Add an ArcGIS Map Image Layer from a URL to a map.
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
- Create a new
Map
and set it to aMapView
. - Create a new
ArcGISMapImageLayer
with an input URL. - Add the layer to the map.
Relevant API
- Map
- ArcGISMapImageLayer
- MapView
