UMRS LTRMP 2010/11 LCU Mapping -- Pool 12

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).本数据集包含密西西比河上游水系1-13号库区（Pools 1-13 Upper Mississippi River System）与伊利诺伊河奥尔顿-马赛勒斯段（Alton-Marseilles, Illinois River）的航空影像数据，于2010年8月采用测绘级Applanix DSS 439型数字航空相机采集，影像分辨率分别为8英寸/像元与16英寸/像元，影像类型为彩色红外（CIR）。2011年8月，使用同款相机以16英寸/像元的分辨率，采集了密西西比河上游14号库区-南部开放河段（Pools 14-Open River South, Upper Mississippi River）以及伊利诺伊河德累斯顿-洛克波特段（Pools Dresden-Lockport, Illinois River）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、镶嵌与压缩处理，并通过UMESC互联网站点对外提供服务。本数据集的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年的LCU数据库由具备资质且经过专业培训的技术人员依据成文标准作业规程编制，或在其监督下完成，并经过严格的质量控制（QC）保障（NBS, 1995）。
