I am making a historical atlas on Wikipedia, and i used to have a map generator to create base maps, but this map generator is now gone. I have tried arcgis webmap, but couldn't find a map with rivers and without modern roads and political boundaries. Is it possible for me to create base maps here, with rivers, mountains and coast lines? Here is the link to my atlas: http://en.wikipedia.org/wiki/User:Daanschr/_Historical_maps
Most of our base maps contain "modern" information in them. We do have a shaded relief base map, with no labels or roads, but there are no rivers in it.
