Abstract
The paper previews a computer-aided design system, PLANS, that is useful for developing timber harvest and road network plans on large-scale topographic maps. Earlier planning techniques are reviewed, and the advantages are explained of using advanced planning systems like PLANS. There is a brief summary of the input, output, and function of each program in the PLANS program set. The set presently includes programs for harvest unit design for a variety of cable logging systems, road locations, visual analyses, yarding costs, and slope attributes and a method for producing the elevation data files. Suggested ways to use PLANS to develop the harvest plans and to document and process harvesting alternatives are presented. Justifications are given for investments made in planning.
