Illinois River Restoration Needs Assessment GIS: RNA-GIS (User Manual)
Abstract
The Illinois River RNA-GIS application and geospatial database were developed as a tool to support the Illinois River Ecosystem Restoration Feasibility Study Restoration Needs Assessment (RNA). Its purpose is to assist in the evaluation of historic, existing (primarily), predicted future, and desired future conditions of the Illinois River Watershed by providing an extensive geospatial database and customized GIS analytical capabilities. The study area and extent of the associated geospatial database includes the mainstream Illinois River, its tributaries, and watershed. The application is structured to provide access to GIS themes at three different scales: (1) the Illinois River Watershed, (2) the major tributary watersheds USGS Hydrologic Unit Code-8 (HUC-8), and (3) the subwatersheds USGS Hydrologic Unit Code-12 (HUC-12). This method of organizing the application and geospatial database supports data browsing, data queries, and summaries at all scales in support of large-scale planning and smaller-scale, site-specific project formulation. The Illinois River RNA-GIS application was created using Environmental Systems Research Institute (ESRI) ArcGIS8.X software and Microsoft s Visual Basic for Applications (VBA), which is included with ArcGIS8.X products.
