What I do with the statscan data is 1. Load the larger (ie province wide )shapefile into postgis with shp2psql 2. Generate a smaller shape file with something similar to the stored procedure listed ont he wiki page (http://wiki.openstreetmap.org/wiki/Geobase_NRN_-_OSM_Map_Feature#Road_Names_from_StatsCan) 3. Run RoadMatcher on the smaller GeoBase shapefile and the StatsCan shapefile 4. I then pass the road matcher result to geobase2osm with the -n option. If you need more details/help with any of these steps let me know where the gaps are and I can try to expand. > OK, so uploading the complete out.osm file is enough.

I feel the complete files are useful becaues it gives someone the geobase view of things. I find the excluded files are only useful to point out areas where geobase might have missed roads or pointing out areas that likely need some manual attention. If your giving manual attention to areas before you uplaod to OSM then having the excluded files might not be that valuable to someone else. > > Frank > > > _______________________________________________ > Talk-ca mailing list > Talk-ca@openstreetmap.org > http://lists.openstreetmap.org/listinfo/talk-ca > _______________________________________________ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
