摘要
本文以通化三源浦机场净空限制面评估为例,用DEM数字高程模型与机场净空空域范围叠加,阐述如何利用DEM和机场净空限制面高度快速评估出机场净空区域内单点障碍物对空域的影响,以防止障碍物对机场净空空域的入侵,保障飞机的飞行安全和机场空域资源的有效使用.
Abstract
This paper takes Tonghua Sanyuanpu Airport clearance limiting surface assessment as an example. Based on the superposi-tion of DEM digital elevation model and airport clearance airspace range,this paper uses DEM and the height of airport clearance lim-iting surface to quickly evaluate the impact of single point obstacles on the airspace in the airport clearance area,so as to prevent the intrusion of obstacles on the airport clearance airspace and ensure the flight safety of aircraft and the effective use of airport airspace re-sources.
