Barrow Area Remote Sensing - Digital Elevation Model



This is a Digital Elevation Model (DEM) of the Barrow Biocomplexity study area. Light Detection and Ranging (LIDAR) data were acquired by AeroMetric at an altitude of approximately 600 meters above mean terrain using an Optech 70 kHz Airborne Laser Terrain Mapper (ALTM 30/70) on board a twin engine Cesna 310 aircraft. The system was configured with a differential global positioning system (DGPS) and a 200 Hz inertial measurements system (IMU) that were used to improve the accuracy of ground data.
