Summary
The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) has created high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS) from 1:15,000-scale color infrared aerial photos collected in 1989. The data are available in two formats. The first used a detailed genus-level classification scheme and was used to classify Mississippi River Navigation Pools 4 through 26, the Open River between Grand Tower and River Mile 32, and the Peoria navigation Pool on the Illinois River. The second classification scheme was developed in 1998 in response to a scientific and programmatic review of the center's mapping projects. This classification scheme identifies plant communities and associations. [...]
Summary
The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) has created high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS) from 1:15,000-scale color infrared aerial photos collected in 1989.

The first used a detailed genus-level classification scheme and was used to classify Mississippi River Navigation Pools 4 through 26, the Open River between Grand Tower and River Mile 32, and the Peoria navigation Pool on the Illinois River. The second classification scheme was developed in 1998 in response to a scientific and programmatic review of the center's mapping projects. This classification scheme identifies plant communities and associations. This second classification scheme was used to interpret data for Mississippi River Pools 1 through 3, the Open River between Lock and Dam 26 and Grand Tower, and the Alton, Starved Rock, Marseilles, Brandon, Dresden, and Lockport navigation pools on the Illinois River. At the time this metadata document was prepared data classified underneath the first classification scheme were being cross-walked to the new scheme. This metadata document has been prepared to document the second classification scheme.

Purpose
The Upper Midwest Environmental Sciences Center administers the US Army Corps of Engineers Long Term Resource Monitoring Program, an element of the Upper Mississippi River Restoration- Environmental Management Program (LTRMP), authorized under the Water Resources Development Act of 1986 (Public Law 99-662). The mission of the LTRMP is to provide decision makers with information to maintain the Upper Mississippi River System (UMRS) as a viable large river ecosystem given its multiple-use character. The long-term goals of the Program are to understand the system, determine resource trends and impacts, develop management alternatives, manage information, and develop useful products. The creation and distribution of high-resolution land cover/use data for the UMRS aids the Center in meeting these goals.
