Challenging High-accuracy Airborne Lidar Mapping Mission in Greenland

Denmark-based company机载LIDAR映射A / sconducted a demanding data acquisition project in the summer of 2019. The purpose of the resulting data was to enable digital terrain models and to update existing base maps of the cities Nuuk, Sisimiut, Ilulissat, Qaqortoq and Aasiaat in Greenland. The northernmost city is Ilulissat, which is situated 350km north of the Arctic Circle. Several anomalous parameters were involved in the planning of the mission in comparison to typical Lidar aerial mapping missions. The arctic climate, the remote location and the size of the island necessitated arctic survival skills as well asarctic-proofcommunication equipment. Furthermore, AVGAS fuel for the aircraft used is a scarce commodity in Greenland.

The airborne platform chosen was the Cessna C337 Skymaster, a rare multi-engine aircraft with centreline thrust, which provides a reliable platform to house the cameras and Lidar equipment required for the mission.

此外，C337配备了脱冰和防冰系统，确保冷北极区域的优异安全性。使命要求涉及在充满挑战的地形上以上地面上方的1,500英尺处获得的数据。大量的变异性描绘了北极天气，天气状况贫困延长了使命。允许在遇到格陵兰提供的一些非凡的自然体验的情况下进行的天气。在这些日子里，该飞机还被证明是一个优秀的观光仪器，在其他空中鲸鱼和冰川观看中存在。对于基于丹麦的企业，该访问对王国的自主部分熟悉更熟悉。

According to the Airborne Lidar Mapping CTO, the mission was a great experience and success. “It is a statement to the fact that Airborne Lidar Mapping A/S can provide high-quality, dependable and dedicated service to customers anywhere in the world." The mission pilot stated: "Greenland was breathtakingly beautiful, a true pleasure and challenge for an aviator."
