[OSM-dev] generate shapefiles

Hi!
How do I generate an ESRI shapefile from the OSM data?
I wish to supply a polygon or rectangle and get back the shapefile for
that area...

Is there any script I can use for this?

Thanks and
Regards,
  Andreas Weller

Don't let your mind wander -- it's too little to be let out alone.

There is no service that does that for you. You have to download the OSM 
data - either a small section through the Export tab or a large section 
through OSMXAPI or by getting an exerpt from somewhere - and then run 
software on it.

The c++ program has already been mentioned. There's also a ruby 
implementation (see the "Export" section on http://osmlib.rubyforge.org/).

You can download ready-made shapefiles for certain areas from 
download.cloudmade.com (lots of countries) or download.geofabrik.de 
(some continents, some countries, and some administrative subdivisions 
in .fr,.uk,.de). Both providers use different structures and select 
different features for their shapefiles.

[OSM-dev] Adding support for relations to change_tags.py and other stuff

(CC-ing to OSM-dev in case anyone else finds this interesting)

Background: I've been looking for some sort of XML-SAX-like engine to
do massive changes to OSM data so that I can do mass-edits without
writing all the tedious parsing/upload/diff logic myself.

change_tags.py looks perfect for this with a few caveats, some of
which have patches & suggestions for:

Firstly it doesn't handle relations, in the attached patch I've
implemented support for this which seems to work, except:

* The Nodes/Ways/Relations count doesn't seem to work.

This appears to be due to some race condition in the XML parser I
can't find, if I change the counting code around line 300 to this:

        if name in ['node', 'way', 'relation', 'tag']:
            if name == 'relation':
                print "Read relation"
            self.read[name] += 1

And run this command:

PYTHONPATH=. python
~/src/osm/applications/utils/change_tags/change_tags.py --dry-run
--verbose --check-api --file Iceland.osm  --module iceland --function
test
Nodes: 259621/0, Ways: 5288/0, Relations: 0/0, 0 complete
Read relation

API + Licensing Update

SteveC has posted 2 import updates rolled into 1.
http://www.opengeodata.org/?p=459

Shaun McDonald has also just announced the launch of "Crap-O-Surface 
Detector" with OSM smoothness tag support.

Any other important April 1st announcements I miss?

Thanks Shaun/Matt, I didn't get to try it out today but will do so as 
soon as I can.

Wasn't Android Java-only or is there support for applications in C?

What was your motivation to use your own binary format?

Did you look at OsmBin?
What was the shortcommint in Navit's format?

Can you elaborate on this some more?
What ideas do you want to combine?
