UMRS LTRMP 2010/11 LCU Mapping -- Pool 19

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).

2010年8月，采用测绘级Applanix DSS 439数字航空相机，采集了密西西比河上游水系1-13号池区以及伊利诺伊河奥尔顿-马赛尔斯池区的彩色红外（Color Infrared, CIR）航空影像，影像分辨率分别为8英寸/像素与16英寸/像素。2011年8月，使用同款相机采集了密西西比河上游14号池区-南部开放河段以及伊利诺伊河德累斯顿-洛克波特池区的彩色红外航空影像，采集分辨率统一为16英寸/像素。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。该批彩色红外航空影像采用31类LTRMP植被分类体系完成解译与自动化处理。2010/2011年度LCU数据库由具备资质且经过系统培训的专业人员依据成文标准作业流程编制，并经过严格的质量控制（QC）保障（NBS，1995）。
