2011 UMRS Color Infrared Aerial Photo Mosaic - Mississippi River, Pool 24

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，简称UMRR-EMP）与美国鱼类及野生动物管理局（U.S. Fish and Wildlife Service，简称USFWS）第三大区开展合作，采用测绘级Applanix DSS439型数字航空相机，以16英寸/像素的分辨率，采集了2011年度密西西比河14号航道-南开放河段以及伊利诺伊河德累斯顿-洛克波特航道的彩色红外（CIR）数字航空摄影数据。该摄影数据的定位精度不低于5~10米，可用于美国地质调查局-上中西部环境科学中心（U.S. Geological Survey – Upper Midwest Environmental Sciences Center，简称USGS-UMESC）制作全部或部分覆盖区域的正射影像镶嵌图。本次飞行作业时段选在植被生物量达到峰值的时期，通常为8月下旬至9月上旬。此类摄影数据的核心用途为供美国地质调查局-上中西部环境科学中心构建密西西比河上游系统（Upper Mississippi River System，简称UMRS）的土地覆盖/土地利用（LCU）数据库。该航空摄影数据与土地覆盖/土地利用数据库可支撑HREP项目全阶段的开发与监测工作。此外，该航空摄影数据及衍生地图可用于LTRM分支部门为支持密西西比河上游修复-环境管理计划所开展的各类研究与监测工作。美国地质调查局-上中西部环境科学中心通过互联网以正射影像航道镶嵌图的形式对外提供此类影像数据。
