Topographische Karten aus OpenStreetMap
OpenTopoMap ist eine freie, topografische Karte, die aus den Daten der OpenStreetMap und SRTM-Höhendaten generiert wird. Der Kartenstil orientiert sich an den amtlichen Karten und setzt auf gute Lesbarkeit durch hohen Kontrast und ausgewogene Signaturen.

History
OpenTopoMap was founded in 2011 by Stefan and Philipp as an experiment. The goal was to imitate the official topographic map style of German Vermessungsämter with free software and OpenStreetMap data. At that time, the "slippy map" on openstreetmap.org looked kind of childish and it was always emphasized that OpenStreetMap was a database, not a map. I spent an incredible amount of time into optimizing the map style level by level, starting each level again on a white plain and experimentally adding map features by their tagging and manually tweaking each color, line width, casing width, pattern, symbol etc. until I was satisfied. While studying at University and still without family obligations, time was available. At that time, the University of Erlangen thankfully supported us by financing a local server. The number of users increased month after month. Currently, OpenTopoMap has more than 2 million distinct users per month and is highly ranked and well-known. It was never my goal to make any profit, at the cost that I never gave any service or support guarantee. After being employed as research assistants for many years (not in cartography or similar...), the connection to the University faded away and we now need to retire and return the machine.
Renderer shutdown date
The main server will be shut down on 18.12.2025. It contained the massive postgresql database and the Mapnik renderer. The previously rendered tiles between zoom level 0 and 13 are backed up to an external, smaller server, which will continue to serve those pre-rendered tiles. Please be prepared to lose zoom levels 14+!
