USGS 3DEP · BROWSER LIDAR EXPLORER
Explore LiDAR anywhere
Search a place, draw a rectangle, and scan public point-cloud coverage.
COVERAGE & SCAN
Choose an area on the map
Use the rectangle tool, then select Scan Area. Each side may be up to 2,000 m; device-aware point limits prevent oversized downloads.
POINT-CLOUD VIEWER
Waiting for real EPT points
Display sampling only limits rendered points. Retrieved LAZ attributes and in-box point data remain separate from the display sample.
POTENTIAL STRUCTURES
No candidates yet
Heuristic evidence only; candidates are not confirmed buildings.
Run a scan to see candidate structure evidence.
Owner review panel
Every visitor's scan saves candidate markers to shared storage. Sign in with the configured owner Google account to remove or restore markers. Removed locations stay suppressed when a later scan finds them again.
Scan Diagnostics
Measurements are generated automatically for each scan. The browser reports only memory exposed by its APIs. Z and ground-relative heights remain in LAS Z units until the vertical reference is verified.
