　三峡库区航摄影像数据采集是重庆市与国家测绘局、湖北省合作建设的三峡库区综合信息空间集成平台的重要内容。日前，国家测绘局历时5个月，用三台相机采集完成包括整个库区范围在内的1.3万平方公里航摄影像数据，数据分辨率高达0.2米。中国工程院院士刘先林称这是“中国数码航摄史之最”。此次航摄影像基本覆盖了重庆市巫山、奉节、云阳、开县、万州、忠县、丰都、涪陵、江津等22个区县建设密集区，以及沿长江两岸5公里范围，为库区环保监测、森林分析、城乡规划、防灾救灾、应急救援等各领域工作开展提供了可靠、翔实的基础信息保障。此次航摄影像数据采集，也是重庆市首次大规模、广范围地获取整个三峡库区基础地理信息数据，为库区可持续发展、“五个重庆”又好又快建设奠定了基础。

Air photography, like the Three Gorges reservoir area in Chongqing data acquisition with the National Mapping Bureau, co-construction of the Three Gorges reservoir area in Hubei Province comprehensive information integration platform for an important part of space. Recently, the State Bureau of Surveying and Mapping lasted for 5 months, with three cameras, including the entire collection to complete the scope of the reservoir area of 13,000 square kilometers including photographers such as flight data, the data resolution of up to 0.2 meters. Chinese Academy of Engineering, Xian-Lin Liu called it a "digital aerial History of China the most." The Air photography such as basic coverage Chongqing Wushan, Fengjie, Yunyang, Kaixian, Wanzhou, Zhongxian, Fengdu, Fuling, Jiangjin and other construction-intensive areas in 22 districts and counties, as well as the range of 5 kilometers along the Yangtze River for the reservoir area environmental monitoring, forest analysis, urban and rural planning, disaster prevention and disaster relief, emergency rescue and other fields of work carried out to provide a reliable and detailed basic information security. The flight photography as data acquisition, is also the first large-scale Chongqing, wide range of access to the entire Three Gorges basic geographic information and data for the reservoir area of sustainable development, "five Chongqing" laid the foundation for the building and fast.
