[Talk-ca] Canvec vs. GPS

Hey everyone

I am presently preparing a careful import of Canvec data into Mantario 
area. I have stumbled across a trail that appears to be a GPS track. The 
problem is that while this trail did not overlap with the old old low 
detail lake data, it conflicts in some areas with the Canvec data. Which 
data should I adjust? The overlap between the two ranges for 17cm to 
30m.  An inspection using Landsat (sadly the best imagery for the 
region) favours Canvec. I realize that this is a tricky subject. I'm 
assuming Godwin's law does not apply to this list.
