Abstract

Automated Feature Extraction from Aerial Imagery for Forestry Projects
Track: Forestry
Authors: Brad Weigle

ModelBuilder was used to create 3D enabled data layers for Forest inventories from point clouds and rasters derived from stereo aerial imagery. Processes included updating 10m DEMs using terrain elevations from bare areas, deriving stream characteristics and flood plains in riparian areas, and canopy height/cover. Additional models utilized FIA data to identify and map areas with large trees. Future work includes tapping into film vaults to process imagery dating back to the 1930's.
