center of the Bavarian Association for the Blind and Visually Impaired offers maps for any address in 3D.
The tactile Cards are made of sturdy, slightly flexible plastic and are created with a 3D printer. The size is 17x17 cm with a standard scale of 1: 2000. The map allows a good recognition of even dense inner-city areas. Building floor plans, streets, footpaths, sidewalks and railway lines are easy to differentiate. Rivers and lakes can also be recognized by their surface structure. The desired address is marked with a small point. 340 by 340 meters are shown.
The current map material from OpenStreetMap is used for the models. An application converts the essential elements into a three-dimensional representation.
