Catymag, back on highly detailed road network. Have you often seen such a highly detailed network (or even more detailed) on other maps? It seems like an excellent idea to build very highly detailed road networks for logistics, taxi, etc. I large cities taxi drivers are often told to pick up passenger at one of many numbered entrances (porches) into large building. Routing to particular porch number would be attractive for some drivers. By chance, have you seen such very detailed maps?
