NASA WERK Lidar - Los Angeles (1m, 2023)

1-meter resolution lidar-derived topographic products covering the greater Los Angeles area, collected in 2023 as a pre-fire baseline. This dataset serves as a reference for comparison with post-wildfire surveys and supports urban planning, flood risk modeling, and ecosystem assessment across the LA basin.

Bands: Digital Terrain Model (DTM), Digital Surface Model (DSM), Canopy Height Model (CHM), Slope, Aspect.

This dataset is part of the NASA Wildfire, Ecosystem Resilience, and Risk Assessment (WERK) initiative — a collaborative effort between NASA, the California Natural Resources Agency (CNRA), and the California Air Resources Board (CARB). Products are derived from 3D airborne lidar point cloud data from the USGS 3D Elevation Program (3DEP) and include elevation, slope, aspect, canopy height, canopy cover, and height percentiles. All files are in Cloud-Optimized GeoTIFF (COG) format.
