Metadata catalog of spatial data for the UMRS D'Erchia, F. 1993. Metadata catalog of spatial data for the Upper Mississippi River System Long Term Resource Monitoring Program. U.S. Fish and Wildlife Service, Environmental Management Technical Center, Onalaska, Wisconsin, November 1993. EMTC 93-P009. 62 pp. (NTIS #PB94-130002) ABSTRACT This metadata catalog was developed to provide potential users of Environmental Management Technical Center (EMTC) spatial data with information about available spatial data and how these data files were developed. However, since new data files are continually in progress, this catalog may not contain information about some of the more recently developed spatial data files. Catalog updates will be provided on a quarterly basis. The data listed in this manual primarily cover the Long Term Resource Monitoring Program study area. The study area is contained within the floodplain of the Upper Mississippi River System (UMRS), including the Illinois River and navigable tributaries between Minneapolis, Minnesota, and Cairo, Illinois. Most of the data files cover areas within specific pools (which delineate the impounded areas between lock and dams). However, the EMTC maintains additional data extending beyond the floodplain, such as transportation and county boundaries.
