Abstract :
The imaging remote sensing system based on unmanned airship could provide affordable, current and accurate geo-information, which plays a positive role in geological hazards and emergency response, town planning and other field recently. Using low-altitude remote sensing images collected by unmanned airship, we process and interpret the image, and then recheck the correctness of the results through field identification. The whole work flow is proposed, including data acquirement, image processing, interpretation and application. The low-altitude image has a high spatial resolution, which could provide minutiae of hazards. Thematic information of geological hazards shows that: there exist 4 kinds of geological disasters, which distributes along the rivers and roads, centralizing on the slopes. Therefore the image is suitable to be used as data source for geological hazards´ investigation in large scale. Moreover, and our work lays a foundation for remote sensing technology to apply and popularize in investigation of geologic disasters.
