Abstract
Unmanned aerial vehicle remote sensing (UAVRS) technique was applied to emergency monitor Cocktail Mountain landslip geological hazard in Wulong county of Chongqing. The paper analyzes methods of accessing and processing digital image data in mountainous area and its application to emergency response management of geological hazard. The conclusion shows that UAVRS can access quickly high-precision remote sensing digital map and supply newly and explicit data for emergency decision. Combing with GIS spatial analyst modeling, UAVRS can assess high-speed hazard and provide base of allocating relief supplies. UAVRS integrating GIS can bring up potential and secondary disaster points for guaranteeing safety of personnel and property. UAVRS can also provide hazard information timely and exactly for pacifying the public to avoid panic. So UAVRS technique can provide technical support for emergency response management of geological hazard.
