2011 UMRS Color Infrared Aerial Photo Mosaic - Illinois River, Dresden Pool

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（United States Fish and Wildlife Service，USFWS）第三大区合作，采用测绘级Applanix DSS439数字航空相机，以16英寸/像素的地面采样间隔，采集了2011年度密西西比河14号河段-南部开放河道段以及伊利诺伊河德累斯顿-洛克波特河段的数字彩色红外（Color Infrared，CIR）航空摄影数据。该航空摄影数据的最低定位精度为5至10米，可支持美国地质调查局-中西部环境科学中心（United States Geological Survey – Upper Midwest Environmental Sciences Center，USGS-UMESC）制作覆盖区域全部或部分范围的正射影像镶嵌图。飞行作业选取在植被生物量峰值时段开展，通常为8月下旬至9月初。本数据集的核心用途为供USGS-UMESC构建密西西比河上游水系（Upper Mississippi River System，UMRS）的土地覆盖/土地利用（Land Cover / Land Use，LCU）数据库。该航空影像与LCU数据库可支撑HREP项目全阶段的开发与监测工作。此外，这些影像及地图还可用于LTRM（Long-Term Resource Monitoring）相关工作单元开展的、支撑UMRR-EMP的研究与监测工作。美国地质调查局-中西部环境科学中心（USGS-UMESC）通过互联网提供该影像的正射影像河段镶嵌图服务。
