Add an ArcGIS Map Image Layer from a URL to a map.

screenshot

Use case

ArcGISMapImageLayer instances are rendered server side as a single raster image, so they always show the latest data at the time of the request. Since the data is rendered as a single image, it can have performance benefits versus a feature layer with complex geometries.

How it works

  1. Create a new Map and set it to a MapView.
  2. Create a new ArcGISMapImageLayer with an input URL.
  3. Add the layer to the map.

Relevant API

  • Map
  • ArcGISMapImageLayer
  • MapView
