3D Elevation Program

Home

To respond to growing needs for high-quality elevation data, the 3D Elevation Program (3DEP) is systematically collecting 3D elevation data during an 8-year period in the form of light detection and ranging (lidar) data over the conterminous United States, Hawaii, and the U.S. territories.

The 3D Elevation Program—Supporting California's Economy

IntroductionCalifornia faces unprecedented challenges presented by shifting weather patterns that are defining a “new normal.” The result has been extreme weather events, prolonged drought, flooding, and debris flows. These conditions drive severe tree mortality, increase wildfire occurrence and intensity, reduce water availability, and hasten...

The 3D Elevation Program—Flood risk management

Flood-damage reduction in the United States has been a longstanding but elusive societal goal. The national strategy for reducing flood damage has shifted over recent decades from a focus on construction of flood-control dams and levee systems to a three-pronged strategy to (1) improve the design and operation of such structures, (2) provide more...

The 3D Elevation Program national indexing scheme

The 3D Elevation Program (3DEP) of the U.S. Geological Survey (USGS) acquires high-resolution elevation data for the Nation. This program has been operating under an opportunity-oriented approach, acquiring light detection and ranging (lidar) projects of varying sizes scattered across the United States. As a result, the national 3DEP elevation...
