" rules
(http://wiki.openstreetmap.org/wiki/How_We_Map) say that what you add
must be truthful and verifiable, both of which is rarely the case for
advertising.

Bei humanitären Mapathons geht es oftmals nicht in erster Linie um die
Kartendaten, die dabei herauskommen (denn deren Qualität steht oft in
einem schlechten Verhältnis zum Arbeitseinsatz, und da generell die

Du kannst natürlich jederzeit auch ausserhalb des Mapathons mappen.

Frankly, I'm finding there is way too much AI talk in OpenStreetMap

eager to get rid of that pesky limiting factor "human" and quickly have

But of course you're right and spam detection is a classic area for

the same thought over on talk-us when I published a similar list (albeit

[Talk-GB] unwanted advertising in OSM in the UK

2018-03-07 Thread Frederik Ramm
Hi,

I've identified around 60 locations in the UK that sound very much like
advertising in the "description" tag.

I haven't inspected them, but more often than not such POIs don't only
sport marketing copy in the description tag, they also tend to lack the
usual shop/amenity/whatever tags that tell you what this is supposed to be.

If someone is interested in having a look:

http://www.remote.org/frederik/tmp/seo-uk.txt

or as a .osm file

http://www.remote.org/frederik/tmp/seo-uk.osm

(note if you want to use that in JOSM you should do "update data" first
in case someone else has already dealt with some)

These likely aren't the only "spam POIs" but they're the most obvious.
Some of them are close calls, where the description only has a list of
services, or where the advertiser is a non-profit or even an over-eager
mapper copying from a sign. Hence I'd rather see UK mappers have a look
and decide what of this is worth keeping, than deciding it from the
comfort of my armchair.

[OSM-talk] Please do not re-use old node IDs

2018-03-06 Thread Frederik Ramm
Hi,

we're all concerned about the environment these days. "Reduce, Reuse,
Recycle" is certainly something to strive for in the real world out there.

However, for the second time now I've encountered a user who thought it
was a good idea to reclaim old node IDs for new edits. A couple of
long-deleted TIGER nodes were raised from the dead, and put to use in
mapping some new roads on the other side of the planet.

This sounds like a funny/quirky thing to do, and looks harmless enough
on the surface. But anyone who ever looks at the history of things
*will* be totally confused. Nobody who works with historic data will
expect that a U.S. bus stop could become a tree in Romania. People are
bound to interpret this in any number of wrong ways. It also messes up
my full history extracts, where you'll now find the occasional German
hiking route in the California data extract because a node that used to
be in California is now part of a path that belongs to the hiking route.

Long story short, please don't do it - let the API assign you new node
IDs to your stuff instead of building ingenious contraptions to recycle
old nodes.

Thanks
Frederik

Well strictly speaking it will ensure that the algorithm follows the

biased ;)

There's work afoot for the OSM web site to allow changesets to be
flagged as spam by any mapper. It isn't clear yet if/how the list of
flagged objects will be publicly accessible but of course it could also
serve as food for the filter.

We're leaning towards a cautious approach, i.e. not "spend it all for
something cool" but use the money spread across several years. It is
also clear that it would be unwise to use a one-time donation for
anything in our ordinary budget lest we'd have to find a similar donor
regularly!

At the last face-to-face meeting of the OSMF board we discussed plans to
run a "microgrant" scheme which could pay for things like (but not
limited to) coding projects in the OSM ecosystem. It is possible that we
will use part of the Pineapple Fund money to start something like this.
Details, however, still need to be worked out and no final decisions
have been made.

We have exchanged 15 of the 18 BTC that we received and got £146k from
it. This was thanks to Grant Slater who picked a very good time to make
these exchanges. The remaining 3 BTC are still in our account but we
will sell them as soon as we have a good opportunity.

I'd like to think of your approach - contact the business that is
advertised, through the contact channel they voluntarily publish, and
ask whom they've contracted for advertising - as the "front door"
approach which I find preferable to the "back door" of trawling our logs
for IP numbers and trying to find out who's behind it. Firstly, the
"back door" approach is limited to those in OSM who have the requisite
privileged access; secondly, it is likely to land you with
subcontractors who have little interest in a cooperative future vision
because they're just doing what they are told.

So +1 for more people following the front door approach, and compiling a
list of SEO companies and cataloguing their efforts and reaching out to
them to politely requires compliance. In my opinion, this is something
we should do as a community, locally, and not wait for someone to lead
the effort.

I think that "making it easier for them to conform" should have its
limits in us defining and communicating the envelope of acceptable
contribution. Suggesting that it should be us who develop software or
invest time in curating third-party data sets would sound a bit
disingenious to me; next thing that someone suggests is because we're
doing their work for them we should also charge them? I wouldn't want to
go down that route.

And of course the non-confrontational approach can only ever be the
carrot, and there must be a stick to complement it. For every conformant
SEO company there will be a dozen who try to game the system, because
gaming systems is their core business, that's what they do with Google &
Co.; and even if we found some way to keep more advertising from
entering OSM, there's several thousand advertising POIs in OSM in the US
alone and they won't magically go away. So let's roll up our sleeves and
get to work.

Yes, the locksmith advertising was one step up again - this wasn't even
"unwanted advertising for a legitimate business" but "unwanted
advertising for a scam". One mapper had verified one of the "local
locksmith" locations in person and found it to be bogus, then called the
telephone number given and was connected to (he said) an "outsourced

The list I posted does contain a number of businesses that sound a bit
shady - if not outright scams, then at least preying on those in
difficult situations. Loan sharks, lawyers with dubious offers, people
who claim to buy homes for cash and the like. Sometimes it's hard to

I've come across a lot of edits where mappers had written changeset
comments against one of these one-off accounts, and were met with
silence. It's not normally something the individual mapper would
escalate - they write a comment and then forget about it, or simply fix
it themselves after a while.

I have also (sorry for the "lurkers support me in email" argument)
received positive feedback from mappers about my deleting of
advertising; twice, a mapper wrote to me along the lines of: "I've been
annoyed by this for a while but I didn't dare remove it".

> Have we asked the Operations team to

I have on occasion done that with my DWG hat on (when there was a
particular flood of such edits) and it was usually possible to identify
an IP address or email domain which was then blocked. However this is
usually doesn't help for long.

I don't think we're dealing with one single opponent here, I think
there's an industry out there, and even if you successfully stop one
firm from harming OSM, there'll be the next one just around the corner.
If you get one to play by the rules, there will be the next one sensing
a business advantage by ignoring the rules. (Or "being disruptive" in
modern speak.)

I don't know. It has never worked when I tried but I might not have
tried hard enough. I think their (and their clients') interests differ
too strongly from ours. Their goal is certainly not making the best map
(or the best geodatabase).

> Also, your characterization of US mappers being more lax about this is a

The US mappers are not more lax, but there simply are less of them, and
they are concerned with more important things than watching their home
turf for an unwanted item. Combine this with a more intensive spam
activity in the US than elsewhere (some spammers operate world wide but
many seem concentrated on the US even if they hail from non-US IPs) and
you get the current over-abundance of spam in the US. It's not your
fault, and I'm not pointing a finger - I'm asking for help.

There's certainly things that can be done policy-wise, establishing
rules that can then be communicated to those willing to play by them;
the upcoming directed editing policy will be helpful in outlining
acceptable behaviour for groups who wish to contribute business
information. But that's a different activity; the advertising that we
currently have in OSM must be weeded out no matter what.

I think you're misrepresenting it when you say "security rather than

Thing is, at OSM we depend very much on the community policing itself.
It would not be feasible to have just a small group dealing with problems.

Knowing about other edits made by the same user around the same time can
give important context to judge whether something is vandalism or an
honest mistake. If we take this information away from the community, we
lose their help in quality assurance which we desperately need.

However, I think it would be possible to limit this information to "the
OSM community" i.e. everyone who has an account, and to make these
people promise that they will not abuse the data for non-OSM purposes.

This means that I can still see what you did last summer, but I wouldn't
be allowed to use that information for non-OSM-related purposes.

This is a weak protection but I don't see how we can allow stronger
protection without employing a huge, privileged QA task force that has
access to user information and can therefore judge better.

[Talk-us] Help fight advertising

2018-03-01 Thread Frederik Ramm
ncounter and not just
those who happen to pay money to an online visibility enhancement firm.
If we allow advertisers to flood OSM with POIs, even *if* they had none
of the flaws above, OSM would still lose its appeal of being made by
locals who know best.


What should I do?

Advertising has no place in OSM. If you encounter advertising, you have
a few options:

* Contact the mapper responsible and politely ask them to fix it and/or
stop adding advertising. In most cases, since these are throwaway
accounts created by professional spammers, you won't receive a response
but when in doubt, try it.

* Leave the factual information in place, remove only the advertising. I
recommend to do this only if the factual information seems correct and
meaningful and at the right place; if the factual information is only a
name and an address, ask yourself: Should *you* be the one who completes
the SEO company's job for them, or rather delete the whole business?

* Remove the node altogehter - recommended if the tagging is buggy.

* Use the business contact information provided to call/email them and
ask which SEO firm they have paid to add data to OSM, and explain how
this volunteer project is damaged by the actions of the SEO firm and
that this also tarnishes the business reputation. Recommended if you
like a little fight; some SEO operations have already been stopped from
abusing OSM that way.

* Should we have some MapRoulette task or OSMCha automatism or OSMI view
to detect potential advertising?


Examples of advertising in OSM

I've made a list of roughly 1750 nodes in the US, sorted by state, that
look suspiciously like advertising. The list is algorithmically
generated and almost certainly has the odd false positive, where a
mapper simply described where exactly the rare tree is hidden and my
algorithm thought this must be advertising, or where something really is
just a harmless description of products offered. The list is certainly
not exhaustive; I'm sure that using Overpass to search for tell-tale SEO
signs you can come up with may more.

The data is in CSV format with the columns:

date_last_edited,object,created_by,last_edited_by,name,description

If you're in the mood, grab a few and kick out the most outrageous
abuses of OSM. And maybe we can establish ways to make this a habit in
the project. Ideas welcome!

I wanted to include the list here but that would probably have condemned
this message to spam filters, hence:

http://www.remote.org/frederik/tmp/us-seo.txt

You will be surprised about the breadth of marketing blurb that has
already crept into OSM.

My thinking here would be: 90% of the value of what you produce will be
in the surveyed stuff - as John said, number of levels, type of building
etc.; what he didn't mention but what certainly could also be
interesting to some is the 3D modeling tags like roof shape information
which will make the building look nicer on 3D maps.

If 90% of the value is in the "handmade" stuff anyway, why even depend
on an import for the remaining 10% - isn't there aerial imagery from
which you can trace the building? With proper tooling this is quick and
painless, and a student who has actually "drawn" the houses will feel
much more pride in the resulting map as one who has simply taken
existing data and uploaded it to OSM. One is a creative task, the other
just data mangling. I'm pretty sure students would warm more to the
creative task.

Best
Frederik

[Talk-de] OSMF sucht Rechenzentrum

2018-02-19 Thread Frederik Ramm
Hallo,

die Operations Working Group der OpenStreetMap Foundation hat den
Großteil ihrer Server, u.a. diejenigen, auf denen die API(-Datenbank)
läuft, in drei britischen Rechenzentren stehen. Eines der drei muss
geräumt werden, da die Räumlichkeiten künftig anders genutzt werden.

Die OWG sucht daher ein Rechenzentrum in der Europäischen Union, dessen
Netzwerklatenz zu den bisherigen Standorten idealerweise unter 20 ms
beträgt. Gesucht wird ein Rack für die Server, die sich im Eigentum der
OSMF befinden. Weitere Details zur Ausschreibung findet ihr hier:

https://blog.openstreetmap.org/2018/02/19/osmf-request-for-proposals-data-centre-2018/

Die OSMF ist bereit, für die Dienstleistung zu bezahlen, kann sich
jedoch keine marktüblichen Preise leisten. Potentielle Standorte sind
daher Hochschulrechenzentren oder gewerbliche  Anbieter, die das Projekt
unterstützen möchten.

Wir denken, dass es sicherlich potentielle Partner in Deutschland gibt.
Es würde auch zum nicht unerheblichen Anteil der deutschen Community am
OpenStreetMap-Projekt passen, wenn wir nicht nur zu OSM beitragen
sondern auch einen Rechnerstandort in Deutschland hätten.

Die OWG hat leider nicht die personellen Ressourcen, um potentielle
Partner zu kontaktieren, daher sollten wir uns als deutsche Community
ein bisschen an der Arbeit beteiligen.

Hat jemand von Euch möglicherweise Kontakte zu potentiellen Hostern -
gewerblich oder im Hochschulbereich? Habt ihr Ideen, wen man fragen könnte?

Meldet Euch doch hier mit einem Followup oder direkt per Mail an Michael
oder mich, und wir koordinieren dann das Vorgehen ein bisschen.

Viele Grüße
Michael Reichert und Frederik Ramm

Many people seem to believe that the natural growth path for a nonprofit
organisation is identical to that of a for-profit organisation. Acquire
more funds, hire more people, invest, grow, rinse & repeat - bigger,
better, faster, more, year after year.

This is certainly a *possible* course of action.

But it is desirable?

Have a look at the OSMF board, a mixed bunch of people elected by the
members. Are you sure that a seasoned developer or sysadmin would even
*want* a paid job where they are subject to the whims of an elected
board, with a potentially modified "strategy" year after year (as
majorities change due to new elections)? Would that not be a job like
Dilbert's with his pointy-haired boss?

Ah, you'll say, easy: We hire a CEO in addition to that, so there is
more continuity, and the CEO can then boss the technicians around, and
the board only adjusts the general direction occasionally. That's also
something people often suggest, again following the usual corporate lines.

Growth of this kind entrenches the power of the established organisation
over the volunteers. Inevitably, the organisation shifts from the
initial "a bunch of volunteers have founded an organisation and elected
a board to do the basic housekeeping of financials and intellectual
property rights" to "a central organisation manages their volunteers".

The growth of the central organisation brings with it increased funding
requirements (salary for CEO, developers, and sysadmins; soon after,
cost for a fixed office, office management, community managers, and so
on). This money has to come from somewhere (add salary for professional
fundraisers). Whoever gives us the money can make all sorts of demands
on our organisation and community. Shrinking the organisation is rarely
an option, so we'll need the funds to continue to live, and we are much
easier to control by "big capital" (if you look at usual funding
sources, you can safely say "big US capital").

We will be subject to politics much more than now; we will have to
publish regular success stories (and gloss over failures) just like any
business does to maintain a good image. We will have to kick out people
in our ranks who soil our image lest the funders will back out. We'll
have to start doing silly side projects that the community would never
have started in their own, just to tick some boxes with a funding partner.

Do we want to sell our soul? And for what precisely in return?

These are important questions to think about. I am sure there are
potential growth paths that do *not* require us to blindly submit to the
ways of commerce - just like we never blindly submitted to traditional
GIS practices ;)

Bye
Frederik

> Please let me know if we can answer any questions!

I notice that the "addr:full" problem from the previous Walmart import
hasn't been resolved. Is this an oversight, or was there a decision by
the community that it's fine to have addr:full instead of proper
addr:street/addr:housenumber etc. tags?

The wiki currently says, about addr:full: "Use this for a full-text,
often multi-line, address if you find the structured address fields
unsuitable for denoting the address of this particular location." and
goes on to warn: "Beware that these strings can hardly be parsed by
software: "1200 West Sunset Boulevard Suite 110A" is still better
represented as addr:housenumber=1200 + addr:street=West Sunset Boulevard
+ addr:flats=Suite 110A."

Since we're only talking 150 or so points here, would it be too much to
ask to specify the correct addresses for each instead of relying on
community members to repair the data post-import?

Das ist in dieser vereinfachenden Form nicht richtig. In OSM entscheidet
letztendlich "die Community", und die ist schwer zu greifen. Selbst "die
Plattform talk-at" ist nur schwer zu definieren und im Fluss, aber
talk-at ist nur eine von vielen Möglichkeiten für die Community, eine
Meinung zu bilden und ggf. durchzusetzen.

Ich finde es gut und richtig, wenn Mapper, die im Rahmen ihrer
Berufstätigkeit zu OSM beitragen, dies auch offen sagen (z.B. "ich
bearbeite OSM im Auftrag der Firma X, um Y zu erreichen").

Wenn jemand allerdings beruflich mit Karten zu tun hat, und privat OSM
betreibt, dann finde ich nicht, dass er oder sie das offenlegen muss.
(Im Gegenteil, vielleicht hat der Arbeitgeber ja sogar etwas dagegen und
die Person müsste berufliche Nachteile befürchten, wenn herauskommt,
dass sie der "Konkurrenz" hilft!)

Du hast im Forum des öfteren den Generalverdacht geäußert, auf den
Mailinglisten wäre das große Geld unterwegs. Ich weiss nicht, was Dich
zu dieser Fehleinschätzung bringt; wir können gern darüber reden, aber
hier reinzuplatzen und erstmal von jedem eine "Erklärung" zu verlangen,
ist ein bisschen unhöflich. Sollen wir Dir vielleicht auch noch
erklären, dass wir unsere Steuern brav zahlen, unser PKW
vorschriftsmässig angemeldet ist und wir noch nie was im Supermarkt
geklaut haben?

Ja, natürlich gibt es in OSM eine große Breite verschiedener Meinungen.
Die Meinung, die sich am Ende eines rund fünf Jahre dauernden Prozesses
durchgesetzt hat und die OSM als Projekt daher vertritt, ist allerdings
die, dass unsere Daten als Datensammlung ein Schutzrecht geniessen, das
wir mit Hilfe unserer ODbL-Lizenz gestalten.
