FYI, I'm just forwarding these comments over to the Canadian talk-ca list, as the national data is created in the exact same way.
And BTW, the fact that the canvec data is available in full province/national sized shape files, as a layer for each feature (should) be great news for some. This is why im trying to convert the .gml file to .shp files to .osm files to .img files (using the data as a tool for mapping perfection) cheers, Sam On 1/15/11, dinarrow <dinear...@gmail.com> wrote: > > On Jan 16, 9:45 am, Hamish <hamish.bow...@gmail.com> wrote: > >> >> regards, >> Hamish > > No criticism of your efforts at all Hamish.
