[Talk-ca] Fwd: GeoBase vs CanVec

Sat Aug 21 01:29:38 BST 2010

From an observer perspective.  In the areas I've entered CanVec v6 seems the next version of GeoBase.    A lot of roads are the similar but CanVect has a lot more detailed points than the currently imported GeoBase.   Ie geobase import has a winding roads as a set of inverted triangles were CanVec has rounded edges.

But that's just the areas I've done

As for the official difference, I'll wait too for that response.
