Abstract:

This report describes three studies conducted to evaluate the effectiveness of map symbols for a computer-generated topographic display. The criteria for developing symbol effectiveness were transfer of training, potential confusion, and association value. A computer-generated topographic display, or CGTD, utilizes a cathode ray tube CRT, or other electronic display, to present map-like information. Conventional map symbols often are inapplicable with a CGTD because the matrix display elements, or pixels does not provide sufficient resolution for portraying small and detailed shapes. As a part of the research described in this report, design guidelines were developed for creating symbols that meet the limitations of a pixel matrix display. Sixty- nine topographic and tactical symbols were developed for the candidate symbol set. The evaluation of symbol effectiveness was conducted by means of three surveys completed by military personnel.
