freemapper2. What you need
- A computer with Windows, macOS or Linux. No GIS or other programs are needed.
- OpenOrienteering Mapper (free) or OCAD 12 or newer.
- An internet connection for the first download.
- Free disk space:
- The first time, freemapper downloads the OSM extract of the state: about 300 MB for Brandenburg and Berlin, about 270 MB for Saxony, about 180 MB for Saxony-Anhalt, about 55 MB for Hamburg, about 350 MB for Hesse, about 160 MB for Schleswig-Holstein (without Hamburg), about 130 MB for Mecklenburg-Vorpommern, about 510 MB for Lower Saxony (with Bremen), about 275 MB for Rhineland-Palatinate, about 55 MB for Saarland, about 20 MB for Bremen. In North Rhine-Westphalia and Baden-Württemberg these are the extracts of the Regierungsbezirke, 130 to 225 MB each, two of them for an area on a district border. The extract is reused by all projects.
- On top of that, each map usually needs 10–100 MB.
- Before each download freemapper checks the free space of the cache and the project folder. When they are on different drives, it checks each one. It keeps 1 GB free on every drive. If not everything fits, freemapper leaves out the surface model (the nDSM template) and, when an older OSM extract is cached, the update of that extract. It warns for each part it leaves out. Every map needs the map data, the terrain model and the orthophoto. If those do not fit, freemapper stops before it downloads anything.
- An area in Brandenburg, Berlin, Saxony, Saxony-Anhalt, Hamburg, Hesse, Schleswig-Holstein, Mecklenburg-Vorpommern, North Rhine-Westphalia, Lower Saxony, Rhineland-Palatinate, Saarland, Baden-Württemberg, Bremen or Bavaria. Thuringia is still missing.
- Optionally an AI assistant such as Claude, so you do not have to type commands.
