DEM

This digital elevation model, or DEM, of the Dundas Valley, in Hamilton, Ontario, CA has been colorized to bring out the relief. The lower elevation values are shaded in green while the higher ones are orange. It looks like they have overlaid the DEM with a layer of street data for reference. If this map is used for public display, the street data would certainly help give people a better understanding of location. By rotating this DEM you might get a better view of the elevations and really see the differences across the subject area. This site has some fantastic images and maps.
