Abstract：
Based on the spectral characteristics of the impervious materials, a new index, normalized difference impervious surface index (NDISI), for enhancing and extracting ISA using a band combination method, is put forward. The applications of the index in landsat and ASTER images show that the new index can efficiently enhance ISA while suppress background noise. It can be used in a fast extraction of ISA in a large region.
