Fundamental Study on Measuring Color of Landscape by Photoelectric Colorimeter

Abstract

Landscape assesument used color to predict visual impact of activities, but they had no moderately precise means for meauring color. The purpose of this paper was to examine usefull of photoelectric colorimeter. The color of landscape were measured by color readings and photoelectric colorimeter. We commpared a sort of two data. As a result of investigating of color, measuring color by photoelectric colorimeter found major four problems as for a change of weather, an incidence angle of the sun's rays, a shadow and a length of survey. This measuring system was usefull under the control of four factor. However data in this paper were insufficient to develop marker sets of colors for landscape. From now on, this measuring system is necessary by this collection of many landscape data. Advancing of this study applied to landscape assessment and landscape management of natural park.
