Get started with the Raster Analysis service

The Raster Analysis service contains a number of tasks that allow you to perform common raster-based spatial analyses on your data.

These tasks are also available as tools in the portal Map Viewer. These tools allow portal members to perform raster analysis against layers they have access to. To learn more about accessing these tasks using Map Viewer, see Perform raster analysis in the Portal for ArcGIS Help. In some cases, the Raster Analysis REST API has functionality that is not exposed in the portal Map Viewer.

To access the Raster Analysis service using JavaScript, see the JavaScript API topic Working with Analysis Widgets.


The administrator of your organization needs to configure Portal for ArcGIS so that the Raster Analysis server capability is enabled. To use the analysis tasks, the administrator needs to grant you privileges to Create, update, and delete content and Publish hosted features. To use Raster Analysis tasks, you also need Publisher privileges.

Common patterns

The tasks in the Raster Analysis service all share a common pattern described as follows:

  • For most tasks, one or more of the input parameters are rasters. These rasters can come from an image service, map service, or in the form of a raster dataset. See Raster Input for more information.
  • As described in Raster Output, all raster analysis tasks create new data. How data is returned to you is controlled by the outputName parameter.
  • All tasks have a context parameter, which controls certain aspects of task execution. The context parameter has two properties, Extent and Spatial Reference.
  • All tasks execute asynchronously. That is, when you submit a request, a job identifier is returned to you, which you can use to track progress and retrieve results. See Checking job status for more information.
