(NTIS #PB95-270807) ABSTRACT Resource managers are realizing the benefits of using geographic information systems to supply visual spactal data for use in making informed management decisions. This report details the ARC/INFO (ESRI, Redlands, CA) procedures used at the Environmental Management Technical Center in Onalaska, Wisconsin, to assist Upper Mississippi River National Wildlife and Fish Refuge mangers in the process of acquiring refuge land through a land exchange. Refuge managers required boundaries for both 430- and 500-acre parcels that included the most desirable land cover/use types. Hardcopy maps of the area showing the total acreage for each land cover/use type will be used during land exchange negotiations.
