Topo-map of Portland and Astoria

Very nice and detailed topographic map of the areas around Portland and Astoria (Oregon). The maps include detialed contour lines as well as roads (with roadnames!). The map can be either downloaded as an .exe file or as a .zip file. The .exe includes the map automatically in Mapsource, the .zip files includes all necessary files to do the same manually, or to just send the map directly to your GPS device.
