Paper Abstract

It is the difficulties to radar image interpretation, present remote sensing investigation and assessment of geohazard is mainly dependent on the high-resolution optical images, resulting in limited ability to extract surface information. The main advantage of radar is that it provides superior penetration capability under any type of weather condition, and can be used in the day or night time, rich image information and so on for the risk assessment of landslide, especially in geohazard emergency; optical image cannot match this advantage. The use of the "5.12" earthquake-induced landslide hazard for the research prototype, elaborate unique advantages and technical support role of remote sensing technology in landslide investigation and risk assessment, from the basic terrain data acquisition, disaster background analysis, interpretation of landslide hazard, monitoring, mapping, etc. Use of airborne and satellite radar remote sensing and Multi-source data to composite analysis of hazard information, indicates that the better interpretation effect by field investigation. The research results of this paper have great reference value to emergency disaster prevention and reduction of occurred frequent and dangerous geohazard.
