The capability to identify damage level of building due to destructive earthquake from RS image depends on the sensor type (for example optical or SAR) and spatial resolution. It is usually estimated by considering the object size and the pixel size, the number of pixels the object covers. Such comparison does not show effective capability of damage grade identification. The authors have developed...
The synthetic aperture radar (SAR) plays an important role in earthquake emergency response because of its all-time and all-weather imaging capabilities. On April 14, 2010, an MS7.1 earthquake occurred in Yushu county, Qinghai province of China, causing a lot of buildings collapsed. In this paper, the building damage in Yushu city due to the earthquake was assessed quantitatively using high-resolution...
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...
