Sample Elevation Models
So that mapmakers and researchers have "common ground" for comparative experimentation, this website offers multi-resolution DEMs, and DEMs of archetypal landforms. Use these data for evaluating terrain visualizations and testing software.
North Atlantic Seafloor Map
This map showcases the exotic bottom features of the North Atlantic Ocean, including abyssal plains, banks, canyons, seamounts, trenches, and the scar-like Mid-Atlantic Ridge. Above the waves, the map offers select coastal cities for reference.
Blue Earth Bathymetry
An edited and smoothed version of GEBCO (General Bathymetric Chart of the Oceans) designed for small-scale mapping of the ocean floor—without unsightly artifacts. It is available as a free GeoTIFF DEM.
Mount Everest 3D Map
A high-oblique view of Mount Everest from the west-northwest. The terrain derives from High Mountain Asia elevation data supplemented with glaciers extracted from a June, 2016, Landsat image. The map is available with and without labels.
Physical Features of the Contiguous US
A map with over 3,000 labels showcasing the mountains, rivers, and lakes of the 48 contiguous US states. Map colors reflect natural environments across the continent from the forested east to the snowcapped Rockies to the desert southwest.
