If you live outside the western countries that already offer topographic map services TrailRunner can use, you might want to take a look at the topographic map collection of Perry-Castañeda Library of the University of Texas at Austin. They provide tons of topographic maps created by the US Army. The map above depicts the Ivory Coast in West Africa, a place I've been to years ago.

It would be great if someone could tile these into a common web service format. But until that is done, you can manually add the maps to TrailRunner and calibrate them.
