This paper aims to build a spatiotemporal GIS database about boundaries of municipalities. The municipality is most popular spatial unit used for statistical data in Japan. However, because the boundaries of the municipalities often change, it is difficult to compare statistical data in two time points. This database allows us to obtain the boundary GIS data of municipalities at any given time point after 1970 and the correspondence table of municipalities between two time points through the web-based interface of this database. This database, named “Municipality Map Maker for Web (MMM4W)”, facilitates the GIS analysis using the statistical data by municipalities with a temporal dimension.
