What is LiDAR USGS?

Light Detection and Ranging (lidar) is a technology used to create high-resolution models of ground elevation with a vertical accuracy of 10 centimeters (4 inches).

How do I get a lidar map?

LiDAR data from airborne sensors are available through The National Map Download Client. These data are discrete-return, classified point-cloud data provided in LAS format. You can also use the Earth Explorer (USGS). Enter LiDAR in the Data Sets tab search window, or find the checkbox under Digital Elevation.

What is a 1/3 arc second DEM?

1/3 arc-second – This is the highest resolution seamless DEM dataset for the U.S. with full coverage of the 48 conterminous states, Hawaii, and U.S. territories. Alaska coverage is partially available now and is being expanded to statewide coverage as part of the Alaska Mapping Initiative.

What can you do with LiDAR data?

LIDAR can also be used in any situation where the structure and shape of Earth’s surface needs to be known, and can even measure some gases and particles in the atmosphere. Its versatility and high resolution give it applications in archaeology, climate monitoring, city planning, meteorology, mining, and much more.

What is the resolution of 3DEP?

This is a tiled collection of the 3D Elevation Program (3DEP) and is 1/3 arc-second (approximately 10 m) resolution. The 3DEP data holdings serve as the elevation layer of The National Map, and provide foundational elevation information for earth science studies and mapping applications in the United States.
