Surveying of Tall Buildings over Theory Height within Obstacle Free Airspace

Abstract

According to the National Airport standards, this article has looked overthe height of 180000 buildings in the airfield control height region ofCencun Airport (about 123.6 sq. km) for the frst time. In the paper, basedon the planning & approving data and ADS40 aerial survey data, GISspatial analysis, ADS40 stereo-altimetry technology, field digital measurement and 2D/3D visualization are used synthetically to achieve theresults above. Furthermore, the quantity and spatial distribution of overtheoretical height buildings are clarifed, which is signifcant to reviewthe airfeld height management and to guide the regulatory plan of TianheIntellectualized Business District.
