OGC Help for ArcGIS Online
ArcGIS Online currently supports two OGC specifications: Web Map Service (WMS) and Web Map Tile Service (WMTS).
- OGC Web Map Service (WMS)is a dynamic map service that follows the specifications of OGC. You can add OGC WMS layers to maps you create with the ArcGIS.com map viewer. You can also add OGC WMS maps as items in ArcGIS Online.
- OGC Web Tile Map Service (WMTS)is a set of cached image tiles that follows the specifications of OGC. You can add OGC WMTS layers to maps you create with the ArcGIS.com map viewer. At this time, you cannot add OGC WMTS maps as an item in ArcGIS Online.
