Haaa! It makes sense... Originally, hydrography and vegetation were fitting together. Now that we are gradually replacing the older hydrography with newer data from provinces, we find vegetation in water. It will be corrected when we will replace the vegetation with a new one extracted from satellite images 5 years ago.
The same thing can happen between hydrography and road network.

CanVec sometimes contradicts itself, for example it has trees in the water frequently. The coastline example I sent to you earlier would also be another example of where the data doesn't make sense. There are a few others that I've encountered. Typically what happens is one data source is significantly older than the other so CanVec says the land is being used for two contradictory uses at the same time. _______________________________________________ Talk-ca mailing list Talk-ca@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ca
