This page describes the World Elevation Service, configured as a Project Source, used for initializing Digital Terrain Model; the terrain height without for example buildings, trees and other objects.

The service of this project source is provided by ESRI and its coverage is Worldwide. This service is a combination of individual services per country or region, as listed in the tables below. The service always returns the best possible accuracy it has, based on the coverage within a country.

The coverage with accompanying accuracy can also be inspected with this ArcGIS Viewer[1].

More background information on the service can be found here[2].
