| Abstract: | Based on an analysis of the relationship between the building heights and the shadows in IKONOS image, this paper presents the principle and the method for the estimation of building heights in a city from the shadows of an image. A fairly accurate result was achieved in applying this technique to extracting building height information from Zhongguancun area, Tiantan Park and Beihai Park in Beijing. The achievements made demonstrate the great application potential of satellite remote sensing in garden designing and numerical simulation of the urban garden environment. |
