Topographical Map Server

Canada now has put its entire topographic map database online. The map server, Toprama, does two things better than Google maps. You can get the contour elevation and spot elevation. And the best feature is that you can distances that don't depend on driving directions. Not that driving directions are not useful but if want to find out the width of a bay you want the distance from two points not the drivable distance betweeen them.

The limitation is that the source for the Top maps can be out of date. Google depends on satellite information that is relatively un processed. The map above has the elevation in feet. I was looking at Toronto and the Greenwood Racetrack was still showing.
