That does look like a good candidate. A quick check at the website reveals a huge list of vector and bitmapped map formats that it can read. Do you know anything about the kinds of data that can be obtained from libgdal? Full-color map images would be fairly useless to us (except as a background for a plot). We could do some interesting things with gray-scale image data via plimage; 3D topographic data via plcont or plshades; and outline map data via a changed API for plmap.
