[gdal-dev] New OGR driver to read OpenStreetMap .osm / .pbf files

[Frank Broniewski]

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 ...
