This study treats of the evaluation and planning of townscape in historical cities. It statistically investigates the checking of height control zoning, by computer-aided design of 3-dimensional method in conservation surveying of townscape in Kyoto, Nara and Kamakura city. I have drawn the possibility of scenery space in a ratio of mountain skyline area, as part of a panoramic view, for height control zoning regarding what are suitable architectural heights in both commercial and residential areas. This study also comments upon the necessity of taking notice of visual analysis in townscape conservation by the height control zoning for land use in the future.
