    Description

    This user's guide provides instructions for using VIEWIT--a computerized technique for delineating the terrain visible from a single point or from multiple observer points, and for doing slope and aspect analyses. Results are in tabular or in overlay map form. VIEWIT can do individual view-area, slope, or aspect analyses or combined analyses, and can produce elevation profile charts between any two points in a study area. The guide explains how to prepare data, select available options, and interpret results. VIEWIT is designed to operate on a Univac 1108 computer with Exec-8 operation system. The VIEWIT system is accessible via remote terminals to the USDA Fort Collins Computer Center. For those not having access to this computer facility, the programs are available on request to: Director, Pacific Southwest Forest and Range Experiment Station, P. O. Box 245, Berkeley, California 94701, Attention, Computer Services Librarian. The programs will be copied on a magnetic tape to be supplied by the requestor.
