I just finished converting the Surrey road data to a .osm file. This may be of interest to anyone mapping in the Surrey area.
I've posted it to http://maps.paulnorman.ca/surrey/SurreyRoads2010.zip along with the ogr2osm translation file I wrote. I'm not planning to import it wholesale, just selectively if I have to update a road, and I plan to move some tags over on major roads (maxspeed, lanes, hgv=*, hazmat=*) Some notes on the strengths and weakness of the data Weaknesses: - Ways are not dualized. This road data was intended for their printed maps which do not have dualized roads. Incidentally, I purchased one of those maps. - Some roads are off in position. Most are extremely good with <40cm error, but some have jogs that are out of place by a few meters. - Odd classifications. Some roads are classified strangely. This only impacts secondary and primary roads. Strengths: - It is very recent, with roads not constructed until late 2010 present in the data - The postions seem slightly better than GeoBase - It has truck access and hazardous material restrictions - It has speed and lane information The tagging of a typical road is highway=residential lanes=2 maxspeed=50 name=58 Avenue source=City of Surrey 2010 GIS Data surface=Asphalt surrey:geodb_oid:496 while a highway looks like hazmat=designated hgv=designated highway=primary etc. _______________________________________________ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
