Create a raster layer from a raster image 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
- Create an
ImageServiceRaster
using the service's URL. - Create a
RasterLayer
from the image service raster. - Add the raster layer the the map.
Relevant API
- ImageServiceRaster
- RasterLayer
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.
