-The `atlas.layer.OgcMapLayer` class can overlay Web Mapping Services (WMS) imagery and Web Mapping Tile Services (WMTS) imagery on the map. WMS is a standard protocol developed by OGC for serving georeferenced map images over the internet. Image georeferencing is the processes of associating an image to a geographical location. WMTS is also a standard protocol developed by OGC. It's designed for serving pre-rendered and georeferenced map tiles.
