Welcome Guest   ( Sign In )

Overview

This survey covers portions of Hawaii Volcano National Park on the Big Island of Hawaii. This dataset was contracted by the U.S. Geological Survey (USGS) via Quantum Spatial, Inc., and acquired by GEO1 and Windward Aviation. GEO1 conducted the collection activity using a Windward Aviation Hughes 500 helicopter with a dual LiDAR scanning system that utilized two Riegl VUX-SYS scanners operated as one unit. The dataset was acquired through 11 lifts, and comprises 4 distinct Areas of Interest (AOIs). The survey area covers 105 square kilometers. Dataset obtained from the USGS Kilauea LiDAR website. Please refer to that site for additional information.
