The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) in conjunction with the Upper Mississippi River Restoration Program's Long Term Resource Monitoring (LTRM) element has created high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS) from 1:24,000-scale color infrared aerial photos collected in 2000. The photos were interpreted using a 1-hectare 10% minimum vegetation cover to delineate land cover/land use, percent vegetation cover, tree height, and hydrology regime. The geographic extent of the UMRS is the Mississippi River from Cairo, IL to Minneapolis, MN and the Illinois River from its confluence with the Mississippi near Grafton, IL to Lake Michigan. <\/span><\/p>
