Hmmm. Maybe I'll hold off on importing any more Canvec roads until
Edition 8 (due in April?). Are there any other major changes in Ed. 8?
If not, I may continue to upload non-road features from Ed 7...
Best Regards,

Bonjour Brent,
For your information ...
Canvec: Next Release will include the current GeoBase road network, including
street names
GeoBase Road Network: Next release will include address ranges if completed
GeoSask Road Network: is older (2004) than Canvec (2010)
Cheers,
Daniel

Subject: [Talk-ca] Notes on a Saskatchewan import
To All,
I finally had got around to doing my first OSM data import session.
I had some spare time and was frustrated with the lack of OSM progress in Saskatchewan, so
I imported a Canvec sub tile for Melfort Sask
(http://www.openstreetmap.org/?lat=52.8086&lon=-104.6061&zoom=12&layers=O).
It was surprisingly easy, thanks to the great work of Daniel Bégin in
supplying .osm formatted Canvec data, and Steve Singer's blog on importing
Canvec
(http://scanningpages.wordpress.com/2010/08/08/openstreetmap-canvec-importing/).
I used Josm to import the geometry and Potlatch to add the street names
(the street naming was tedious, but somehow felt rewarding).
For others planning to do some OSM work in Saskatchewan, here's a summary
of free and license-friendly sources of street GIS data:
Canvec (.osm format)
ftp://ftp2.cits.rncan.gc.ca/osm/pub
- old geometry
- no street names
- no address ranges
GeoSask Road Network
ftp://portaldata:[email protected]/PackagedData/Sask_Highways/SURN09.zip
- geometry same as Canvec (old)
- complete street names, but poor capitalization and spelling:
"MACLOED AVENUE"
- no address ranges
Geobase Road Network
http://www.geobase.ca/geobase/en/search.do?produit=nrn&language=en
- new geometry
- complete street names, poor capitalization and spelling: "Macloed
Avenue"
- no address ranges
StatsCan
http://geodepot.statcan.gc.ca/2006/040120011618150421032019/1814062006_05-eng.jsp
- newer geometry but positional accuracy poor
- incomplete street names (unless you combine NAME and TYPE
attributes) "MacLeod AVE"
- has address ranges

Brent Fraser
