SOSM provides a number of services for the Swiss OpenStreetMap community. These range from contributor support by making aerial imagery and other data sources available, to end-user services to make low volume, incidental use of OpenStreetMap data easier.
Most of these services are available via the osm.ch domain which is owned and operated by SOSM.
SOSM runs an instance of MapProxy to provide imagery to Potlatch 2 and iD editor users and additional imagery not available online.
Currently it provides tiled access to imagery from the cantons Aargau and Solothurn and the cities of Berne, Geneva and Zürich and some further special purpose layers.
Most of this imagery is included in the default configuration of the editors iD, JOSM, Potlatch 2 and vespucci and does not need to be configured manually.
Map Tile Services
SOSM provides a map tile service with multiple different styles and projections. A list of available stzles is available here.
Overpass Service for Switzerland
SOSM provides both an instance of the overpass API with Swiss data and a matching overpass turbo user interface. This is particularly useful together with uMap.
Taginfo provides statistics and information on tags used in OpenStreetMap taginfo.osm.ch provides this just for Switzerland.
One of the most frequently asked question is “how can I show my POI/data/route on an OSM based map?”. uMap provides a hosted solution that provides that and more. If you have an OSM account you can immediately start using it at http://umap.osm.ch/ .
OSM Data for Switzerland
On http://planet.osm.ch/ SOSM offers daily updated extracts of OSM data for Switzerland, hourly “diffs” that you can utilize to keep a database with OSM data up to date and a daily updated map file for the OSMAnd app.
http://routing.osm.ch/ provides up to date routing for Switzerland for cars, bicycles and pedestrians.
