[Talk-ca] Geobase import by provinces

[michcasa at gmail.com]

May be I was not clear. I agree with you, user effort is very important and  
we should keep existing OSM data. However Geobase data will provide a very  
very very good coverage and accuracy where no OSM data is available. The  
use of Geobase data will allow the users to work locally to improve the  
initial import and capture other features. For example, I import Geobase  
data in Kamploops area  
(http://www.openstreetmap.org/?lat=50.687&lon=-120.355&zoom=13) where I  
kept the existing OSM data. You will see that Geobase help to cover the  
area.
