Very flexible and useful district maps without names or other identifying features. Not geomorphs in the sense that they don't fit together, but useful when you're building your own modern city. Also has cool Google Sketchup 3d illustrations about the effects of different types of buildings on the same street plans, thus illustrating the versatility of these maps. They work well with the Damnation City sourcebook to provide a guide to building your own city.
