Hi,

I trying to find out a way to deal with osm files using ogr.
Am I right that there is no direct support?
What format would you like to convert OSM into?
There are ready converted shape files out in the web to download
but there is only one describing attribute set. So this is also
not really usable :-(
Can you say again what exactly is unsuitable about the existing shape files?
The problem with conversion from OSM into many other formats, including
shape files, is that OSM supports unlimited attributes and the
destination file will often only support a pre-defined number of
attributes so you have to write some rules. osm2pgsql contains such
rules but you might want to adapt them; pre-made shapefiles are using
such rules as well. There is no "standard" way to convert an OSM file
into a shapefile.
Last try was using the osm2shp utility found at osm svn. But the
tool creates files larger than 2GB and stops working.
There is also a shapefile creator named osmexport at rubyforge, and
vizure.net claims to generate shape files on the fly. But in all cases
(even if you go the osm2pgsql route) you will have to select layers or
regions otherwise you'll get more data than a shape file can handle.
You can use the Osmosis tool to cut an area from an OSM file.
Bye
Frederik
