About CAD Mapper

CAD Mapper generates CAD files for a selected location using public map data from sources such as OpenStreetMap, NASA, and USGS. Users define an area with the online tool, edit the layered drawing in CAD software, and render it in their design program. The homepage lists AutoCAD, SketchUp 8+, Rhinoceros 5+, and Adobe Illustrator as compatible programs.

Free use is limited by area size. Files for areas up to 1 km² are free and include all available data, but require sign-up to download. Areas up to 100 km² are available for a small fee, with a discount for registration using an academic email address. Free whole-city road network files for over 200 metro areas can be downloaded without an account. These are simplified two-dimensional DXF files. Building height and topography data are available in many locations, not all.
