Hi Even,
I need to reinstall my OSM database due to the license change to ODBL.
Usually I use osm2pgsql for that, but I am willing to sacrifice a little
downtime of my DB in order to test the GDAL implementation. Before
storming ahead I wanted to know how far you are with the driver
implementation - is there anything I need to be aware of? Are you
interested at all in a benchmark comparison between GDAL and osm2pgsql?
I'll be using the planet file, so thinks will take a while ...

Hi,
Following the recent brainstorming with Jukka, I've pushed into trunk a driver
to read OpenStreetMap .osm / .pbf files .
No particularly exotic dependencies : SQLite (and Expat for OSM XML files)
See http://www.gdal.org/ogr/drv_osm.html for the details (will be available in
a few hours).
The performance to convert
http://download.geofabrik.de/osm/europe/finland.osm.pbf into a Spatialite DB is
the following one on my PC (Core i5 @ 2.67 GHz with 64bit GDAL) :
$ time ogr2ogr finland.sqlite finland.osm.pbf -f SQLite -dsco SPATIALITE=YES -gt
10000 -progress --config OGR_SQLITE_SYNCHRONOUS OFF
real 4m31.194s
user 3m33.020s
sys 0m46.070s
Testing with larger areas, like whole France or Europe, shows sluggish
performance when ways are built from nodes, but that's perhaps expected. I
didn't compare with other tools to know if the indexing or request strategy is
particularly bad.
The data/osmconf.ini configuration file is pretty basic and its settings could
likely be improved with some tweaking. Contributions welcome.
An improved version of the driver could allow specifying custom layers,
instead of the 4 fixed ones.
Happy testing,
Even
