The U.S. Geological Survey (USGS) has commissioned Woolpert to collect Quality Level 1 lidar data and conduct ground control surveys throughout Southern California in support of the 3D Elevation Program (3DEP) and The National Map.

Overseen by the USGS National Geospatial Program, 3DEP provides the nation’s first comprehensive, high-resolution topographic elevation data integrated into The National Map. The data will be accessible to local, state and national agencies to consider when making decisions that affect the immediate safety of life, property and the environment, as well as for long-term infrastructure planning.

Woolpert will collect roughly 60,000 km2 of aerial lidar data throughout Inyo County, California, including parts of the Mojave Desert and Death Valley National Park, using a Leica TerrainMapper. QL1 data are collected at eight points per square meter.

“Woolpert has had the honor of supporting USGS’ 3D Elevation Program since its launch nearly a decade ago,” said John Gerhard, Woolpert vice president and program director. “Critical decisions that depend on accurate and available elevation data are being made every day, and we are incredibly proud to continue our support for the U.S. Geological Survey and its commitment to completing the nation’s first-ever baseline of consistent high-resolution elevation data.”

Gerhard added that the data acquired for this project will also support the USGS 3D Hydrography Program (3DHP). The project is underway, and data is expected to be acquired by fall 2024.
