Advanced Feature Symbolization for Three-Dimensional Views.

Abstract

This report documents initial research into the development of line-drawn symbols for point features in tactical terrain computer graphics. In this report, 21 significant point features for aircraft in tactical operations were selected for study. Symbols were designed for these 21 point features, with primary emphasis placed upon enhancing rapid user recognition, minimizing computer drawing time and computer storage requirements. Three candidate computer storage strategies, X-Y Absolute, Starburst and Run-Length-Starburst, were evaluated. The most efficient storage strategy for these symbols was the X-Y Absolute technique. The symbols were digitized, and software was developed to plot them in conjunction with existing three-dimensional terrain view software. (Author)
