Abstract

The collection comprises over 120,000 maps, including some 15-minute quadrangle maps compiled by the U.S. Army Corps of Engineers, National Parks and Monument maps, River Survey maps, and selected Federal Highway Administration county planning maps. The collection will continue to grow as other types of maps are added.

Key minerals in energy transmission

The electrical grid relies on minerals with unique properties to transform, transmit, and convert electricity. Transmission needs are growing—to support the expansion of data centers and link diverse energy resources into the grid. This expansion will require greater quantities of minerals. Although some minerals are produced in the United States, the United States relies on imports for others. This infographic shows the key minerals that support energy transmission, and how reliant the United States is on imports for these minerals.

3D Elevation Program—Hawaii

Using 3D Elevation Program data, a modern illustration of each State's landscape showcases its elevation differences in vivid detail. Each State has been consistently adjusted and colorized according to its highest and lowest elevations, accentuating differences even in States with low relief. To further emphasize landforms, shaded relief has been added on top of the elevation colors.
