Abstract:
For this project canopy height data were derived from 30 cm imagery using Semi-Global Matching for all riparian areas found within the Apacha-Sitgreaves National Forest and used in mapping tree size. Watershed tools were used to identify tree location and create a canopy height model (CHM). The CHM and other predictor variables from imagery were used to segment the study area into objects with similar characteristics for use in vegetation mapping. Vegetation mapping attributes were then added to each segment as classified by Random Decision Forest classifier. A 20 meter buffer from the RMAP boundary was created as a study area. Two final products are presented, this product that has been clipped to the RMAP boundary with map features designed to meet a minimum size of .25 hectares and a second that includes the 20 meter buffer and has no minimum map unit.
Purpose:
This feature class contains attribute information from four different vegetation maps (Lifeform Type, Leaf Retention Type, Canopy Cover, and Size Class) and statistics on NDVI and lidar and phodar.
