Details

• "wfs" : Web Feature Service designed to return data in vector format (line, point, polygon, ...) ;

• "wms-r" : Web Map Service focuses on raster data ;

• "wmts" : Web Map Tile Service is similar to WMS, but instead of serving maps as single images, WMTS serves maps by dividing the map into a pyramid of tiles at multiple scales.
