[Talk-ca] Canadian imports: good or bad?

[Andrew Allison]

Hello:
	I would take from this discussion that canvec data needs to be imported
into the white spaces of Canada.

	I may be missing some historical experience / discussion of this
process.

	Part of the fun aspect of OSM is finding things wrong on the map and
correcting it. I think this is how people get hooked on OSM. Letting
"errors" creep in may in fact help to get more people interested in OSM.

	Some guide lines should be developed to give mappers direction on how
to import canvec.

	When a mapper undertakes to import a canvec "square" due care be taken
to verify as much as possible using imagery overlay. I realize with some
imagery your going to be awful lucky if you can even spot a road or
river down there :-)

	When importing canvec the mapper / importer should treat the area they
are importing as they would their own neighbourhood.

	If the area importing contain a large body of water convert it to
natural= coastline. Run validator against each tile to minimize crossing
ways and such. When streams cross a road assume that a culvert exists
and the stream go under the road. Judgment would have to be used
depending on the some urban, remoteness, primary road vs hiking trail
aspect. I'm at a loss what should be done with those big square
polygons? Joining / removing ways that are spit due to the tile nature
of the canvec data.

	Now if someone would move that darn cloud in Sydney so I could tell if
the train tracks go under the road :-)

	Comments, I think I should probably crawl under a rock I may have
stirred a hornets nest. I'm going to go out geocaching, judging by the
number of caches in an area there must be a trail there that not on the
map yet.

	Andrew
