This sample shows how to add an instance of a hosted ImageryTileLayer to a
Map in a MapView.
The ImageryTileLayer in this sample shows the National Land Cover Database (NLCD) 2016 land cover types for the United States.
Tiled imagery layers can be published and hosted in ArcGIS Online. These layers are image services generated from one or more image files.
If an ImageryTileLayer is created using multiple images, the images are mosaicked together into a single image. Source images and raster files are converted
to Cloud Raster Format (CRF) when uploaded to your ArcGIS Online organization.
See the Publish hosted imagery layers document for more information
on hosting your raster data.
How it works
When the application starts, The UI allows the user to specify the land cover type to display and the
spatialReference of the view. The user can choose a spatial reference of the view from a drop down.
The view spatialReference is changed with the specified spatialReference as shown
below and layers are projected to match the spatialReference of the view:
When the user chooses a land cover type, we update the layer's renderer to display
the selected land cover type as shown below. The land cover types are displayed in a
calcite radio button group
on the right side of the application.
