The free OpenStreetMap WMS from terrestris is available to everyone and can be easily integrated wherever the WMS standard is supported. The flexible access enables scales from 1:1,000,000 to 1:25,000 worldwide. For more detailed representations up to a scale of 1:1,000, the premium version is available.
Free WMS service with worldwide coverage in color or grayscale
The OSM WMS service offers maximum flexibility and unlimited access. Free data sources such as OpenStreetMap, Natural Earth and GEBCO are combined in a clean map design, available in color and grayscale.
In addition to the classic topographic map display, the access also includes additional layers – including a label-free topographic map and a digital terrain model based on SRTM30.
Thanks to scale-dependent display, the appropriate details are visible depending on the zoom level. Free access is possible up to a scale of approx. 1:25,000; beyond that, a watermark appears. For use in larger scales, our OWS Premium Service can be used. This offers greater stability and better performance, as the circle of users is limited and a more powerful server is used.
The service is provided via a GeoServer and accelerated with the help of MapProxy. And thanks to regular updates and powerful servers, the service runs reliably and can be seamlessly integrated into almost any GIS system.

Overview
Easy integration through interfaces
Access to the service via OGC-compliant WMS interface.
Worldwide coverage
Maps down to building and house number level.
Caching
Pre-cached server-side in all OpenStreetMap zoom levels and additionally in the scales 1:1,000,000, 1:500,000, 1:250,000, 1:100,000, 1:50,000 and 1:25,000. Afterwards dynamic on-demand caching for continuous access and excellent performance.
Scalability
Tile sizes up to 2048 × 2048 pixels. Recommendation call in 256×256 pixel tiles.
Server location
All servers used are located within the European Union (Germany and Finland).
Performance-optimized header
Map tiles delivered by the services signal to clients via HTTP headers that the tiles may be cached client-side. This improves performance because requests do not have to be made again.
Limitation
Unlimited map retrieval without quantity restrictions.
HTTPS encryption
Secure provision of services via HTTPS.
Data sources and design
Use of free data sources such as OpenStreetMap, Natural Earth and GEBCO Bathymetric Compilation Group, supplemented by harmonious, own cartographic styles in color and grayscale.
Sustainability
100% green electricity for servers and company location.
Map formats
Map requests can be made in PNG and JPG format.
Coordinate systems
Support of common coordinate systems such as:
- EPSG 4326 (WGS84)
- EPSG 25832 (ETRS89 / UTM zone 32N)
- EPSG 25833 (ETRS89 / UTM zone 33N)
- EPSG 31466 (DHDN / Gauss-Krüger Zone 2)
- EPSG 31467 (DHDN / Gauss-Krüger Zone 3)
- EPSG 31468 (DHDN / Gauss-Krüger Zone 4)
