Abstract :
Remote sensing imageries with high resolution provide abundant information for landslide detection. It is vcry important for hazard investigation and mapping in limestorne area with complex landform. Object-oriented technology is one of these methodologics to extract thematic information from high solution remote sensing imageries. This paper takes Jiweishan limestone area as a case to detect landslide with object-oriented technology and change detection combined with analysis features of NDVI, NDGI, LenthWidth and etc in ALOS images. Land cover change direciton is a sensitive way to detect presumable landslid. Landslid usually bring bare land and blocked land. Jiweishan is a typical landslide in inclined bedding limestorn area which can be well and truly detected in this method.
