2010 UMRS Color Infrared Aerial Photo Mosaic - Mississippi River, Pool 3

The Upper Mississippi River Restoration-Environmental Management Program (UMRR-EMP) partnered with the U.S. Fish and Wildlife Service (USFWS) Region 3 to collect 2010 digital color infrared (CIR) aerial photography of Pools 1-13, Upper Mississippi River and Pools Alton–Marseilles, Illinois River at 8”/pixel and 16”/pixel respectively using a mapping-grade Applanix DSS439 digital aerial camera. The photography shall be at a minimum accuracy of 5-10 meters and allow for the development of orthorectified photo mosaics by U.S. Geological Survey – Upper Midwest Environmental Sciences Center (USGS-UMESC) for all or portions of the coverage area. The flights occurred during times of peak vegetation biomass, typically from late August through early September. The primary use of this photography is for the development of Land Cover / Land Use (LCU) databases of the UMRS by the USGS-UMESC. The photography and LCU databases are used in support of all stages of HREP project development and monitoring. In addition, the photography and maps are used for research and monitoring efforts conducted by the LTRM component in support of UMRR-EMP. The imagery is served over the internet as orthorectified pool mosaics by USGS-UMESC.密西西比河上游修复-环境管理项目（Upper Mississippi River Restoration-Environmental Management Program, UMRR-EMP）与美国鱼类及野生动物管理局（U.S. Fish and Wildlife Service, USFWS）第三区域展开合作，于2010年采集了覆盖密西西比河上游1-13号航段以及伊利诺伊河奥尔顿-马赛利斯航段的数字彩色红外（CIR）航空摄影影像，两类影像的地面采样分辨率分别为8英寸/像素与16英寸/像素，采集设备为测绘级Applanix DSS439数字航空相机。该影像的平面定位精度不低于5至10米，可支持美国地质调查局-中西部环境科学中心（U.S. Geological Survey – Upper Midwest Environmental Sciences Center, USGS-UMESC）对全部或部分覆盖区域制作正射影像镶嵌图。飞行作业均安排在植被生物量达到峰值的时段开展，通常为8月下旬至9月上旬。本影像的核心用途为供美国地质调查局-中西部环境科学中心构建密西西比河上游流域系统（UMRS）的土地覆盖/土地利用（LCU）数据库。该影像及土地覆盖/土地利用数据库可支撑HREP项目全流程的开发与监测工作。此外，该影像与配套地图还可用于长期资源监测计划（LTRM）组分开展的、服务于密西西比河上游修复-环境管理项目的研究与监测工作。美国地质调查局-中西部环境科学中心将上述影像以正射航段镶嵌图的形式通过互联网对外提供共享服务。
