    Description

    Emphasis on environmental and esthetic quality in timber harvesting has brought about increased use of complex boundaries of cutting units and a consequent need for a rapid and accurate method of determining the average yarding distance and area of these units. These values, needed for evaluation of road and landing locations in planning timber harvests, are easily and accurately determined by a desk-top computer and digitizer system programed in BASIC language. This paper presents two programs designed for that purpose.
