I presume that you used a city-extract, and that you have your plans
for keeping up to date or not.

Have you considered,
* Reload the same database but with a regional or larger extract?
* Load a second database with a larger regional extract?

The steps will be the same, but the waiting periods will be longer.
Have a look at the benchmarks page on the wiki[1] to see how long a
full planet import takes on various hardware.

Re: [OSM-dev] Looking for OSM Licensing Clarification

[Richard Weait]

The OpenStreetMap license ODbL is what is known as a Share Alike
license.  In that class of licenses, one is granted more permissions
when one shares and shares alike.  If, on the other hand, one wishes
to keep things for ones exclusive benefit, ones permissions are more
limited, perhaps even to a null set.

Again, in very broad terms, one has more freedom if one uses the
OpenStreetMap data without changing it.  Combining OpenStreetMap data
with other non-OpenStreetMap data sets, is an area where the
obligations to share are deliberately strong.

The details matter in this subject area, and it is a benefit for you
to understand your obligations from the start.  Please consider giving
more details and holding further discussion on the legal-talk@ mailing
list[1], which is the ideal location for this topic.

Hi Samat,

There is a shape file version of that data available from Geofabrik as
well as the .osm file you have.  Have you tried it?  Link below.

http://download.geofabrik.de/europe/hungary-latest.shp.zip

Also, if that file doesn't do exactly what you want, Geofabrik offers
custom shapefiles as a paid service, if I understand correctly.

Grant, thanks always to you and to the full admin team, for making
OpenStreetMap work and work well.  I appreciate your constant
attention to the nitty bits and the gritty bits of OpenStreetMap
infrastructure, keeping everything up and running.  The way that you
make frequent improvements and additions to OpenStreetMap Foundation
services is wonderful.  Your immediate attention and rapid response to
unscheduled events is exemplary.

Thanks so much.  You admins should be paid in more than just thanks.
Not just for your continued expertise, but for the ten years of

There are several ways to get up-to-date OpenStreetMap data.  Please
tell us approximately what is your bounding box / area of interest,

Dear Tac,

What did Google say when you asked them?  And what did your lawyer say?

That quote from 2(g) seems pretty clear. ~"Don't do it."  If you want to
argue that, ~"Don't do it" doesn't apply because of a special condition in
your case; well, then you are making that argument.  But that would be an
argument.  Perhaps a legal argument.  Perhaps an expensive legal argument.
:-)

>From an abundance of caution, I'd not use the Google software for the
purposes of OpenStreetMap, without the consent of Google (and OSMF).  But
that's me.  So why don't you ask them?

If I remember correctly, several OpenStreetMap contributors have built
their own similar camera rigs in past.  Why not join your experiences with
theirs, contribute to their Open Source efforts and build a completely open
stack?  You could still sell your hardware into that market after helping
to launch that market with an open stack.

afternoon at Ryerson.  Details to follow.

Also as last year, there will be a ton of socializing and meeting and
greeting with the local OSM community, Friday night and Saturday night.

Last year, attendees travelled to Toronto from England, The Netherlands,
USA and even the Toronto suburbs.  Join the fun!  See you in Toronto.

[OSM-dev] baseball cards, user stats and multiple accounts

[Richard Weait]

I've been interested in the statistical aspects of mapping for a
while, and in baseball cards for even longer than that.

You may have seen this before.  Hang on.  I've added something cool.

One question I come back to frequently is "If mappers had baseball
cards, what would they look like?"  Another is, "If you had mapper
baseball cards, who would you trade for whom? "  That is probably a
topic for another day.  :-)

For today, I've made some updates to my little mapper baseball card
project. I imaginatively call it "UserStat" because I am Just That
Good At Marketing.

So here is a basic mapper baseball card for "rw__".  Hey@  That's me!

http://rweait.dev.openstreetmap.org/daily/rw__.html

Now, that won't win any design prizes, but I'm trying to keep the html
simple and sane so that a Read Designer can come along with some nice
css to make it really rock.

Here's something I didn't know.  I used Potlatch more than JOSM in
only one year.  Hmmm.  I would never have known without the stats and
little graphs.

That's cool, I guess, but I have another account as well, 'rw_'.
Again.  Note the awesome imaginative name.  Here's the card for that
account.

http://rweait.dev.openstreetmap.org/daily/rw_.html

There is something different to learn here.  I didn't use the account
for a couple of years.  And I hadn't used it with Potlatch at all.
That probably speaks to my browser settings in some way.

Here's something new.  What if you could get combined stats for all of
your specialty accounts?  What would all of that combined mapping look
like if it were a single mapper?  Let's find out.  Here are my three
accounts with combined statistics.

http://rweait.dev.openstreetmap.org/daily/rw__career.html

The code is all available in UserStat, the examples are from the
rearrange branch.  Hopefully I'll merge it shortly and move towards a
0.1 release.  You'll want ChangesetMD as well, as that builds the
database the UserStat relies upon.

https://github.com/rweait/UserStat/tree/rearrange

My wishlist:
- mappers to think it's cool and ask for their stats.
- designers to take an interest in making it prettier.
- developers to patch and improve.
- ideas!  What are additional tools that mappers use and how can we
measure them?
- long range: make it all "webby and stuff" and let people serve themselves.

Best regards and happy mapping,
Richard

[OSM-dev] Mapnik Code Sprint - Be there!

[Richard Weait]

Dear All,

Twenty months in the making.  The next hugely successful and awesomely
fun Mapnik Code Sprint will be held in Washington DC, in just a few
short weeks.  Perhaps you should be there!

Some details.
https://github.com/mapnik/mapnik/wiki/Code-sprint

Who should be there?

You should be there.  Are you worried that the activities will be
"over your head"?  Maybe, but you can self-test.  If you have ever
committed code to Mapnik, or submitted a patch that was accepted then
you should be there.  Are you an expert-level user of Mapnik, with an
interest in improving it for others?  Are you a documenter of code, a
writer of tutorials a hunter / squisher of bugs?  You should be there.
 Are you an expert cartographer?  You should be there.  Do you have
bits and pieces of these skills and have thought to yourself, "I bet I
could improve Mapnik if only I did ..."?  Then you should be there.
If you already follow the Mapnik group / list, you should be there.

Why should I be there?

You should be there to make Mapnik better.  We will be fixing bugs and
adding capabilities, we'll be improving documentation and adding
tutorials, we'll be learning from each other and working together.
We'll be making the path to Mapnik success easier for those who follow
us.

We'll be having a wonderful time while we do it.

You should be there.

Still have questions about whether you belong and will be welcome?
Join the #mapnik IRC channel on freenode and talk to us about it.

Like the previous code sprint in London in 2010, we'll have a Meet &
Greet on Friday night.  We'll learn about the hope and dreams and
skills and goals of each other.  We'll exchange stories and get to
know each other without the computers in the way.

Saturday, we'll start with a brainstorming session to share our short
term goals for the weekend, then we'll start coding in earnest.

Sunday, the coding will continue, punctuated by periodic exclamations
of, "Awesome!  You have to see this!"

Add yourself and your tasks / goals to the wiki.
https://github.com/mapnik/mapnik/wiki/Code-sprint

Now.  Talk about how much fun you are going to have when you come the
the code sprint.

See you in DC,
Richard

The API went back to normal, read - write operation a few hours ago.
Either on schedule or slightly ahead of schedule. :-)

By popular demand for mappers, minutely diffs will be provided during
this transitional period.  They will be unusual[1] so evaluate
carefully if you want to consume these diffs or not.

There will be another change to the ODbL diffs, at the completion of
the license upgrade.  The same caution to evaluate when you wish to
transition to the new or the ODbL diffs holds.

[1] They'll include changes by the background cleaning script so the
diffs will be larger than usual.

Andrew provided a great venue, and plenty of coffee to keep the coders
fuelled.  We had just a few too many people for the big room on
Saturday at one point and we also had plenty of breakout rooms.  I
think it speaks to the quality of the event that we had available
space to spread out, but nobody wanted to do that; we chose to stay in
the big group rather than risk missing anything.

And thanks to all of the attendees.  I enjoyed meeting some faces to
go with the names and 'nicks' I know from email and irc.  Several
others were meeting for the first time as well.

So what, specifically happened?  More of that will come out over the
next little while.  I'm sure others will talk about the details of
their code and projects.  In general terms here is what I say at
various times.

The schedule was deliberately loose.  It was planned, based on the
successful London Hack Weekend model, to be open to serendipity.  A
sort of technical Petri dish, where things can grow.

At various times, these are the types of things I observed:
- participants sharing, discussing, advising and admiring.
- a group discussion about a "big picture" thing to do with a portion
of the OSM web site.
- participants posed around a laptop to observe a demonstration or
answer a question.
- an individual talking about an idea to a group.
- peer coaching on languages / environments.
- distinct small groups working on collective projects.
- gathering consensus on what to have for lunch.
- sequenced orders to various lunch spots.
- periods of silent independent productivity.
- things mocked-up; things demonstrated, things committed to VCS.

I had a couple of things in mind to keep myself busy at the Hack
Weekend.  Stats and shields.  I did get something done with stats, but
less than I had hoped.  I don't feel cheated by that; in place of
independent work I was able to enjoy the group participation.  I
didn't 'do' anything with highway shields but I did talk about them
and a couple of other participants took an interest and actually did
something with them.  I'm really excited about that.  And then, with
time running out on Sunday, another participant reminded my of the
golf rendering layer I did a while ago.  So I messed with that a bit
too.

Now, after a full weekend of OSM-related technical stuff, I feel
inspired to do even more OSM-related technical stuff.  And I feel that
I have stronger connections with some of the other participants and
learned things from them that will help me to do more than I could
have done had I not attended.

Best regards,
Richard

[OSM-dev] Toronto Hack Weekend

[Richard Weait]

Dear All,

The Toronto Hack Weekend[1] is shaping up nicely for mid-March.  You
can see that some have registered already on the wiki page.  I have
verbal confirmation from three others who are each flying in for the
event.  There will certainly be more.  It is critically important to
the event organizers that you RSVP early.

I have a potential venue sponsor who will make the event even better.
I hope to confirm and announce those details this week.

I would welcome, in addition to the venue sponsor, additional sponsors
to help defray the travel costs for those visiting Toronto for the
event, and / or for contributions to defray the food and beverage
costs.

If you find Toronto to be "too far from the US East Coast" for your
preference or too far in the future, remember that the DC Hack Weekend
(Arlington VA) is this weekend.  Don't miss it.

Best regards,
Richard

I have a counter question.  If rendering surface is so important to
some users, why have they not rendered it themselves?  The database is
provided.  The tools are provided.  Even an interested, enthusiastic
and clever community is provided.

Why must the "problem" of rendering surface tags be solved on a
specific rendered layer or service?

Was not OCM first created by a small, interested community, without
"official" support?

Come on.  Do it!  Render surface values.  It will be wonderful and

Re: [OSM-dev] Something wrong with the renderer?

[Richard Weait]

If you have a look at the rendering queue graph on yevaud, you'll see
that the rendering load has increased dramatically since the beginning
of 2011.

http://munin.openstreetmap.org/openstreetmap/yevaud.openstreetmap/renderd_queue.html

Often, those scraping the tile that they will likely never view do not
understand that they are causing an unreasonable load on OpenStreetMap
resources.  That load is already affecting mappers, as indicated by
Manuel's query to this list.  If unchecked, this abuse of
resources-for-mappers by consumers-of-maps, would be Very Bad for OSM.
 And then, bad for those map consumers too, obviously.

The admin team is working on technical responses to reduce the impact
of irresponsible consumers, without harming mappers.  Your
suggestions, working examples and patches are, I'm certain, welcome.
The discussion on #osm-dev around this topic is often lively.

There is a social component to this as well.  Some of the application
developers have been responsive when advised of their impact on OSM
resources, and moved to more-responsible use of our resources.  This
response varies but can include building their own tile server, or
sourcing OSM tiles from other servers.

If you know of an application that consumes OSM tiles, you can help by
advising them of the tile usage policy, and guiding them to
responsible use of our resources.

We're all playing the the same OSM sandbox here.  Fortunately we can
each have our private sandboxes as well as all the tools are Free and
Open.

> I'd much rather my work be put to some use.

I'd much rather you join and participate in the community on a
continuing basis by learning and sharing.  That may not be cards now,
as you have a deadline and a lot to do for your project.  That's cool.
 Having your own private database is the quick way for you to proceed.

Were you to build your 'bot make your changes, graduate and never
touch OpenStreetMap again, well that would look like you were treating
OSM as a litterbox rather than a sandbox.  You would be leaving the
community behind you wondering where all the new routes came from,
whether they were good or bad.  Any unexpected lump in a sandbox is
examined with initial suspicion.  'Bots make lumps everywhere.

Excellent.  You'll be in-scope on your local copy of the database as

It's a first go at a simple visualization.  We'll get better at it,
and the raw data will be published so that those with the motivation
can build their own visualizations.

So, no, it's not misleading.

As I understand it that graphic represents all accounts, including
bots, and rectangular areas are proportional to the square-root of the
total number of edits per account.  The square-root was chosen because
the linear proportion or the largest contributors swamped the
following contributors even more.

But hey, that was a week ago, and more contributors have accepted
since that image was made.  So take it as a preliminary data point.
And the raw data will be available soonish so we can all draw our own
graphs and charts.

Dear Michael,

Thank you for getting me on the right track in our off-line conversation.

I think this project shows a lot of potential and I'm very pleased to
see what you have done with it.

Can you share with us, your plans regarding this project at the
completion of GSoC 2010?  I hope that you will find a wonderful

Perhaps your initial browser compatibility work will make it easier

Well perhaps you _shouldn't_ do it.  Comparing OSM to Gmap might be
interesting in some ways, but deriving data from one to the other is
certainly a bad idea, frowned upon by fans of either or both.

But it can be done.  There are OpenLayers examples that can show the

Hello Aditya,

While our documentation may be sparse in places, tagging is free-form
so extensions and improvements to tagging for POI and anything else is
unrestricted.  That said, OSM as a community has a substantial
investment in existing tools, interfaces and habits.

Regarding community building in India, I see that there is an OSM list
for India here: http://lists.openstreetmap.org/listinfo/talk-in
While folks on the dev list are interested in community building, you
may find a larger audience for the discussion on talk, and or newbies.

Any developer wishing to use OpenStreetMap tile servers for their
application, regardless of the language, should be aware of the tile
usage policy linked below.  OSM encourages you to provide your own
tiles so that you can take full advantage of OSM data and tool chain
without loading our servers unnecessarily.  It's easy enough to build
your own tile server.

If only there were some model for these museum enthusiasts to follow.
Some model of interested parties curating information for the good of
the community.  Perhaps refining the information and presenting it in
ways that attract the attention of the general public.  Or perhaps
carving away some layers of the information to show some interesting
underlying structure that would not be immediately apparent to a
non-expert.

Oh!  That model could be a museum curator!  Except in OpenStreetMap,
the curators neither lock the doors nor place the exhibits behind
glass boxes and velvet ropes.

Yes.  Sometimes the surrounding area is interesting for context.

Here is an example of osmosis making several extracts with polygons.

Perhaps you will decide that the tracks are not worth contributing.

If not:
- there is a josm plugin that allows you to edit gpx tracks to remove
your selected areas before uploading the track.
- gpsbabel offers options to remove trackpoints within radius,
boundingbox and arbitrary shape(I think)

Your donor could do this and edit OSM as well.  He'll have context
from his direct experience that nobody else might be able to extract
from his track files.  Importing data is cool.  Creating new mappers
is better.

[OSM-dev] Importing Canada

I'm importing GeoBase / Canvec data for parts of Canada.  Today was
the streams file for NTS 040p09 (Guelph, Ontario).  29,000 changes and
about ten hours to upload from josm.  Would it be acceptable to do

Dear Cornelius,

I had a similar problem recently.  Updating

mapnik

for svn.openstreetmap.org,
and mapnik from
svn.mapnik.org (sp?)

then re-importing my bounding box fixed it.  This is not the finesse

Vincent is correct.  Those calculations will help as a rule of thumb.

Back before I had to tell you kids to get off my lawn, everybody used
35mm film and dimensions were set in stone.  43.3, 36, 24.  We had it
all memorized, then those wacky CCDs came along with their 2/3"-format
and 1/2"-format in which none of the dimensions are actually the
dimension for which the format is named.  Oh, those were heady days.
Slide rules and drafting tables for everyone!  But you kids these
days, you know better, with your CCDs and your CMOS sensors and your
varying aspect ratios.  The old rules of thumb are likely to break
your brain.  So go to first principles and get off my lawn.

Ideally, you'll find the actual dimensions of the camera sensor in
your device.  This can be hard to find.  "N95", you say?  I see links
that suggest a CMOS sensor of 2582x1944 pixels[1].  Kodak has a
similar 5MP CMOS device with 2592x1944 and 2.2 micron (square) pixels.
 Other manufacturers may vary in ways that matter to you on the
details.  Find the real sensor data sheet if you can.

http://www.kodak.com/global/en/business/ISS/Products/DiscontinuedProducts/index.jhtml

Sensor width: 2592 x 2.2 microns = 5.7024mm
Sensor height: 1944 x 2.2 microns = 4.2768mm
Focal length: 5.6 mm[1]

Tan(angle/2)=size of film/(2*focal)

aFOV(h)=  14.28 degrees, thank you Wolfram Alpha
aFOV(v)=  10.81 degrees

But this is still an approximation, and based on an ideal lens with no
aberrations. It should get you started. ;-)

Best regards,
Richard

Hi Sam,

See http://www.weait.com/content/build-your-own-openstreetmap-server
Especially 

"Mapnik from source
Use Mapnik for rendering pretty maps. We'll use both the mapnik.org
project and some OpenStreetMap.org mapnik-tools and we'll call them both
Mapnik at various times depending on context. Sorry about that. This
section deals with the Mapnik.org project. "

And complete those steps down to "sudo ldconfig"  

If you can run all of those steps without error, try again to generate
z0.

Change the "5" above to "17" would do it.  But chances are that you
don't want to pre-build every tile for every location.  That would be a
lot of empty ocean tiles.  You'll be rendering for a long time.

Dear Soua,

If you want to run a local version of OSM you should look at this page
on the wiki.

http://wiki.openstreetmap.org/wiki/The_Rails_Port

Once you have your local rails port running you can import this file

or from a current planet file to populate your local API.  

Be aware that the real API will be updated from v0.5 to v0.6 very soon.
