[Talk-ca] Importing CanVec – Worth it?

[Nate Wessel]

John, that's bad advice. An import that introduces new errors is not a 
good import. I do hope we can all agree on that. It's an importer's job 
to resolve errors, not to leave a mess for others to clean up.

...

I was meaning to reply to this anyway. I would tend to be on the side of 
not importing CanVec data; the gaps are ugly, yes, but maybe those 
imports never should have been done in the first place; I don't have a 
strong position on that. Regardless, as these areas aren't really 
getting filled in by many actual editors, it seems quite likely that the 
imported data will just continue to grow stale over the years. Better to 
know what we don't know than to think we know what we don't.

Also, if anyone wants to make a map with a bunch of natural landcover 
data, they're probably better off using raster sources than vector data, 
especially outside of urban areas. IMO, OSM was never going to be well 
suited to Canada's north. That's raster data territory and OSM has a 
vector data model.

That said, I have actually been editing a bit up north lately, and 
making some actual progress adding rivers and lakes and whatnot - I'd 
definitely welcome some manual help!
