摘要:The Kobe earthquake in 1995 demonstrated an urgent need of developing a change detection mapping system ofbuildings with high temporal accuracy to save people from damaged buildings. An airborne laser scanning system(ALSS) is considered to have the potential of meeting such a need of detecting building changes in 3D shape because ofits capability of direct measurement of ground elevation and short turnaround time.This study employed the data acquired by ALSS at three different occasions to detect changes of buildings in 3D shape.Images generated from a simple processing of these ALSS data clearly showed building changes without omissionerrors, the detection of which, otherwise, would require intensive manual airphoto interpretation. The combination of aCCD array sensor with the laser scanning system also indicated the potential of ALSS for automated orthoimagedevelopment, even though the current system developed in this study still needs further improvement in imagedisplacement correction
