摘要

According to the National Airport standards,this article has looked over the height of 180000 buildings in the airfield control height region of Cencun Airport(about 123.6 sq.km)for thefirst time.In the paper,based on the planning&approving data and ADS40 aerial survey data,GIS spatial analysis,ADS40 stereo-altimetry technology,field digital measurement and 2D/3D visualization are used synthetically to achieve the results above.Furthermore,the quantity and spatial distribution of over theoretical height buildings are clarified,which is significant to review the airfield height management and to guide the regulatory plan of Tianhe Intellectualized Business District.
