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.

In a recent post [1], you said that to import OSM maps, one
can use v.in.ogr, but I don't see a driver for OSM maps in
ogr. Could you explain ?
      

umm, probably just a dream, it was a former Summer of Code wish
for GDAL which apparently never happened.
    
Yes, I saw that, too. Nice dream, though :wink:

a web search finds these which may help:
   http://www.google.co.nz/search?q=osm2shp (.shp will be lossy!)
    
apparently .NET-based, don't know if it works with Mono.
But obviously the easiest is just to use the CloudMade shapefiles: http://downloads.cloudmade.com/

   http://svn.openstreetmap.org/applications/utils/import/ogr2osm/ogr2osm.py
    
That works the other way around, i.e. ogr -> osm, or ?

and a crappy old osm2grass script I wrote circa GRASS 6.1:
   http://sites.google.com/site/hamishbowman/gpsdrivefiles#osm

but probably your best bet is to try the v.in.gpsbabel module
with a recent version of GpsBabel. ([to be] renamed/rewritten as
v.in.gps in GRASS 7)
    
Sounds like an interesting solution. Limited to lines and points, though, or ? For the record, that's gpsbabel 1.3.5+

and probably the best near-term strategy is to help verify that
GpsBabel's import filter does not lose any data in the OSM tag
-> GPX attribute conversion.
    
I'll ask my colleagues who might use this to check.

then either v.in.ogr + OGR's GPX driver or v.in.gpsbabel's GPX.
    
Why not directly v.in.gpsbabel on the osm file ?

finally "osm2pgsql"
    
for the record: http://wiki.openstreetmap.org/wiki/Osm2pgsql

and then connect GRASS to the PostGIS database
might be the most robust approach. I don't know much about
PostGIS -> GRASS but it is something I'd like to read about on
a GRASS wiki page :slight_smile:
    
Well, it should be a simple v.in.ogr. There is an example on the v.in.ogr man page.

Thanks for the exhaustive response !
