In recent years, studies of geographic information systems (GIS) is made rapid progress. Practical use cases of GIS is found in some municipal offices. Then we developed indicators of land use mixture by using GIS data. Characteristics of land use has been evaluated by various methods. Most of them are calcurated by numerical data, such as floor areas by building use, areas by land use and the like. But we can't understand spatial distributions of land use mixture by these values. Then we propose indicators of land use mixture to evaluate spatial distributions by using GIS data related to polygons of plottages. These methods are applications of the JOIN concept which can evaluate spatial distributions of land use by using grid data. We also validated effectiveness of these indicators by applying to a study area in Kobe city.
