UMRS LTRMP 2010/11 LCU Mapping -- Pool 5a

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).

针对美国密西西比河上游流域1-13号航段以及伊利诺伊河奥尔顿-马赛尔斯段航区的航空摄影照片，于2010年8月采用测绘级Applanix DSS 439型数字航空相机，分别以8英寸/像素、16英寸/像素的分辨率采集，影像采用彩色红外（CIR）波段。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号航段-南开放河段以及伊利诺伊河德累斯顿-洛克波特段航区的彩色红外航空摄影照片。所有彩色红外航空摄影照片均经过正射校正、影像镶嵌与压缩处理，并通过UMESC互联网站点对外提供服务。本次采用31类LTRMP植被分类体系，对彩色红外航空摄影照片完成了解译与自动化处理。2010/2011年度LCU数据库由具备资质且经过专业培训的人员，依据书面化标准作业流程编制，并通过严格的质量控制（QC）保障体系确保数据可靠（NBS, 1995）。
