Access USGS 3DEP lidar point cloud data for a forest inventory area of interest
domain: apps.nationalmap.gov · 4 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
For small interactive pulls, use the TNM Downloader (apps.nationalmap.gov/downloader/) or LidarExplorer (apps.nationalmap.gov/lidar-explorer/#/) to select an AOI and download point clouds/DEMs
For programmatic discovery of available datasets/metadata, call the TNM Access API at apps.nationalmap.gov/tnmaccess
For bulk/large-volume access, pull directly from the public AWS S3 mirror: aws s3 ls --no-sign-request s3://usgs-lidar-public/ (free, EPT format, no AWS account needed)
For full raw-LAZ coverage not mirrored in the free bucket, use the Requester Pays bucket s3://usgs-lidar with --request-payer requester (bills your own AWS account), both in us-west-2
Known gotchas
The Requester Pays bucket incurs real AWS charges billed to your account
The free EPT mirror does not cover 100% of the requester-pays projects, so some tiles/CRS combinations are missing
Coverage, density and vintage vary patchily by project since 3DEP is a rolling collection effort, not a uniform national dataset
