UMRS LTRMP 2010/11 LCU Mapping -- Illinois River Alton Pool

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).

本数据集涵盖密西西比河上游水系1-13号池与伊利诺伊河Alton-Marseilles池段的航空影像：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/像素的分辨率采集彩色红外（CIR）航空影像。2011年8月，使用同款相机，以16英寸/像素的分辨率采集了密西西比河上游14号池-南部开放河段及伊利诺伊河Dresden-Lockport池段的彩色红外航空影像。所有彩色红外航空影像均完成正射校正、镶嵌拼接与压缩处理，并通过UMESC互联网站点对外提供访问服务。本数据集采用31类LTRMP植被分类体系对彩色红外航空影像开展解译与自动化处理。2010/2011年度LCU数据库由合格且经专业培训的人员依据成文标准作业规程编制，并经过严格的质量控制（QC）保障流程（NBS，1995）。
