Characterizing Forest Structure Changes and Effects on Snowpack, AZ 2017

Welcome Guest ( Sign In )

Overview

This dataset, located near Flagstaff, AZ, was collected as an NCALM Seed grant for Jonathon Donager, Northern Arizona University, School of Earth Sciences & Environmental Sustainability to support an investigation of leveraging terrestrial laser scanning and structure from motion data for characterizing forester structure changes and the effects on snowpack accumulation and persistence. The requested survey area is located approximately 8 km west and north of Flagstaff, AZ. The polygon encloses approximately 89.7 km².
