Hi all, Today I have (finally) worked on large features in Canvec data (forests, water, etc.), and I have come up with a method how to deal with them. This currently involves PostGIS, but maybe I'll use GEOS or another method, so that it isn't necessary to load data in a DB. More details will follow soon, since I need to clean up code / sort out things a bit, and eventually integrate it into the canvec_to_osm.py script.
Right now I've uploaded (only) wooded areas in the Charlevoix region in Quebec. This already makes the map look entirely different! The result can be found here [1]. Changesets: [2] and [3]. You'll see faint horizontal and vertical lines crisscrossing the area. This is an artifact of making the features smaller (0.1 x 0.05 degrees). This will be dealt with with the "gamma" option which is part of the new Mapnik 0.7.0 release. This will probably be used in a couple of weeks on osm.org. See [4] for more info.
