Instead, try this:

It's in Ruby - though I'm more a Perl hacker than a Ruby one, I had the Ruby
AMF code written for Potlatch, so figured it would be easier to reuse this.
You'll need to install the httpclient and stringio libraries ('gem install
httpclient' etc.). Lots of the amf encoding/decoding logic is in the script
rather than the library, which is clearly a bad thing - I just felt like
quickly hacking up something that worked.

Edit amf_finddeleted.rb so the bbox is what you want, then: ruby
amf_finddeleted.rb

It'll spit out the results in Potlatch's array format, which is documented
in amf_finddeleted.rb (lines 65-70). You could either process it further in
Ruby, or copy-and-paste to do something in Perl, or use YAML to interchange
between the two - whatever.

Well, it's in the main Rails codebase intentionally so someone could do
that, but I'm not comfortable enough with XML to do it myself. If it were to
happen, probably better to wait until after API 0.6 anyway, because I'm
slightly rewriting it as part of that.

Works fine for me, but just returns an empty list - i.e. there aren't any
deleted ways in that area. (The "get deleted ways" call is on the slow side
anyway.)

Yes on both counts: Google MapMaker.

I personally don't want to write the editing interface that the rest of the
world uses, and it's slightly insane that somehow I've ended up doing so
(or, at least, what we have so far) - I mean, I'm not even a programmer, I'm
a magazine editor with not a whole lot of free time. If future-Potlatch were
to become _an_ editor available on the main site rather than _the_ editor,
I'd be very happy.

Of course, CloudMade might already be working on this - can anyone from CM
confirm/otherwise? Would help the rest of us in knowing what to do next.

Have a look at Google MapMaker. We don't have to dumb down; we can offer
both and give people the choice.

Bear in mind that Potlatch was never originally meant to be an editor
specially for beginners; it was meant to be something for _quick_ editing.
The reasons I first wrote it were that (a) JOSM wouldn't work on my machine
(OS X 10.3, so no Java 1.5), and (b) when I did use ye anciente JOSM, I
thought "what the hell is this create node/create segment/create way shit? I
want something that works like Illustrator". So I don't want to dumb
Potlatch down, either.

(Oooh, look at all that lovely untraced Yahoo imagery...)

Yep. Potlatch connects points, breaking whenever there's a time difference
of 3 minutes or more. 

It works very nicely if you have a "natural" GPS track, but can foul up when
someone, say, uploads a track with faked timestamps all the same. Please,
people, if you're going to fake your timestamps, do something like make them
ascend at 1s intervals from 1st June 1970 or something.

Anyway, if you want to see just your own points in Potlatch, simply
shift-click the GPS icon.

Put yourself in the shoes of Google's lawyers - and, more significantly,
those of their data suppliers. The law is unclear here, and Google/BigDataCo
aren't actually losing out by this use. (You could argue they're gaining -
every site which significantly draws on Google Maps reinforces their
position at the head of the ecosystem.) So there would be no gain for them
in a long, drawn-out, involved legal battle against Wikimedia, especially
when you consider the adverse PR.

But if we did it, Google/BigDataCo would be at risk of losing out - their
future customers could use our data instead, or our data repackaged by an
added-value company. Even if BigDataCo had to spend months on the case, it
would be worth them stopping us deriving. So they would sue. (Besides, the
Wikipedia crowd have deeper pockets than us.)

A UK Right of Way legal status, unsurprisingly, is much more nuanced than
simply "horse yes, bicycle yes, foot yes, car no".

So, in itself, it's a valuable piece of information to store in the
database.

Rather than just approximating this with 5,000 OSM tags, let's be precise.
Use a general tag such as "highway=track" so the path is routable/renderable
and so on, but augment with "designation=uk:restricted_byway", so those
applications which want to parse the detailed information can do so.

Eek - people are really doing this?

'yes' is English (and, as you say, in the editor presets). 'true' (in this
context) is computerprogrammerish. Even if there was a need to standardise,
which there isn't, it should be on the former.

A good general principle: we should always optimise for ease of mapping.

If we produce a wonderful world map but developers have to jump through a
few hoops to use it, a) we have a wonderful world map, therefore b) people
will - and are doing - produce the tools that jump through the hoops.

If we make it unnecessarily complicated to add data (and that includes using
jargon words like "true" when "yes" is obvious) then we don't get the
mappers, so we don't get the wonderful world map.

Not true (IMO at least).

We have 100,000 _registered_users_, not mappers. Only a fraction of them
have contributed to the map.

Of them, again, only a fraction have made substantial changes deserving of
copyright* protection.

If someone has put one church on the map, or removed an 'n' from 'Avennue',
or even just done the uncreative monkey-work of tracing over Yahoo imagery,
_most_ jurisdictions will not grant them any copyright over the work. Even
in the UK, which follows the "sweat of the brow" principle (i.e. copyright
can be gained through effort even without creativity), such effort needs to
be significant.

Claiming copyright over negligible works is what the RIAA, and those bunch
of tards who are trying to stop the Kindle's text-to-speech feature, do.
They are rightly vilified for it by people like us. We should be on the side
of the angels, and not try and claim rights where such rights shouldn't and
don't exist.

This should be on legal-talk, but I don't know how to get Nabble to
cross-post. Sorry.

Nah. We don't have enough developers on the OSM core site, but that's
immaterial in this context. The ecosystem, however, is thriving. There isn't
a day when I don't see some new program released that uses OSM data.

Yet we still don't have _enough_ mappers. I'm writing this from an only

Oh, sure, I wouldn't argue with that. Writing better editors is part of
"optimising for ease of mapping".

But Potlatch autocompletes oneway only to yes/no, and from this thread it
seems that JOSM is similar, so in this instance the editors are getting it
right (hey, Potlatch got something right, break out the champagne).

Slightly controversial suggestion: the quickest way to solve this would be
to take "or [oneway]='true'" out of the Mapnik style file. ;)

Sure. And the law is just as ill-defined!

I think it's pretty unarguable that, in the UK, your tracing of the Peruvian
lakes would merit copyright or similar protection (as "sweat-of-the-brow").

I think it's also unarguable that if I trace eight streets in a city, then
in the US, that doesn't merit any copyright protection. I _suspect_ your
Peruvian lakes wouldn't, either, but IANAL and so on.

Between that is shades of grey. Extensive, skilled tracing, which can't
simply be learned in an hour or two, assessed in sweat-of-the-brow
jurisidictions: yes, there's probably some rights in there. Everything else
is much less likely. Really do need to get away from thinking "copyright
applies to everything we do". If that was the case then CC-BY-SA wouldn't be
so unsuitable.

I'm not knocking Yahoo tracing - it's not something I personally have any
interest in, but then I've spent hours upon hours upon hours tracing from
NPE which is roughly comparable. FWIW (as the owner of the NPE scans) I
don't make any restriction on people tracing from my maps - not just because
I believe in open data, but also because I don't think I'd have the legal
right to even if I wanted. Broadly the same applies to why we're allowed to
trace from Yahoo imagery. "Non-copyrightable" doesn't mean "worthless"!

Yes, I'm sure you did. But what I was trying to say is that (IMO) the really
important bit is this:

Seriously - who is this "you"?!!!

There is no "you" in OSM. There's a big "us". It's an open source,
collaborative project. (I presume you can't mean the OSMF board in this
context as I'm not on it and haven't been for going on a year, as I'm sure
you checked on the OSMF website.)

I expect the OSMF people think they _have_ sorted out the "fundamental
issues". Similarly, Potlatch does everything that I would ever need and I
never open another mapping program.

But, amazingly, some people have a different view and use this strange thing
called JOSM. Their definition of the "fundamentals" of mapping aren't the
same. That's good. We have thousands of mappers, of course they'll think
differently. And this is doubly true of licensing, which is always going to
be the single most controversial area in this or any open-source project.

So "I want a very detailed answer", in your previous message, is the wrong
way to go about things. "In my view, this could be a problem. Could we do
_this_ to solve it?" is exactly the right way. Come and join in, it's fun.

[OSM-legal-talk] "A Creative Commons iCommons license"

2009-02-28 Thread Richard Fairhurst

CC-BY-SA says:

You may distribute, publicly display, publicly perform, or publicly

Could we ask CC to declare that the new fabulous ODbL, after due revision

licence for the purposes of the above - in much the same way as FSF
permitted migration from GFDL to CC-BY-SA?

I'd be interested to see this related to our userbase and editing stats.

If (say) we lose 5%, how many months - at current rates of growth - does it
take us to get back to the previous level?

And an alternative way of looking at it is: might we lose people if we stick
with CC-BY-SA? I suspect whatever decision is made, some people will leave;
the question is how long it takes us to recover.

No it doesn't, that's the entire point of what I said. (Is this the
five-minute argument or the full half-hour?) This is what 4.7 in ODbL is all
about. The data is still "protected", if that's the kind of language you

So now I am utterly confused.

Some people called Wilson Sonsini have advised us to use ODbL in a manner
which is not, AIUI, the manner recommended by the licence co-author, who one
would presume understands these things.

And here I am debating with an OSMF board member who appears to be arguing
_against_ the licence being recommended by OSMF.

What on earth is going on?

As you know (and without wanting to reopen Saturday's argument) I don't
believe that users are intended to sign up to the FIL. I believe that
they're intended to sign up to the ODbL, and that each user is viewed as
contributing a database of content to the wider OSM database, the individual
"atoms" of which are licensed as FIL to recognise that they are,
essentially, facts. (One could argue that, coincidentally, the changeset
model being adopted with 0.6 makes the conceptual leap to "database" very
easy indeed.)

Clearly from Saturday's postings you disagree. Nonetheless the very fact
that there is some uncertainty about this merits a clarification, ideally
both from Jordan and these Wilson Sonsini chaps.

Just to dispel any conspiracy theories: that certainly isn't true.

Looking at the postings to legal-talk in March so far, I see contributions
from three people I believe to be PD advocates (Frederik, Russ, me) and six
from people I believe to be share-alike advocates (Simon, Peter, Rob,
Oliver, Etienne, Ivan). I don't keep track of everyone's preferences - I'm

There's three categories to consider relating to existing data.

1. People who have made edits and can't be contacted. This is the hard one.
(As said previously, I think _minor_ contributors - whose work isn't
"substantial" - could be moved across automatically if they don't respond,
though still given the right to withdraw at a later time, but this isn't a
universally-held opinion.)

2. People who don't like ODbL and withdraw their data. _Assuming_ we can get
the bugs sorted in ODbL, and we can't take that for granted yet, this
percentage should be very small. I'm reminded of a participant at the SOTM
licence debate (I won't identify him, he can speak up if he wants) who spoke
fervently against PD - which of course isn't what's being proposed here -
but later said "I think if you moved to PD, I wouldn't withdraw my data, I
just wouldn't contribute any more". If that's the case for PD then surely he
wouldn't withdraw from a different share-alike/attribution licence.

3. Large organisations. I believe Canada has been done with the expectation
of a move anyway; the US is PD so no bother; it's immaterial to Yahoo. So
the issue is largely reassuring the original owners of the European imports.
IMO ODbL should always be better for them because of its "contribute back
the source of improvements" clause, which of course CC-BY-SA doesn't have:
so, AND (for example) are guaranteed access to all improvements based upon
their work. But this is probably an evangelism job for the foundation.

So all in all, if done right (and that's a big if), the amount of data we
lose _should_ be very small assuming that ODbL is deemed acceptable and the
bugs are ironed out.

There's then a second question: how does a licence move change future
contributions?

Much harder to measure, but my gut feeling is that because the licences are
both attribution/share-alike, the move will be largely neutral, maybe even
positive.

I know a bunch of people who haven't contributed significantly to OSM
because of CC-BY-SA, generally either because of unclarity ("I don't have
any confidence this will stand up, so I'm not contributing to something that
could easily be exploited") or the old derived work issue. For myself, I'm
spending every evening this week working on a detailed map of the
Chesterfield Canal and the surrounding area: data which I'd put into OSM
under ODbL, but which at present I do entirely standalone under Adobe
Illustrator, because of CC-BY-SA. This is a regular occurrence (our magazine
runs a detailed set of canal maps every month) and it frustrates me every
time.

But, on the other side, there will be a handful who genuinely prefer
CC-BY-SA, and we'll lose them.

Re: automatically moving from CC-BY-SA to ODbL via a licence upgrade: for
those who don't follow legal-talk, I raised the idea there in the
expectation that the nice chap from Creative Commons would respond, and sure
enough, he did. However, his reply was that CC's position is that data
should be licensed as public domain, so they wouldn't be interested in such
a move.

IMX it's a platform thing. Windows people genuinely do run their web

Us Mac people, by contrast, usually have about 57 different non-full screen

Goodness me, it must have been - Macs have been like this since at  
least System 7 in 1991ish...

Seriously, though, it does depend on the app. Right now I've got open  
TextEdit, Safari, TextMate, Cyberduck, Colloquy, Mail, Preview, and  
Terminal: the only ones I can imagine making any sense full-screen are  
possibly Mail and Terminal, and I don't think I've ever used either as  
such.

OS X, and System 7/8/9 before it, makes much heavier use of  
drag-and-drop between apps than Windows has ever done, and users are  
expected to think that way. (The classic Finder didn't have copy and  
paste for files, for example; it was assumed you'd drag from one  
window to another. It's only in OS X as a "borrowing" of the Windows  
paradigm.)

But Word and Excel borrow so much from Windows that they can make more  
sense full-screen, and the Adobe stuff is as ever a law unto itself -  
so many bloody floating palettes, one screen sometimes doesn't feel  
enough. (http://adobegripes.tumblr.com/ is brilliantly observed and  
puts all our parody blogs to shame.) And even Apple have been getting  
a bit too full-screen for my liking with some of the iLife apps.

Where was I?

If it helps, there _isn't_ anything going on behind the scenes... well, at

Vent. Rant. Anything from a misplaced capital in ODbL to a serious doubt

Far, far better that you speak up and post "I'm worried about this
because...", even in Schwabisch dialect if you like, than you sit there in
silence thinking "there's this conspiracy to make OSM commercial and I feel
left out". Because There Is No Cabal. Look around you - who's organised
enough to come up with a conspiracy? If there was a conspiracy they'd be
doing it better. But OSM is at heart a disorganised rabble - that's why the
communication on the licence issue has been shit, yes, but that's also why
we've mapped large portions of the world, because you couldn't organise it
better than that.

I've said it a million times before but: there is no "you" in this project,
there is only "us". Of course, this might be why Steve thinks I'm a filthy

I think this is a serious error in the ODbL draft 0.9. (I believe Frederik

That's not quite what I was thinking of - it was more the cartographic style
than the mechanics behind it.

The Osmarender layer tends to prioritise more POIs, more differentiation
among little details of OSM tagging, than the Mapnik one which is a very
focused "classic cartographical" approach - more so than most webmaps,
indeed, which is one of the reasons I like it so much. But certainly the
Osmarender layer is a fuller depiction of the breadth of our community.

So maybe
  "Classic style"
  "Community style"

would be clearer than a bald Classic/Community.

Sure.

A printed map; an online routing service (like, say, YOURS,
OpenRoutingService, or CloudMade routing); and a dedicated satnav device all
perform the same function: they communicate a subset of map data to the user
in an understandable, friendly way.

Under CC-BY-SA, as I'm sure you know, a printed map can only be licensed as
copyleft. The cartographer therefore no longer has exclusive rights to their
"added value" (colours, selection of data to include, and so on), which are
clearly apparent from the map. These can be trivially copied.

Under CC-BY-SA, a routing service does not have to be licensed as
copyleft.[1] The author of the routing service does not have to disclose
their "added value" (weightings for different types of road, any
transformations applied to the data, etc.). These cannot be trivially
copied: to do so would require reverse-engineering a near-infinite set of
requests and you'd probably be banned for DoSing before that. ;)

It's an artefact of the fact we're currently using a "creative works"
licence - the copyleft therefore applies to creative works. ODbL is a
database licence, therefore the copyleft applies to data. ODbL is not
interested either in art or in computer source code. The really good thing
is that OSM therefore gets [2] the "added value", the data, in
computer-readable form from both - something CC-BY-SA doesn't offer.

You could, of course, argue the opposite of ODbL - that the routing service
author should have to publish their added value in full, just as the
cartographer does - and indeed Lutz.horn on the wiki has said exactly that.
I think that would be a very honest position to take, and if you're the kind
of guy who believes everything should be Free in the RMS sense, I respect
your opinion though it's obviously not one I share. But I don't see how
arguing for full disclosure by cartographers, but not by routing system
authors, is tenable.

I think Rob Myers summed it up well on legal-talk:

"It's a pragmatic step to ensure that what users of free maps actually need
(free maps generated using quality geodata) isn't denied by ensuring that
the subject of copyleft in the wild is something else (low-resolution maps
rendered from that data)."

I think you're approaching that from a very programmatic perspective, and

No, no, no, no, no, no.

It might be easy to do an automated rendering. That's not what I'm talking
about. What concerns me is hand-drawn cartography. The "program code" for
that, in my case, is something like Inkscape or Adobe Illustrator, which
anyone can have - but that's incidental.

I spend days on getting the cartography right for the maps we produce in the
magazine every month. It isn't "rendering". It's entirely done by hand.
Getting the label placement right, choosing the colour set, working on the
pull-outs, generalising features so that they don't collide but the user
doesn't notice the distortion: that _is_ a great deal of effort. I try to
aspire to OS Landranger quality of cartography, not MapQuest!

http://www.systemeD.net/osm/caldon_2.jpg
http://www.systemeD.net/osm/caldon_3.jpg
http://www.systemeD.net/osm/caldon_4.jpg

(There's no OSM data in there - and conversely, OSM doesn't have all that
data either; and even if the maps were CC-BY-SA, which they weren't, the
generalisation is such that CC-BY-SA doesn't give much useful return to the
project.)

Believe me, I first wrote a passable routing program with reasonably decent
weighting at the age of 19 or so (heh, I found a review -
http://www.thecompclub.org.uk/newsletters/12.pdf), and it was a whole host
more trivial than the n years of experience that have, I hope, given me the
skills to design attractive maps.

So to return to the point you have completely ignored, can you tell me  
why you're happy that the (current) licence doesn't require routing  
program source code to be released, please?

Ok, that's consistent. Extreme, perhaps, but consistent. But:

is inordinately offensive.

As far as I know there are only two "OSM players" who are commercial
cartographers in some way (though for neither of us is it our main job): me
and Steve Chilton. To allege that we are aiming to take advantage of other
contributors is, yes, offensive, but also insane beyond belief. You might
not like Potlatch, you might not trace from NPE or ever use any traced data,
you might never use the Mapnik layer. But there is no denying that all three
of them are very major contributions to OSM without any - _any_ - payback.

Meanwhile, the guys releasing the routing software are, er, the ones who've
got €2.4m of venture capital. I don't begrudge them that - quite the
contrary. I don't think anyone does. But you might want to open your eyes.

Sheesh.

No. Not at all.

I don't know where this idea is coming from. ODbL does _not_ insist that the
data can only be accessed by open-source programs or in open formats.

A couple of people appear to have suggested that _their_ ideal licence would
require this; but given that a) they haven't actually proposed such a
licence, b) nor have they argued for the easy and obvious step of
browser-sniffing to prevent IE/Safari/Opera users from using osm.org (well,
exactly), I suggest said suggestions are politely ignored until they do.

> But don't kid yourselves it's a simple A or B choice.

Absolutely.

Steve actually answers this in his (very good IMO) "Licence to kill" post.
You can theoretically work out a complicated Boolean system of "is this
derived from an ODbL refusenik's work?". You can read every bit of
discussion about what "substantial" might mean in different jurisdictions,
and write some clever fuzzy-matching software to reflect that. I think
that's what people are talking about here.

But as Steve points out, that's a programmer's answer, all very
black-and-white. It doesn't actually work like that.

What really makes the difference, in my very limited understanding (but hey,
I'm a journalist not a programmer, limited understanding is a speciality :)
), is intent. Intent, and acting in good faith at all times. If we can
demonstrate that we've taken reasonable precautions; that we have removed
people's data on request (which, of course, we can do at any time); 


And for those who say "well, let's stick with the clean dataset we have
now":

We don't actually have a clean dataset. Nowhere near. We have material from
Google Maps in there. We have material from the Ordnance Survey. We may even
have entire countries which have been taken from a source not compatible
with our current licence - see the discussion about some of the ex-USSR
states.

The reason we haven't been sued is exactly the same. Intent and good faith.
Things like community pressure, the stuff in the FAQ, and the warning you
get when you start Potlatch. The efforts we go to to gather our own data.
That is real, hard proof. And that won't change - we should make real
efforts, and we will, but clinical boolean precision is a distraction.

(Ed asked how we'd "convince a court of law" - that's how. At the very
least, if Paul The Disaffected Mapper doesn't want to go to ODbL, some of
his stuff somehow remains in, and he says "ha, I'm going to sue", that
_very_ instant a crowd of OSMers would go and survey the place in question
to replace his data. You know what we're like. We like a challenge. :) )

I will quote the following from an Ordnance Survey agreement as much for

"Intellectual Property Rights means copyright, patent, trade

I have not made any of that up. Though I think Fake Ed Parsons put it more
succinctly:

"Not only do we own all your data, we also own your 
trademarks, your logo and your fucking pet cat. Thanks."

As ever with these things, either you join in on the arms race (which is why
ODbL has three prongs: copyright, database right, contract), or you put down

If it can't be edited, there's no point sending it to the editor. It would
only mean more bandwidth => slower editing. Therefore I would alter
amf_controller so that anything with immutable=yes wasn't sent to Potlatch.

(At which point most of Germany would tag their towns immutable=yes... but I
digress. :) )

So what's the point of having it there? I presume so that people can get it
via the OSM API and via planet dumps (you've said as much in another post:
"consistent metadata and a consistent single-source API").

To me, this is another argument for good libraries in popular scripting
languages, not for putting it in OSM. If I could do a call from Perl or
ActionScript or Ruby whatever to say "get all geodata within this bbox from
openstreetmap.org, and also freesurveyorsstuff.org, and return it in one
object", that would fulfil the need - without bending OSM to do something it
was never intended to do.

We do have all that, of course. It's called, for OSM-historical reasons, the
Rails port. You can get yourself a server (I can probably think of people
who will lend you one); install the Rails port on it; and upload this funky
DEC stuff to it.

People can then access it using exactly the same language/currency/interface
that they're used to with OSM. Hell, if you think having to call two URLs is
too much like hard work, you can augment your data with minutely-updated OSM
dumps, and make everything available from that one place. Given that (AIUI)
you don't think people should edit the DEC data, there won't be any syncing
problems between your server and OSM.

Oooh, and it's the proposed NCN 57 too. (Though I expect NCN 57 might
actually end up going a different way, at least at first.)

Clearly the fact that it's officially a bridleway is worth recording,
because it implies all sorts of useful legal permissions and stuff. Yet
clearly most users will actually use it as a cycleway, because there are
more bikes in Oxford than horses.

So three roughly equivalent suggestions:

1. highway=bridleway, surface=paved
2. highway=cycleway, designation=bridleway
3. create two parallel ways: tag one of them as above, and the other as
highway=bridleway, surface=something_that_implies_mud. Potlatch can do this
for you with its parallel way feature (Other Editors Are Available).

Sort of. There are actually two fairly important exceptions to the  
bridleway > cycleway rule (this is getting a bit UK rights-of-way  
geeky, sorry everyone).

A bridleway is available to cyclists but there is no obligation on the  
land-owner to maintain it for cyclists. Cyclists are also required to  
give way to other users.

http://www.ctc.org.uk/DesktopDefault.aspx?TabID=4678
http://www.sustrans.org.uk/webfiles/Info%20sheets/ff27.pdf

A "cycle track", however (as declared by a Cycle Tracks Order) confers  
an obligation on the local highway authority to maintain it for  
cyclists. As best as I can see, there is no formally expressed  
priority of use. So in this case cycleway actually > bridleway.

This is kind of what I like about the designation= tag. The Oxford  
example is maintained by the local highway authority as a cycleway. So  
it quacks like a cycleway, looks like a cycleway, but is legally a...  
bridleway. highway=cycleway, designation=bridleway sums this up  
concisely.

Thanks for putting words into my mouth. Clearly I'm not.

"mainly/exclusively" is the difference. Access permissions cascade down[1].
We grew out of tagging
highway=secondary;motorcar=yes;foot=yes;horse=yes;motorcycle=yes;bicycle=yes;penguin_on_a_skateboard=yes
about three years ago - people were starting to take the piss
(http://mappinghacks.com/2006/09/18/have-a-nice-metadata/).

So why on earth you think that highway=cycleway;foot=yes is still required,
I have no idea. Unless, of course, you do actually go around tagging
highway=secondary;motorcar=yes;foot=yes etc. etc., in which case full marks
for consistency albeit no marks for clue.

But, you know, well done on finally uploading some GPS tracks in the last
few weeks (http://www.openstreetmap.org/user/Hawke/traces). Maybe actually
doing some mapping will give your opinions some weight, rather than just
being another tedious wikignome. We live in hope.

[OSM-talk] OSM in Living Spain magazine

2009-04-07 Thread Richard Fairhurst
Living Spain, a quarterly magazine published by our company, has just  
published its new spring issue and I'm pleased to report that it  
includes OSM mapping for the first time.

The magazine contains pull-out "Instant Guides" to Barcelona and  
Torrevieja, and each one has a city map. For these, we've used OSM  
maps, using the default Mapnik rendering - properly attributed, of  
course!

Big thanks to the Spanish community for the mapping and, of course, to  
Steve Chilton for the cartography.

The magazine will be on sale in the UK in a week or so; I'd be happy  
to post a couple of copies out to the Spanish community if anyone  
wants to give me a postal address.

Database right, on the other hand... ;)

For a magazine, I use
"OpenStreetMap.org and contributors: CC-BY-SA"
next to the map.

Then in the flannel panel at the start of the magazine (where
copyright/contributor information usually resides, we add something like
"Where an image includes a credit similar to CC-BY-SA, it is made
available under that Creative Commons licence: full details at
www.creativecommons.org."

Mapnik export doesn't work on Wednesdays while the database is reloaded. I

Indeed, there's no prohibition on empty changesets. Specifically, Potlatch
at present creates a new changeset when you open it, so if you don't
actually make any edits then an empty changeset will result. I'd like to fix
this so it only creates a changeset on your first edit, but it's not
critical.

Load-related.

I know of two issues with Potlatch 0.11 at the moment. One is relation
handling (actually I see Ed's just posted about that) - not clear yet
whether this is Potlatch-specific. The other is that there seems to be some
issue with junction nodes which is causing a server error dialogue to come
up, haven't narrowed this one down yet.

Still trying to track this one down. It works 100% as intended on my local
test setup, with the latest svn code and the latest Potlatch (though still
running MySQL rather than Postgres). The bug only appears on the live site.

Fixed (hopefully) and committed. Will be live later when Tom has a chance to
deploy it.

For those interested, the database was changed in 0.6 to store relation
members as 'Way', 'Node' or 'Relation'. Previously they were stored as
'way', 'node' and 'relation' (I've now updated the wiki documentation to say
this), and Potlatch was still expecting that.

You are very charitable, Frederik (well, maybe not to those of us who you've

whether he should import them to OSM, and we replied no. To that question,
nothing else. He also asked "so I should remove them from Wikipedia?" (or
something along those lines) and was told that #osm has no power over, or
indeed interest in, Wikipedia.

Why he, or you, or anyone should take comments in #osm to mean "oh, you
should do this in Wikipedia" without even questioning it or - heavens above
- asking some Wikipedia people, I don't know.

Yeah, but by "you guys" you actually mean Europe, and in particular, the UK.
I mean, your paragraph above makes absolute sense for someone who knows a
bit about the US legal framework and US legal history. I could read Feist vs
Rural and Mason vs Montgomery Data and say exactly the same thing.

The trouble is that I'm sitting in a stone cottage in a quiet Cotswold
country town opposite a pub serving five real ciders and a comfortable
hourly InterCity to Lond

- scratch that -

The trouble is that I'm sitting in England and it doesn't, frankly, apply to
me or my compatriots. We don't have Feist vs Rural, we have Ordnance Survey
vs the Automobile Association and all your "act of creation" stuff means,
really, bugger all here. We have the sweat-of-the-brow doctrine instead. It
sucks harder than a Hoover, but it's there.

So there are three important OSM principles here.

One is that we are whiter than white - that's what we're here for. We don't
push the legal envelope. If someone else wants to, that's fine. But we don't
want to be the test case. I strongly suspect, though I stand to be
contradicted, that CloudMade doesn't want us to be the test case either.

The second is that we have the manpower of crowdsourcing (and the power of
Greyskull). Yeah, we could import a few dozen POIs from Wikipedia. Oh joy.
Alternatively we could get our 100,000 mappers to map them themselves. I
suppose, worst case scenario, it might take up to a month.

The third, of course, is that anything decided without community consensus
(cf Cyprus edit war) risks unleashing a bot arms race.

Sweat-of-the-brow doesn't mean that. It doesn't mean that "A did some work,

No. If you tell me (or, by extension, the OSM community) publicly, or I
notice, I _will_ look. I will not close my eyes. If it looks suspicious I'll
raise it on the lists.

You don't need Easter eggs to spot infringement. For example, there is
someone on this list who figured out, correctly, the copyrighted source from
which People's Map got their road numbers. I'll let her speak for herself if
she wants to.

Russ Nelson wrote:

Google's imagery suppliers collected and rectified the imagery. "For over a
hundred years, English courts have held that a significant expenditure of
labour is sufficient" - that's, er, Wikipedia saying that. If they'd
rectified them differently, your 14 digits would be different.

Now I'm not saying that this is necessarily a view I wholly subscribe to (if
you could actually be bothered to look through the wiki and the 8zn prior
mailing list discussions, you'd see I've put stuff on there with a more
liberal view of this). Clearly some people don't - Yahoo, for example.

But Ivan has it right. Google's imagery suppliers could well take that view
if they wanted to, and OSM's attitude has always been "we are whiter than
white". Don't forget we have _expressly_ asked Google, in the form of Ed
Parsons at SOTM, and he has _expressly_ said, sorry, no, we don't have those
rights to give away.

Yet... we're forgetting something:

> To think that Google has ANY copyright ownership of points chosen 
> off their aerial photographs simply boggles the mind.

Er, how come we're suddenly just talking about aerial imagery?

The Wikipedia page I quoted says "Google Maps". It actually recommends you
use their API and their geocoder, too: that looks to be against their ToS to
me, though I'm sure you'll find some way to disagree.

It even provides a handy tool for you to do it.
http://pagesperso-orange.fr/universimmedia/geo/loc.htm . That _directly_
extracts from their geocoder. Nothing about clicking on imagery there; I
type in my address and it gives me a lat and long. Wikipedia also recommends
you do a web search for the city name together with "latitude" and
"longitude" so, hey, why stop at Google? You can infringe on lots of other
people's content, too!

With all that in mind, I reckon any court would conclude that it is very
likely there has been large-scale extraction of features. 

But evidently I'm being an armchair lawyer:

> But nobody wants to talk about the hard stuff.  Everybody just 
> wants to be an armchair lawyer rather than exercize their brain. 

Oh, don't be so patronising. And you're not? Please.

Actually, I think an OSMer said it best on Twitter.

"Openstreetmap is about gathering map data and sharing it. Some people seem
desperate to import data from anywhere. GATHER IT YOURSELF."

And with that, I shall stop posting the same old stuff that's been said so
many times before, and go and gather some data. I recommend it. :)

I suggest you ask your bosses. Show them what you're proposing to import.
Show them the Wikipedia page that explains how it's been gathered.  Ask them
if they'd be happy with that in their dataset and are prepared to run the
legal risk. I'd be interested to know their response.

[OSM-talk] Potlatch 1.0

2009-05-21 Thread Richard Fairhurst
Hi all,

It's been an important 24 hours for the webmapping world. At last -  
and after many months of expectation - UK cycle charity Sustrans  
released their new online slippy map. Oh yeah, and some irritating US  
outfit did some data API or something.

But never mind any of that, because it's also Potlatch's second  
birthday!

And that means: it's time for Potlatch 1.0.

What's new? Online help. Offline editing. Conflict management. A new  
way of showing junction nodes. Better changeset handling. And some  
other stuff.

Bugs and comments? Trac, of course, but there's also a new potlatch- 
dev mailing list - both for current Potlatch and exciting future  
stuff. Subscribe: http://lists.openstreetmap.org/pipermail/potlatch- 
dev/ .

Enjoy!

Entering non-ASCII text (e.g. é î å ë) works fine for me here, using Safari
4 on OS X 10.4. I think we'd have heard by now if there was a universal
problem!

Though I wouldn't know Kotoeri from Coco the clown, I've just played around
for five minutes, enabled it in System Preferences -> International, and
have managed to successfully select the Hiragana and Katakana entries from
the input menu while using Potlatch. The Kana palette then allows me to
enter characters - not the ones I'd expect, but this is probably because
I've started the browser with en-GB as the language and Flash Player tends
to be sensitive to that.

There's a new mailing list called potlatch-dev where such issues are best
discussed. :)

You can revert a way to an earlier version yourself, using Potlatch's

We send the magazine to the printers as PDFs, _but_ we always embed the maps
into each page as high-resolution TIFFs (i.e. non-lossy) - usually 300dpi
CMYK.

The big advantage of doing it this way is that you avoid any font (or other)
embedding problems. The alternative is to convert the text to outlines
before saving it in your vector format of choice (PDF/EPS/Illustrator),
which also works well. In theory you can embed the fonts in the PDF if the
font permissions are ok, but generally you only find out that this hasn't
worked once 25,000 copies have come back from the printers.

If you pick up a copy of the Waterways World Annual 2009 (for which someone
else did the maps, not me) you'll see we have a map of the Broads without
any rivers on it. :|

Because I don't really keep up with the ever-changing tagging discussions -
life's too short. Anyone with svn access can augment the Potlatch
preset/autocomplete files, they're all in easy-to-understand text:

http://trac.openstreetmap.org/browser/sites/rails_port/config/potlatch/

I do however reserve the right, should you add smoothness=very_horrible, to
remove it again, and additionally to come round to your house and kill you.

FWIW I personally think highway=road is not generally of much use in 90% of
cases. Whether you're tracing from Yahoo or NPE or whatever, you can very
often work out what highway value the road should have. Certainly, if it
were to be added to the preset menu, it'd need to be with a very clear
description of what it's intended for - "road, unsure of type" or something
like that.

Re: [OSM-talk] tagging "unofficial" cycle routes

If they're not "on the ground" (i.e. signposted), then adding them to OSM is
getting perilously close to tagging-my-favourite-road territory - so I'd
hesitate before actually tagging them. By the same token, we don't tag CTC
routes (a national cyclists' organisation) in the UK, which aren't
signposted, but we do tag Sustrans ones, which are.

Two things spring to mind.

One is that (presumably) these routes have been chosen because of objective
factors - decent surface, low traffic, that sort of thing. This can all be
tagged. Then anyone is free to benefit from this knowledge by using a
cycling route-planner on the data.

Secondly, this is really prime mash-up territory, but the great flaw of the
traditional (Google Maps-like) mashup approach is that it doesn't interact
with the data in any way. It's just a bunch of pushpins and squiggly lines
sketched on top.

There is an opportunity for someone to write, even just as a proof of
concept, a mashup that actually links to the data. You can't easily do
"follow way 827364 then way 76354 then way 9876325", because way ids change
as people edit the data. But you _could_ do "follow unclassified road west
from Chadlington to Sarsden, then follow unclassified road south to the
B4450" - something that can be recreated on OSM data. The CloudMade routing
API might be suitable for this: effectively you'd be storing the route as a
set of instructions to the routing API, with sufficient 'via' points to make
sure the right route was returned.

I don't dispute that this information would be valuable - to draw a
cartographic analogy, that's absolutely what Michelin maps do, though the
fact they're the only ones in the UK to do so might tell you something!

But nonetheless the existing use of the highway= tag in the UK is understood
by 95% of UK mappers and it's not helpful to have a little island of "we do
things differently here" in Ipswich. So you should (I would almost go as far
as to say "must") use another tag for this. Personally, I would love to see
the use of tags like traffic=low - it would be hugely useful for determining
cyclable roads.

More generally, over the next year, we're going to be seeing a lot more
custom rendering (a la CM Style Editor), on-the-fly rendering (see Cartagen
and Potlatch 2), and configurable routing engines (everywhere). So the
barrier against having a new tag is much, much less. "Tagging for the
renderers" basically isn't needed any more: you use the tag you want and the
client that responds to it.

Followups on the UK-specific point to talk-gb, I suspect.

I live in Charl_bury_ and spend a lot of time in _Bur_ton. Shaun, however,

They're all the same root. I'm not sure that the existence of one of them in

Presume that's Melbourne, Australia rather than the nice little Derbyshire
town ten miles down the road from where I am now. :) But yes, I can go to
Melbourne and see that way 4308541 (for example) is 'partial'. It could be
that your Flash Player has cached a faulty crossdomain.xml and is
therefore refusing to load, or something. I'd try manually opening (and
reloading) wtfe's crossdomain in a browser window to refresh the cache, or
experimenting with a different browser to see if that works.

Agreed.

OSM is not the world's sole repository of co-ordinate data, and nor should
it be. This would be much better stored in an externally hosted .osm file or
shapefile, which can be loaded into the editor/tool of your choice, than in
the main database.

We tag what's on the ground, whether it's route signage, cycle-specific

Are you suggesting a deviation from that?
