    Description

    This paper describes four computer programs for the logging engineer's use in planning log harvesting by skyline systems. One program prepares terrain profile plots from maps mounted on a digitizer; the other programs prepare load-carrying capability and other information for single and multispan standing skylines and single span running skylines. In general, the three skyline programs prepare load paths, forces, and cable tension information from inputs of equipment specifications and anchoring geometry. Listings and explanations for all programs are included.
