[Talk-ca] Accuracy of CanVec vs Yahoo?

[Sam Vekemans]

Hi,
There is also the Spot5 imagery :)
and the CanTopo geoTIFFs to compare.
for those parks that i origionally converted, you need to compare with
CanTopo as that is more accurate.

and as Russel and Tyler Just mentioned.  It's really a combo of both.   and
check the local GPS tracks
.... this is why local mappers are working on local tiles, where possible :)

So it isn't a rush eithor,
Cheers,
Sam
