About OSMaxx

OSMaxx (short for "OpenStreetMap Arbitrary Excerpt Export") cuts out OpenStreetMap (OSM) data, processes it to geospatial data structures, converts it to typical GIS file formats and offers those for download.

A product fact sheet (in German) is available.

All our code is open-source and contributions are welcome.


You can find the online documentation of the schema on GitHub: Export Schema Documentation.

Useful links

These can be found in our separate downloads page.

Data sources

All data used by OSMaxx comes directly or indirectly from OpenStreetMap:

The bulk of our input data (everything not listed separately below) is verbatim OpenStreetMap data, taken from our own regularly (about every two hours, depending on the current load) synchronized database import of the OpenStreetMap planet.

Additional data sources

  • Coastlines, Water-polygons and Landmasses: These are from OSM derived data provided by openstreetmapdata.com.
  • Country boundaries: We are using the country boundaries that are based on OSM-Data, cleaned and maintained by Wambachers-OSM.website.
