Anybody know a source (preferably online) for viewing/creating topographical maps with only the terrain features and elevation lines, no roads or towns?
I was inspired by this article on creating your own maps w Google Maps, but I'd like to be able to use this for colony worlds and the like, copying useful bits of real geography and then adding spaceport, housing, etc as appropriate for the colony.
I've used a variety of map and satellite photo sites in the past for useful overviews of our farm, but none seem to have the ability to remove the overlay of roads, etc - a pity, since in some of these, such as the Map view with Terrain in Google Maps, you are clearly seeing photos with a layer overlaid to mark the roads and towns.
