[Talk-ca] Accuracy of CanVec vs Yahoo?

[Russell P]

Around Vancouver I have found CanVec buildings to be quite inaccurate, so i
would use Yahoo there. Best to do some mapping on the ground though with
your GPS so you can be sure that Yahoo is properly rectified because I know
quite a few areas in my neighborhood where yahoo imagery is off by like 100m
and is all warped. :(
I wish google would come on board..

When importing the data do we favour yahoo existing data in OSM (which is
obviously traced from satellite imagery)  or CanVec?   I'm assuming CanVec
for parks would be based on official park boundaries rather than yahoo, line
of site on open spaces.   So parks would be better coming from CanVec.  But
what about buildings?
