Raster layer (service)

This code sample is available for these platforms:
View Sample on GitHub

Create a raster layer from a raster image service.

Image of raster layer service

Use case

Accessing a raster image from an online service can be useful for analyzing the most up-to-date data available for an area. For example, retrieving recent results of bathymetry surveys within a shipping channel monitored for its sediment build-up would allow planners to assess dredging needs.

How to use the sample

Simply launch the sample to see a raster from an image service being used on a map.

How it works

  1. Create an ImageServiceRaster using the service's URL.
  2. Create a RasterLayer from the image service raster.
  3. Add the raster layer the the map.

About the data

This sample uses a NOAA raster image service. The service computes a hillshade image from the depth (in meters) of U.S. coastal waters.
