Study on the fractal analysis of SAR images and its application to the extraction of seismic damage of 2010 Yushu, China Ms=7.1 earthquake

The SAR image can be acquired without the affection of cloud or rain and the limitation of sunlight, so it is widely used in many fields, especially in the disaster management. The paper is concentrated on the research of the method to extract disaster information quickly from SAR images, which is important and useful for emergency remote sensing processing. The fractal analyzing methods are described and applied to extract the building damage of 2010 Yushu Ms 7.1 earthquakes from SAR images. The results are compared with the interpretation of building damage from the high resolution airborne and satellite optical images.
