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.本数据集为巴罗生物复杂性研究区域的数字高程模型（DEM）。激光雷达（LIDAR）数据由AeroMetric公司采集，采集时飞行高度约为平均地形上方600米，搭载设备为奥普泰克70千赫机载激光地形测绘仪（ALTM 30/70），搭载平台为双引擎塞斯纳310飞机。该系统配备差分全球定位系统（DGPS）与200赫兹惯性测量系统（IMU），用于提升地面数据的采集精度。
