Research on application of airborne LiDAR measurement technology in glacier scientific observation
As solid reservoirs,glaciers are of great significance for the utilization of water resources and sustainable development of ecosystems in the arid regions of northwest China.It is crucial to conduct scientific research on gla-ciers and explore new technologies and methods for glacier research.Based on the research on application of air-borne LiDAR measurement technology in glacier scientific observation,the authors conducted the feasibility analy-sis and technical method demonstration of glacier aerial measurement from three aspects of aviation measurement experience,meteorological conditions in glacier test areas and aviation equipment.The results showed that the abso-lute errors in the plane and elevation of glacier LiDAR data were mainly≤10 cm,accounting for 86.6%in the X di-rection,86.5%in the Y direction,66.6%in the XY direction,and 90.0%in the Z direction respectively.The error values met the requirements for glacier observation.By this glacier experiment,the feasibility of applying airborne LiDAR measurement technology in glacier scientific observation was verified,breakthroughs in aerial measurement technology were achieved in areas with high altitude,high drop and extreme weather,adding new impetus to the de-velopment of glacier scientific research in China.
