Urban building density estimation using high resolution SAR imagery

Urban building density has always been an important indicator for city planning,land management and resident density evaluation.It hasn't until recently that SAR data with high resolution of one meter or even finer grid can be easily retrieved,thus making it possible to extract urban fabric like building density from SAR imagery.An effective method for computing urban building density from high resolution SAR images is proposed.This method has three main steps:building detection,building density estimation and amendment.The experiment results for TerraSAr-X images show that the proposed method has a good performance.
