Map Service Relay
The "Map Service Relay" layer type displays web services (OGC WMTS) from an external server in a PlexMap Viewer (e.g. PlexMap 2D or PlexMap 3D) without storing or caching the service or data of the service in PlexMap (services "looping through").
This can result in improved performance if the external server provides good performance, as external layers always offload the deployed PlexMap server.
