[GRASS-user] Re: osm import

[Casey Vandenberg]

There are scripts that exist for converting osm to gml. Then they can be 
imported directly using ogr.

I did not have much luck with using XSLT with the the xml styles 
location on the Open Street Map wiki 
(http://wiki.openstreetmap.org/wiki/Converting_OSM_to_GML), but the 
python script (http://www.chzsoft.de/geo/osm2gml.py.txt) worked well for me.
