Description: The Pacific Northwest Research Station (USDA Forest Service) is developing a knowledge-based information management system to provide decision support for watershed analysis. The system includes: (1) a GIS interface that allows users to navigate graphically to specific provinces and watersheds and display a variety of themes (vegetation, streams, roads, topography, etc.) and other area-specific information (relevant regulations, existence and location of analyses, plans, etc.); (2) an analysis component that helps identify major concerns and the hierarchies of associated ecosystem processes requiring analysis; (3) a report manager that displays the history, status, and details of analyses; (4) a project manager that assists with planning and monitoring of data acquisition; and (5) a hypermedia system that provides powerful navigation tools for accessing information in various policy and procedure documents. The analysis component contains dependency networks that link problem-solving knowledge about concerns, ecosystem processes, and data to specific landscape units. The goal-dependency approach provides a scientifically sound method for determining data requirements, as well as a basis for prioritizing, acquiring, and evaluating information for watershed analyses.
