Toronto Transit Map
Torontoist calls this transit map of Toronto “the best map ever in the history of anything.” What it looks like to me is the TTC transit map superimposed on a Google Maps interface. Not that that isn’t impressive in and of itself, but the streets, etc. are part of the TTC layer, rather than Google Maps itself. In other words, other than the stations, this appears to be a single image, rather than a bunch of polylines. Problematic from a usability standpoint (particularly at the edges), though it explains how the transit lines and symbols could be orthorectified so cleanly. Via All Points Blog.
