Abstract:

Periodic land cover maps of the Upper Mississippi River System UMRS floodplain are required by resource managers to understand and monitor the system. Typically, land cover maps for the UMRS are produced through interpretation of aerial photography and stored as geographic information system ARCINFO coverages. True-color and color- infrared photos scale 115,000 of the entire UMRS were collected in 1989 as part of the Long Term Resource Monitoring Program LTRMP. Nearly the entire UMRS floodplain was interpreted from these photos. The exceptions were Pools 1-3, most of the Open River the UMRS from Lock Dam 26 located near Alton, Illinois downstream to its confluence with the Ohio River near Cairo, Illinois, and about half of the Illinois River. Sections of the UMRS have been re-photographed and interpreted in subsequent years, but the same gaps in coverage remain. In an effort to fill these gaps, land cover data for the Open River were acquired by the U. S. Army Corps of Engineers USACE to incorporate into their River Engineering and Environmental Geospatial Information System REEGIS, Figure. Recently, a conversion routine was developed by Environmental Management Technical Center staff to translate REEGIS data from Intergraph Design files to ARCINFO coverages.
