Abstract
WRIS (Wildland Resource Information System) is a computer system for processing, storing, retrieving, updating, and displaying geographic data. The polygon, representing a land area boundary, forms the building block of WRIS. Polygons form a map. Maps are digitized manually or by automatic scanning. Computer programs can extract and produce polygon maps and can overlay, plot, and store them, as well as aggregate acreages and print summaries. WRIS is functionally oriented toward timber management, but can be used for other types of resource activites.
