Sightline-based GIS model for building height control

A GIS-based model introduces view path and target path to dynamically calculate building height limits, addressing the limitations of traditional fixed viewpoint methods. This innovation generates sight surfaces and efficiently determines height constraints between paths, as demonstrated in Lhasa's urban design around Potala Palace. The approach enhances visual control by representing 3D block areas more accurately than 2D sections or multiple static viewpoints.
