UMRS LTRMP 2010/11 LCU Mapping -- Pool 09

Aerial photographs for Pools 1-13 Upper Mississippi River System and Pools, Alton-Marseilles, Illinois River were collected in color infrared (CIR) in August of 2010 at 8”/pixel and 16”/pixel respectively using a mapping-grade Applanix DSS 439 digital aerial camera. In August 2011, CIR aerial photographs for Pools 14-Open River South, Upper Mississippi River and Pools Dresden-Lockport, Illinois River were collected at 16”/pixel with the same camera. All CIR aerial photos were orthorectified, mosaicked, compressed, and served via the UMESC Internet site. The CIR aerial photos were interpreted and automated using a 31-class LTRMP vegetation classification. The 2010/11 LCU databases were prepared by or under the supervision of competent and trained professional staff using documented standard operated procedures and are subject to rigorous quality control (QC) assurances (NBS, 1995).本数据集包含以下航空影像采集工作：2010年8月，采用测绘级Applanix DSS 439数字航空相机，分别以8英寸/像素、16英寸/像素的分辨率，采集了密西西比河上游航道1-13池以及伊利诺伊河阿尔顿-马赛利斯航道池的彩色红外（Color Infrared, CIR）航空影像；2011年8月，采用同款相机，以16英寸/像素的分辨率，采集了密西西比河上游14号航道-南部开放河段以及伊利诺伊河德累斯顿-洛克波特航道池的彩色红外航空影像。所有彩色红外航空影像均经过正射校正、影像镶嵌与压缩处理，并通过UMESC互联网站点对外提供服务。本次研究采用31类LTRMP植被分类体系完成彩色红外航空影像的解译与自动化处理。2010/2011年度LCU数据库由合格且经过培训的专业人员编制或在其监督下完成，编制过程遵循成文的标准作业程序，并经过严格的质量控制（Quality Control, QC）保障，相关工作引用了NBS, 1995的规范。
