OpenTopoMap

OpenTopoMap (opentopomap.org) is a project aiming at rendering topographic maps from OSM and SRTM data. The map style is similar to some official German or French topographic maps, such as TK50 or TOP 25.

In January 2026 OpenTopoMap got a new server. The map data has been updated and is getting updated regulary. The server is powered by Top-O-Map (top-o-map.com)
