Esri continues support for Open Geospatial Consortium (OGC) services by upholding standards and working toward increased interoperability. Now, the map viewer in ArcGIS Online contains additional options for appending custom parameters to:
- OGC Web Map Service (WMS) layers
- OGC Web Map Tile Services (WMTS)
- OGC Web Feature Service (WFS) requests
Also, when you add WMS data to a map using the map viewer you can choose which layers to add instead of adding the entire WMS service.
