Service Description: The grayscale shaded relief map service is a 100-meter resolution image of the United States, Puerto Rico and the U.S. Virgin Islands, created with the ArcGIS Hillshade command, with 45-degree sun elevation, 315-degree azimuth, and a z-factor of 1.0. Very dark and very light shades both represent steeper terrain. Mid-range grays represent flatter terrain. The grayscale shaded relief data were derived from The National Map Small-Scale Collection (, formerly called National Atlas of the United States. Elevation data were derived from the 3D Elevation Program, (formerly called the National Elevation Dataset), and show the terrain at a resolution of 100 meters. The 3DEP is a raster product assembled by the U.S. Geological Survey, designed to provide national elevation data in a seamless form with a consistent datum, elevation unit, and projection. Data corrections made in the 3DEP assembly process minimize artifacts, permit edge matching, and fill sliver areas of missing data. More information on 3DEP can be found at
