Title: Canopy 2019
Geospatial Data Presentation Form: raster digital data
Description:
Abstract: Developed using LiDAR and imagery collected in the summer of 2019. Canopy was detected using a combination of normalized difference vegetation index (NDVI) from the imagery and feature heights from LiDAR. Geometric post-processing was used to clean up errors and noise (i.e., electrical lines above green vegetation). Date of last data update: 2022-06-22 This is official RLIS data.
