The Weather Outline Contour Generator outlines areas of weather clutter at different intensity levels. Three experiments and several additional tests were performed to investigate two principal problem areas regarding the human factors aspects of the display of such data. The first problem concerned resolution--the level of detail or continuity required for reasonably complete and accurate representation of the shape and extent of the area of precipitation. This was tested by a recognition procedure. Twenty-three controllers correctly recognized, over 90 percent of the time, which of four actual weather patterns was represented by an outline made up of symbols spaced radially approximately 2 23 degrees apart. Doubling or quadrupling the resolution improved recognition slightly while increasing the certainty of recognition to a greater degree. Author
