Barrow Area Remote Sensing - Digital Elevation Model, Version 1.0

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.

这是巴罗生物复杂性研究区域的数字高程模型（Digital Elevation Model，DEM）。光探测与测距（Light Detection and Ranging，LIDAR）数据由AeroMetric公司采集：数据采集时，双引擎塞斯纳310型飞机搭载Optech 70 kHz机载激光地形测绘仪（Airborne Laser Terrain Mapper，ALTM 30/70），飞行高度约为平均地形以上600米。该系统配置了差分全球定位系统（Differential Global Positioning System，DGPS）和200赫兹惯性测量系统（Inertial Measurement System，IMU），用于提升地面数据的精度。
