Acquiring height distribution information about high-rises in Beijing using shadow in SPOT-5

摘要：

Shadow in panchromatic band of some high spatial resolution remotely-sensed data can be worked at building height information extraction.This paper introduced an operational method to undertake height distribution information extraction using SPOT-5 panchromatic and multi-spectral data.Whether such a method is feasible and sensibilities of result to some influential factors are analyzed.Then,the method is applied to process SPOT -5 data of Beijing in year 2004 and 2007.Height distribution result shows that high-rise building within Chaoyang District contributes a lot to height growing of the whole city.
