2011 UMRS Color Infrared Aerial Photo Mosaic - Mississippi River, Pool 26

The Upper Mississippi River Restoration-Environmental Management Program (UMRR-EMP) partnered with the U.S. Fish and Wildlife Service (USFWS) Region 3 to collect 2011 digital color infrared (CIR) aerial photography of Pools 14 - Open River South, Mississippi River and Pools Dresden - Lockport, Illinois River at 16”/pixel 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，于2011年采用测绘级Applanix DSS439数字航空相机，以16英寸/像素的分辨率，采集了密西西比河14号航道-南岸开阔河段以及伊利诺伊河德累斯顿-洛克波特航道段的数字彩色红外（CIR）航空影像。该影像定位精度不低于5-10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）针对全部或部分覆盖区域制作正射校正影像镶嵌图。航摄作业于植被生物量峰值期开展，通常为8月下旬至9月上旬。本影像的核心用途为支持USGS-UMESC构建密西西比河上游航道系统（Upper Mississippi River System, UMRS）的土地覆盖/土地利用（LCU）数据库。该影像与LCU数据库可用于支撑HREP项目开发与监测的全流程工作。此外，影像及配套制图成果还可用于LTRM相关部门为支持UMRR-EMP开展的各项研究与监测工作。美国地质调查局——中西部上游环境科学中心（USGS-UMESC）通过互联网以正射校正航道镶嵌图的形式对外提供该影像数据服务。
