NASA WERK Lidar - Sierra Nevada (1m, 2022)

1-meter resolution lidar-derived topographic products covering a large portion of the Sierra Nevada mountain range, collected in 2022. This dataset supports forest health monitoring, wildfire risk modeling, snowpack analysis, and biodiversity assessment across California's primary mountain ecosystem.

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.
