Land price maps of Tokyo Metropolitan Area

The spatial distribution of land price is indicative of the urban structure of a region. However, since most information on land price is in the form of point data and not area data, a certain process must be established for the creation of a land price map. The authors have already developed a computer-aided system that enables the creation of precise land price maps on the basis of residential land price data for metropolitan areas in Japan at low cost but with precision. In this paper, the system is applied to Tokyo metropolitan area and creates several land price maps using the officially assessed land prices provided by the Japanese government and data from the land price surveys conducted by prefectural governments.
