[Talk-ca] canvec data offset

[Bégin, Daniel]

Bonjour,

I'll have a look to see if I can do something for it in the next release. 

I suspect that might be caused by data resolution. Lat and Lon are stored in decimal degrees with 7 digits precision (48.1234567). The 7th digit will provide a precision around 0.001 meter. The 6th digit a precision around 0.027 meter witch look like your 0.03 meter.

Cheers
Daniel

Subject: [Talk-ca] canvec data offset

ive been working with canvec for a few days now, and ive noticed some of the data is offset by 0.03 meters its not matching up with nearby tiles

for example 021O10 doesnt match up with 021O07

ive noticed the problem on other tiles aswell, but didnt think to write them down
