Service definition by the Open Geospatial Consortium that defines exchange of bitmap tiles for map display
Goal is to unify the exchange of bitmap tiles for web-mapping.
The Service has the following operations (for full details check the specification)
- GetCapabilities (Advertises supported layers, projections, grids, formats, etc)
- GetTile (Returns the requested tile)
- GetFeatureInfo (provides details about a selected feature)
- GetLegendGraphic (renders a map legend)
There are a couple of competing alternatives for this standard; TMS and WMS-c. MapCache and GeoServer support all of these protocols. Mapnik is a typical tool that supports these only. Some new vector protocols introduced the tiling concept for Vector Data.
