The Map Layers widget allows managing the display of the Base Layer and ArcGIS, WMS and WMTS layers.

  

Referencing GIS data to the iModel essentially publishes it as raster layers in the view. Use any GIS server (ESRI, open source MapServer, GeoServer, etc.) to compose your map. Then, add new connections to the service through the Map Layers widget and access your GIS data.
