Abstract: Miniature unmanned aircraft vehicle (UAV) is one of the important tools of tornado damage precise survey. UAV can obtain high-precision image and video to analyze the tornado damage characteristics. This paper introduces features and performance of common UAV that using to tornado damage survey, such as UAV selection and related spare parts in the diff erent situations, weather condition, take-off condition, range conf iguration. In addition, this paper summaries the damage survey method of UAV, the four main points to identify damage indicators and the advantages of identifying tornado moving direction and width by using damage survey examples.
