Unmanned aerial vehicle emergency remote sensing
Unmanned aerial vehicle (UAV) remote sensing can make up for the shortcomings of traditional emergency methods with its remarkable characteristics of rapidity, macroscopic and dynamic. We can not only observe the disaster-stricken areas, the disaster situation and the air, soil, vegetation and water quality caused by the disaster from a macro perspective, but also provide decision-making basis for emergency rescue, disaster assessment and post-disaster management. We can also track and monitor the development of sudden environmental pollution events in real time and formulate treatment measures in time to reduce the losses caused by pollution. With the comprehensive application of remote sensing technology, information technology and communication technology, remote sensing technology can serve environmental protection departments in many aspects, such as environmental emergency response, pollution source management, environmental quality evaluation and river basin environmental monitoring, which greatly improves the management, supervision and service level of environmental protection departments. However, in order to do this, the UAV must meet the following conditions: the advantages of UAV emergency remote sensing application were first reflected in the Wenchuan earthquake, which was accompanied by wind and rain, resulting in the inability to obtain satellite data, the difficulty for large aircraft to fly, and the inability to obtain a clear image of the disaster area, making the disaster area a blind spot! Unmanned aerial vehicle (UAV) obtains high-resolution digital images in real time by flying under clouds and between clouds, which provides first-hand support information for UAV earthquake relief! The subsequent Yushu earthquake drone also played a key role.
Emergency remote sensing of debris flow disaster relief and flood disaster. Oil spill, serious environmental pollution, public safety accidents, etc.
