Talk:CanVec
this is archived notes
Needs to be developed further, list of items User:Fsteggink is working on
- canvec-to-osm Python script (will be available directly from NRCan ftp server as .osm files)
- tool to split large features in shapefile, see [1]
- tool to merge multiple OSM files TODO
- tool to deduplicate nodes in progress (JOSM is too slow)
- part of water bodies need to be converted to coastlines manually
- Tool to split large OSM files into managable 'chunks' (or working units) Further than the NTS Grid 999xx99 into 25 smaller areas (coded "a" to "y"). (use OSM splitter)

Status [old]
Import Progress
old As of a week ago, the canvec data is available to use, however, the script is still at BETA 0.49 so its gonna still change :) But my manually going through it, its easy to fix up errors.
See CanVec Import Status for the progress chart.
Import Script
old See page canvec2osm for the current version (which is still in BETA phase) please comment on the talk-ca list, as questions will be answered much faster that way.
Bug Reports
old Please see canvec2osm and list errors you find as another bug# or discuss on the talk page rather than using the talk-ca list (as it's likely to get lost in the archives quickly) :)

Map Features
CanVec - Feature Catalogue, Edition 1.0.2 (PDF version, 1,123 KB) This document describes all of the CanVec's features and their attributes. More ifnormation can be found at the [Canvec/OSM Map Features|OSM Map Features] page.
Garmin IMG tiles
I have converted 4 of the 6 sample canvec.osm.zip files into a routable Garmin IMG tile.

too much wood?
The natural=wood areas in Canada look weird. Take for example this map. The first thing that strikes me is that there are *squares* of forest, which is obviously an abberation. The second thing of course is that some forest is missing. I would be quite surprised if the forest stops abrubtly like that north of Ottawa. The third thing is that there are lines crossing the forest which also seem to be an abberation. I assume that is related to the way the data is formatted, but it should be fixed.
Lastly and more importantly: the data makes national parks and such important features mostly impossible to distinguish (if they exist at all). The comparison with US data (vermont, in this case) is striking.
Oh and another thing, not sure it's related: there's this weird triangle here, and only at that zoom level... -- TheAnarcat 22:42, 4 January 2012 (UTC)
