2010 UMRS Color Infrared Aerial Photo Mosaic - Mississippi River, Pool 12

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-环境管理计划（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）第三大区开展合作，采用测绘级Applanix DSS439数字航空相机，分别以8英寸/像素与16英寸/像素的分辨率，采集了密西西比河上游1-13号航段以及伊利诺伊河奥尔顿-马赛勒斯航段2010年的数字彩色红外（color infrared，CIR）航空摄影影像。该航空摄影数据的精度最低可达5至10米，可支持美国地质调查局-中西部上游环境科学中心（U.S. Geological Survey – Upper Midwest Environmental Sciences Center，USGS-UMESC）针对覆盖区域的全部或部分范围制作正射影像镶嵌图。飞行拍摄时段选定在植被生物量峰值期，通常为8月下旬至9月上旬。该航空影像的核心用途是供USGS-UMESC构建密西西比河上游流域的土地覆盖/土地利用（Land Cover / Land Use，LCU）数据库。上述航空影像与LCU数据库可支撑HREP项目开发与监测的全阶段工作。此外，该航空影像与配套地图还可用于LTRM部门为支持UMRR-EMP开展的研究与监测工作。USGS-UMESC将该影像以正射航段镶嵌图的形式通过互联网对外提供服务。
