- Abstract
Regional urban extraction is an essential process in analyzing urban agglomeration based on GIS and RS.Urban agglomeration will become the main form of urbanization of China in the future .In this paper, we present results from efforts to map urban agglomeration built-up land at 500 m spatial resolution using MODIS and DMSP/OLS data. This research builds a new building index (NBI) to map regional urban based on MODIS and DMSP/OLS data. Then we verify the validity of the new building index using stratified random accuracy assessment method compares with NDBI and IBI.The result shows that new building index has an overall accuracy of 87.25% (k=0.6537),87.50 %( k=0.6713) and 90.50 %( k=0.8022) at the pixel level and a high level of agreement at the city scale (R2>0.9) in Beijing-tianjin-hebei, Yangtze River Delta and Pearl River Delta urban agglomeration.
