For the Army aviator, Night Vision Goggle (NVG) flight in the tactical rotary-wing profile is a very demanding, task saturated environment. Map navigation is just one of the many tasks that must be accomplished during flight. The dim, monochromatic lighting required for NVG flight alters map colors, decreases image detail and map feature contrast, often making terrain feature recognition more difficult. A cartographic analysis and resulting map enhancement is needed to improve feature recognition, allowing easier navigation and safer flight. In this study, it was found that when applying a non-gray scale (magenta based) relief shading to a 1:50,000 scale military topographic line map, the surveyed aviators determined this shading improved or significantly improved their ability to visualize the terrain. It was also found that a medium level of shading (75% DEM opacity) was preferred.
