[OSM-talk] how to map flowing water the easy way?

2009-12-22 Thread Robin Paulson
i had an idea recently, that it might be possible to map a stream or
small river (in an area with poor aerial photo coverage) by using a
gps in a waterproof container attached to a flotation device

i created a wiki page to collect ideas and criticisms, unfortunately
my local streams are all too congested or i'd be trying it. maybe
someone else will find it useful?

[OSM-talk] augmenting contour data with gps track logs

2009-12-28 Thread Robin Paulson
the srtm contour data used in some osm renders is great, partic for
cyclists and walkers. i've realised that it's not as high
accuracy/precision as it might be though. i notice that most GPS
devices also record the elevation within their tracklogs, and that it
might be useful to extract this data, and use it to provide more data
for calculating the altitude of a given point.

any ideas?

ok, i didn't realise that. what levels of bad precision are we talking
about; i assume it varies form model to model; how does it compare to
the precision of srtm?

the idea was not to get people to manually tag the altitude of objects
(like post boxes), partly for the reasons you point out, partly
because it's slow.

my idea was to extract a series pf lat, lon, alt triplet from the gps
tracks, and use this to build a 'mesh' of the earth's surface, which
would be stored independently of the points/ways which we create at
the moment. the implicit assumption being that wherever the post box
or any other object is placed on the globe, it takes it's height from
the underlying mesh. from this mesh, we can then generate contours, 3d
models, etc, etc as we do at present with the srtm data

it was already done in mapnik. is osmarender a completely different

well, the englishman in me gets indignant and says 'use the true

but that starts lots of arguments and is ridiculous

i presume this is for things like 'The Arndale Centre' i.e. proper
nouns (names) of buildings/areas etc? in which case, the spelling is
dependent on whatever the owner of the structure chooses.
if they spell it 'centre', then it's 'centre'.
if they spell it 'center', then it's 'center'.
if they spell it 'senterr' then it's 'senterr'.
imo we're here to reflect reality, not make political or otherwise
statements about the validity of any language or dialect over any
other

or maybe it's for the name of the actual tag key? in that case, it
doesn't really matter - whatever the proposer comes up with. i would
hope there wouldn't be any silly arguments over which to use, so long
as everyone sticks to it when they map

or do the renderers check for alternative spellings?

well, that's got nothing to do with me/us really. we're not creating a
map, we're recording information that can be used for a map. it's up
to the maintainers of the renderers to decide what info to show. if
they want all industrial areas (including airports, sea ports, etc) to
show as one colour then they can. if they don't then they can display
them as many colours. but if we log them all as the same, they have no
option. there cannot be too much information - disk space and
bandwidth are not an issue (as far as i'm aware).

maybe this would be a good location for storing more info on items?

we could have a new tag, something like:

where wikimapia id number is the 6-digit number corresponding to the
item in question? and clicking on the link icon for the item opens it

no need to create a new site, this is exactly what wikimapia.org is for

as far as i can see, there are no limits on 'importance' as there are
on wikiepdia, so every little square, street, park, pub, supermarket,
etc can have it's own page, and it already has huge amounts of data on
hundreds of thousands of POIs

it currently overlays it's data on to google map tiles, it would be
nice if they were switched to OSM/OAM tiles

purely a renderer issue i know, but the current way of showing it is a
bit confusing - it may need to be drawn with thickness, to indicate it
has a substantial depth. at the moment, i look at that and think it's
a line, i.e. a road, path, boundary, etc.

maybe it should render as an area, with an automatic width of whatever
the average depth of terrace houses is, possibly with 'dividers' to
show that there are multiple items?

getting some data for new zealand would be fantastic, there's very
little outside the main cities. however, we are investigating some
other mass data imports, which are probably better quality than vmap0,

[OSM-talk] POIs from wikipedia

while i was looking up some info on wikipedia [1], i noticed that a
lot of pages have a lat/lon value to describe their location; this
strikes me as something we could use to increase the amount of data in
OSM

it would require a mass download of data from all the pages that
contain these values, matching to relevant tags and importing into
OSM.

dos anyone here have the experience to query the wikipedia db in a way
that could pull out just those pages with location info?

bad i know, but replying to my own mail:

http://de.wikipedia.org/wiki/Wikipedia:WikiProjekt_Georeferenzierung/Wikipedia-World/en

has a database of all georeferenced POIs in SQL format

i realise a lot of these will be in OSM already, so there would need
to be some cross-referencing/filtering to prevent duplication

suggestions, comments? has this been done already?

in england, aus and nz, they're quite different. newsagent is
generally a proper shop with a big range of items open longish hours
and in a building. kiosk is s small shack on the pavement, with a
small range and usually open only in office hours

i'd say keep them both

[OSM-talk] administrative boundaries and is_in

2008-01-09 Thread Robin Paulson
can someone explain a few things about the way boundaries work, and
their relation to the is_in key?

as far as i can tell, when a location (say the suburb of balham, in
london) is added to the map, the is_in tag needs to be set, multiple
times. in this case, it would be set as follows:

is_in:Westminster (...i think)
is_in:greater london
is_in:england
is_in:united_kingdom
is_in:British_Isles
is_in:Great_Britain
is_in:Europe
...etc.

which seems counter-intuitive, not to mention requiring huge amounts
of work. do we set this for every item - roads, churches,
supermarkets,thousands of other items?
is there anything underway to enable OSM to calculate where an object
is, based upon knowledge of administrative boundaries - after all,
they are only a polygon-shaped bounding box?

if i set is_in of balham to london, and the is_in of london to
england, does osm know that balham is therefore in england, by
cascading the is_in values? and so on, for as many levels as we
define?

my second, related, point concerns boundaries that coincide with
coastlines: do we need to trace over the coastline of a
country/city/suburb to define an unbroken loop for each administrative
areas, or can OSM work out for itself that the coastline forms the
rest of the boundary? what about if the entire boundary is defined by
coastline? are these questions only relevant if and when items are
automagically aware of their location?

thanks for any help

it does, cheers

i'm slightly lost now, wondering how osm fits in to this. if wp users
can do it (i assume their legat team has looked through it?), why not
osm

i guess it's ok, because they're using it for illustrative purposes
(fair use?), rather than as a basis for their content

ok, i'll keep looking and keep thinking. thanks

sorry mike, i'm sure you've put a lot of work in, but that sounds even
more backwards, and very difficult to control well - i foresee a lot
of fudging to make it work in a lot of areas.

the boundary data should be relatively easy to come by, and require a
*lot* less points to be drawn/edited, than your method. plus, your
method is never going to be one hundred percent perfect. for example,
what happens in areas of open country side, with no POIs to mark, when
the boundary changes direction - something that will happen a lot?
and what when a place is in two administrative boundaries? there are
fairly major cities that straddle for instance state lines in the US.
i think arkansas may be one?

but i guess itches should be scratchedsomething will doubtless
come from this, whether unintended or not. ok, it'll be interesting to
see your results

sounds good

the idea of tracing over an existing boundary is not something that
particularly appeals to me though, and as it's been done once, does it
need to be done again:

are there any tools for automating this? for aus, it would be great
for instance to define a bounding box, containing the whole country,
then run some simple commend to 'double up' the coastline ways, to
create the country border

totally right, absolutely.

this has been at the back of my mind for some time now. my gut feeling
about it, is to create the tags the way we are doing now, in
isolation, using the current top-level tags (they are quite
inconsistent and overlap lots, IMO)

at the moment we are seeing a rapid rise in the number of tags
proposed/accepted, and this is going to continue for some months,
after which it will decrease, signifying we have created the vast
majority (we will never fully complete, there will always be something
new)

at this point, we will have a far better, more-rounded picture of what
is happening with tags, how they could be improved, etc.:
does namespacing need to be seriously considered?
should we have such a shallow depth of tags, or a more nested approach?
should railways and highways be joined into one category (this would
remove a lot of arguments.)?
do we need to look at how we define permission son highways?
and many more

at this point, i can see the tag system undergoing a major overhaul

i think trying to make changes like you are suggesting while we are
going through such a period of rapid change, would be a mistake

yes. some examples:

very true, they are poorly selected, but they were based on what was
known at he time - i.e. very little. OSM is still very young, but it
is very easy to make en masse changes as we learn.
some tags are form-based (physical characteristics), some use-based
(conceptual characteristics), which is inconsistent, they all need to
be one or another or we get overlaps. this is one of the first changes
i have been considering proposing, but i think we should wait till
more tags are developed until we do anything

categories make it very easy to select a wide group of items based on
their properties. for highways it would be fairly trivial to select
'primary_road', 'secondary_road'. etc. in a multi-select, but some
categories - shop - will have hundreds of sub-types.

this enables others to very easily make custom maps, only showing the
data they want, by quickly hiding other information

if you have any arguments against a proposal, please join in the
discussion - everyone's opinion is considered

no. this is one area where current maps fall down. what we are doing
enables very easy processing of a lot of tags/groups of tags and to
produce complex queries very quickly

generally because people don't think of it when they're proposing, and
because a lot of discussions get very little attention, so no-one
notices. if you think it needs changing, put it forward.

it is a wiki, everyone is responsible for what goes on - you're as
important and as likely to be listened to as the next person.

i agree

yes. there are dozens of inconsistencies in the tags, but the tag
system is still in it's infancy, we're making it up as we go along and
writing the guidelines day-by-day.

problem is, there are very few people managing the tag proposals
system and they don't have time/the
inclination/wherewithal/inspiration/experience/whatever for writing
guidelines/creating templates. more bodies is always good

there aren't any templates for proposals, it would be very useful if
someone made some updo you want to do it?

if you want to go through the proposals page and suggest changes, that
would be great

[OSM-talk] proposal templates

2008-01-10 Thread Robin Paulson
further to my previous post about editing the wiki, are there any
mediawiki gurus here?

a set of templates (or even one!) for proposals would save a lot of
time, does anyone feel like volunteering to create one? hopefully,
this would give some guidelines for people when proposing tags, and
save a lot of time currently wasted on cleanups

yes. i'm not well up on it, maybe franklin is entirely governed by the

government is rarely logical

yes, that may be true, but still boundaries at a high level do not
have to coincide with boundaries at a low level. i think that was
where this all started

as you can see, i'm not a mediawiki gurui probably got the

it was valid, but they're not really map-worthy. if we go down that
route, where do we stop? every painting?

for example, we would not map the crown jewels, but would map the
tower of london (i think...), which contains them. ditto the Mona Lisa
and the Louvre, and others. map the building/location it's in, not the
contents

ok, let's say i wanted to use this as a basis for drawing the national
boundary for a country. i appreciate that part of the border will be
more than 12nm away from the coast (depending on the depth of the
ocean floor, yes?), but it's a good start

does some enterprising coder want to come up with a way of
automagically drawing the border at a 12nm offset to the coastline?
anywhere that the border is different, i would be happy to edit it
manually, if a large part of it was being done by programmatic means

lame answer i'm afraid: i tried adding one a few days ago, got a in a
hideous mess, table all mangled and everything, took me ages to sort
and i didn't really know how i did it. since then, i've been relying
on one user who seems to be reading my 'proposal accpeted' mails and
adding them to map features for me, can't remember the name, but they
seem better acquainted with mediawiki than me - i hate tables, they're
very clumsy IMO. i should really learn i know... i'll give it a go in
a bit, unless you want to do it?

totally, i realise the tagging system has evolved very quickly form
nothing, it's bound to change over time as we learn new things. my
tone was probably wrong, that is itself a good reason why the tag was
chosen

no problem, they can all be changed very simply i should think.

that is actually pretty logical (for practical reasons) - the
alternative would be one area comprising 99% of the world's oceans.
using a boundary instead, greatly simplifies things, plus the creation
of new oceans/seas is highly unlikely, so once it's done, it's done.
on the other hand, new lakes/reservoirs/etc. are a lot more likely, so
we need a consistent scheme for adding them. i'm sure there are other
good reasons, too
