摘要

This study aims to track the newly appearance, the disappearance, and the change of almost all of the tenants in the Tokyo Roppongi area in the period of 1995 to 2005 in about five year blocks. Quantitative methodology for this study is to use digital town map data (ZENRIN Zmap) using GIS or other programs. Those data used in this study include name, location, and floor information etc. for each individual tenant. We are able to know what kinds of businesses appear or disappear concentrically for some area, or whether the floor occupied by those tenants influences the tendency of the movement of them, according to these time series analyses. Features for this study are to provide detailed spatial information and database for three-dimensional based usage for urban area using existing database merchandised for other purposes. In this study, dataset for each change of commercial tenants are analyzed and detected. Commercial buildings that have different pattern of tenants' change are expressed on maps in Tokyo Roppongi area.
