Description
USGS 3DEP LiDAR Point Clouds provide two realizations of high-resolution elevation data for the conterminous United States, Hawaii, and U.S. territories. The data was collected over an 8-year period by the U.S. Geological Survey's 3D Elevation Program. One resource is a public access, full-density streamable format, while the other is a more complete, requester-pays version of the original raw data.
Use Cases
Generate high-resolution digital elevation models based on the full-density LiDAR point clouds.
Analyze terrain for disaster response and mitigation planning based on the national elevation coverage.
Train machine learning models for land cover classification using the 3D point cloud data.
Conduct watershed and hydrological analysis based on the detailed elevation information.
Strengths
Data collection covers the conterminous United States, Hawaii, and U.S. territories.
Collection was planned over an 8-year period, suggesting a systematic acquisition program.
Provides two data realizations: a public, streamable format and a more complete, requester-pays version.
