Abstract
UTOOLS is a collection of programs designed to integrate various spatial data in a way that allows versatile spatial analysis and visualization. The programs were designed for watershed-scale assessments in which a wide array of resource data must be integrated, analyzed, and interpreted. UTOOLS software combines raster, attribute, and vector data into "spatial databases" in which each record represents a square pixel of fixed area, and each field in the database represents a map layer, theme, or attribute. UTOOLS includes several common GIS functions, such as procedures for calculating buffers, slope, aspect, patch size, convexity, and measures of topographic diversity. The UVIEW program provides rapid two- and three-dimensional images of digital elevation models, attribute data, and vegetation patterns at watershed scales. UTOOLS programs fulfill the routine analytical needs of resource professionals at low cost and without the expense and training required by many other spatial analysis and visualization systems.
