The ARC/INFO system is a powerful GIS that is widely used by natural resource organizations. FRAGSTATS is an extensively used program that derives a comprehensive set of useful landscape metrics. The Forest Vegetation Simulator (FVS) is a forest growth and yield model used throughout the U.S. Forest Service. Fully integrated links between ARC/INFO and the FVS and FRAGSTATS programs through user-friendly graphical menus consist of scroll lists, toggles, and buttons to facilitate program specifications and automatically generate appropriate tables, charts and maps for enhanced interpretation of the results. The FRAGSTATS*ARC and FVS*ARC programs control the selection of maps, access of ARC/INFO data, selection of program indices, program execution, storage of results in data base tables linked to ARC/INFO maps, and display of results in a variety of tables, charts, and map displays. The differences in spatial character of the two applications resulted in different approaches to accessing and processing the data used in the seamless link between the forest management programs and the GIS.
