Grid-level (e.g. digital surface models, canopy height models) and tree-level forestry products (e.g. crown-level metrics) derived from Airborne Lidar Scanning data from USGS 3D Elevation Program, NOAA Coastal Topographic Lidar, NSF OpenTopography and other sources.
– USGS 3D Elevation Profile Forest Structure Metrics
Workflow to process high-resolution airborne lidar data from the USGS 3D Elevation Program to map forest ground surface elevation, canopy height, and structural metrics such as canopy cover and tree height distribution.
– NOAA Coastal Topographic Lidar Forest Structure Metrics
Workflow to process NOAA coastal airborne lidar surveys to map forest canopy height and structure in coastal and near-shore environments, including surface models, canopy cover, and terrain-normalized height metrics.
