Elevation analysis service

The elevation analysis service performs analyses on the elevation in Terrain data from the ArcGIS Living Atlas of the World in order to derive surface information, such as calculating visible areas, returning profile features, and summarizing elevation values for the input feature data. The elevation data used by these analyses is available at different spatial extents and resolutions. See the data coverage section for more information.

Key features

  • Create viewsheds to identify visible areas based on input observer locations
  • Find elevation values along input lines and return a profile feature
  • Calculate summary statistics for elevation values in areas covered by the input features

Access the services

To access the spatial analysis service, you need the following:
