[Talk-ca] Off-topic: general Canvec issues

[Bégin, Daniel]

Bonjour Brent,
 
I'm forwarding your email to the manager in charge of the Canvec product. There are many project teams working on rethinking Canadian mapping nowadays. May it is just the good timing to have your requests consider!
 
Regards,
Daniel

Daniel,

  While this is not directly related to OpenStreetMap, I'm posting this here since the OSM community seems to be the most active set of public users of Canvec data.  The goal of this post is to improve Canvec (and therefore hopefully improve OSM).

  As a method of testing the latest release of Mapserver (http://mapserver.org/), I attempted to use Canvec v7 to render a CanTopo <http://geogratis.cgdi.gc.ca/geogratis/en/product/search.do?id=A6291EF5-F3FC-A29F-3162-DE4DB194FD38>  style map.  See my mapserver post <http://lists.osgeo.org/pipermail/mapserver-users/2011-May/068731.html>  for more details on my efforts.  While the issues I covered on the Mapserver email list are specific to Mapserver rendering shortcomings, there were a few other issues related to the Canvec data.

  One of the main issues I ran into was the Toponymy (TO) layer <http://wiki.openstreetmap.org/wiki/CanVec:_Toponymy_%28TO%29>   is represented by point geometry preventing me from rendering the mountain range text (for example) in a curved manner as done in CanTopo.  Is there any possibility of having NRCan change the geometry to LINESTRING?  Or perhaps having a _TO_1580009_1 (linestring) shapefile for those names representing linear features  in addition to the existing _TO_1580009_0 (point) shapefile?

  Some of the other less serious issues (these can be handled by pre-processing the Canvec data):

Contour layer (FO_1030009_1):  no attribute for major/minor contours preventing bolding of major contours
Stream Layer (HD_1470009_1): major streams broken at tributary intersections preventing single label for streams

Thanks!
