Lake Isabella Lidar Collection, CA 2015

Airborne LiDAR data was acquired by CRREL on 21 August 2015 over Lake Isabella and the Lake Isabella Dam, California as part of a coincident regional study. These data were collected using an airborne laser scanning (ALS) system comprised of a Riegl Q680i full-waveform LiDAR sensor, an Applanix POS AV INS system, and custom designed hardware and aircraft integration components. The system was installed in a Partenavia P.68, with an average collection AGL of 2,600' and airspeed of 90 knots. A total of 19-flight-lines were collected during a single flight, with 50% overlap of laser swath coverage, given a 60 deg across track field-of-view.

机载激光雷达（Airborne LiDAR）数据由寒区研究与工程实验室（CRREL）于2015年8月21日在加利福尼亚州伊莎贝拉湖及伊莎贝拉湖大坝区域采集获取，作为一项同步区域研究的组成部分。本次数据采集采用的机载激光扫描（Airborne Laser Scanning, ALS）系统，由Riegl Q680i全波形LiDAR传感器、Applanix POS AV惯性导航系统（Inertial Navigation System, INS）以及定制化硬件与飞机集成组件构成。该系统搭载于帕特纳维亚P.68型飞机，平均离地高度（Above Ground Level, AGL）为2600英尺，航速为90节。单次飞行中共采集19条飞行航线，激光条带覆盖范围的重叠率为50%，系统沿飞行轨迹垂直方向的视场角为60度。
