WMS/WMTS Services
About
WMS (Web Map Service) or WMTS (Web Map Tile Service) is a standard protocol for serving georeferenced map images over the Internet that are generated by map servers using data from GIS databases. These maps or map data layers are mostly provided by government organizations or educational institutions.
WMS/WMTS can serve almost any type of map. Beginning with topographic maps, historic maps, satellite, and aerial images, cycling routes, town plans, ending with various data layers like cadastral maps, weather services, environmental layers, etc.More info >>.
Map services are managed in the WMS/WMTS tab of Locus map manager.
