[Talk-ca] Nunavut has a very pour data coverage. Why not Integrate BNDT/CanVec dataset from Department of Natural Resources Canada?

Oh thanks for the explanation. I just add some trails, gas stations and change some roads etc. so I didn't had an idea how much work it is. Great that you do the work! I am very happy about it.

Ivo:
	A couple of reasons that it takes me soooo long, is:

	A lot of the time at, least down south is that there is existing data already mapped. I'll open a canvec tile and then download the existing data. Now for example say some one has mapped a railway line I have to remove the rail way line from the canvec data set and then make sure the segments are connected. The I'll run Josm validator and remove all the duplicate nodes. Then I'll review the combined data and connect lakes and rivers so they are "one body" of water. Since canvec chops lakes and rivers in little pieces. Now granted I don't do this with the forest data, had to decide what was a reasonable time / effort to make the data look "pretty". Then upload the data.

	So basically it all takes time and it is a hobby so I do a little now a little later and well you get the idea.

	If I do 4 tile segments a day which I'm guessing is an hours work

Tile 120 has
Blocks B, C,  D, E, F, G
B has 03, 04, 05, 06, 11 12, 13, 14, 15
I'm looking at 15 tile pieces for 120B would take say 4 days to import.
Then onto the 120C, with a quick look at 120 C I would guess a week or 2

So If, I just blindly imported data I could fly through the tiles and end up with a pile of spaghetti.
