World Shaded Relief

Map Service Name: World_Shaded_Relief

Description: This map portrays surface elevation as shaded relief. This map is used as a basemap layer to add shaded relief to other GIS maps. It is especially useful in maps that do not contain orthoimagery. The map resolution (cell size) is as follows:

30 Meters for the U.S.
90 Meters for all land areas between 60° north and 56° south latitude.
1 KM resolution above 60° north and 56° south.

The shaded relief imagery was developed by Esri using GTOPO30, Shuttle Radar Topography Mission (SRTM), and National Elevation Data (NED) data from the USGS.
