Set map spatial reference

Specify a map's spatial reference.

screenshot

Use case

Choosing the correct spatial reference is important for ensuring accurate projection of data points to a map.

How it works

  1. Instantiate an Map object using a spatial reference e.g. ArcGISMap(SpatialReference.Create(54024)).
  2. Instantiate a Basemap object using an ArcGISMapImageLayer object.
  3. Set the base map to the map.
  4. Display the map in a map view.

Relevant API

  • Map
  • ArcGISMapImageLayer
  • Basemap
  • MapView
  • SpatialReference

Additional information

Operational layers will automatically project to this spatial reference when possible.
