USGS Hill Shade Base Map Service from The National Map

Metadata Updated: November 12, 2020

The USGS Shaded Relief base map service from The National Map was created with data from the 3D Elevation Program (3DEP) for large and medium scales (1:9,028 through 1:1,155,581), and Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) for small scales (1:2,311,162 through 1:295,828,764). 3DEP maintains a seamless dataset of best available raster elevation data, as LIDAR and as digital elevation models (DEMs), for the conterminous United States, Alaska, Hawaii, and Territorial Islands. Resolutions available include 1-meter, 3-meter (1/9-arc-second), 10-meter (1/3-arc-second), 30-meter (1-arc-second), and 60-meter (2-arc-second; only in Alaska). 3DEP also contains coverage of Canada, Mexico, Central America, and the Caribbean at 30-meter (1-arc-second) resolution. 3DEP shaded relief was derived with a multi-directional hillshade technique. Small-scale shaded relief was created with a single-direction hillshade from GMTED2010 global elevation data at 7.5-, 15-, and 30-arc-second resolutions, and resampled further for scales 1:18,489,298 and smaller. Ocean areas are left unfilled for maximum flexibility by end users.
