View and qualify the data evolution in OpenStreetMap over the last month.


CH-OSM is a GeoDataSolutions project, which offers services related to thematic data from OpenStreetMap. Currently these services are provided at the scale of Switzerland and Grand Genève metropolitan area. The data of the different services are updated daily.

Geodatasolutions is a company that aims to integrate, produce and implement geodata and mapping systems for public and private companies. Valuing open source data is also in our sights for a more transparent world and less dependent on some big corporations technology.

OpenStreetMap is a mapping project that aims to build a free geographic database of the world. The project is often referred to as the ‘Wikipedia of cartography’. Anyone can participate in improving the map by adding or updating data! More information here:

The thematic data disseminated by CH-OSM are all derived from the OpenStreetMap geodatabase.
