| Abstract: | This paper introduce the digital RS system based on ultralight aviation platform, which used 4K×5K plane an＇ay camera to obtain large scale true color aerial imagery of Wenchuan earthquake region on low altitude, with the advantage of high-resolution and high- quality. It can make up the disadvantage of traditional aerial photography technique, less dependence on airport and weather. And it has the characteristics of management convenient, process fast, low costs. It is an important means of technology on low altitude and small area, emergency services and security of surveying and mapping. This system is extensive used on images acquired quickly of the affected small towns and villages, mainly takes on the role of DOM production faced to disaster and 1：2000 mapping of reconstruction after the disaster. The production quality is good, resolution is high, image information is rich, and interpretation to disaster is more accurate and detailed. We could view housing collapsed, and even tile damaged, road subsidence and so on. Meanwhile, it has clear performance on mud-rock flow, landslide, landslide lake, etc., and meets the requirements of surveying and mapping and disaster management. |
