Eye Noise and Map Design.
Merriam, Mylon
This paper describes the physiological "eye noise" effect of line contrast in maps and considers the effect of line contrast on the direct picture of terrain surface as produced by shaded relief. An attempt is made to describe map reading in its two major steps: 1) the enrichment of the brain image resulting from scanning the map sheet, and 2) the essential motion for the construction of map reading patterns. An experimental typographic map is proposed, with accompanying psychophysical scales, to study and control the eye noise effect. (Author/JLB)
