Abstract
This paper aims to reveal a usefulness of the GIS database with integrated data managed by a local administrator by grasping information of unused houses and empty lots in the H, massive residence area in M city. The H has 564 empty lots and 131 unused houses. An average total floor space of unoccupied houses is 113m2. It is under that of occupied houses (129m2). An average area of empty lots is 428m2. It is over an average area of lots on which occupied houses are built (353m2).
By the database and the research on 2001.1-2 about desire for remove, it is recognized that 22% of residents of own houses and 83% of residents of rented houses wants to remove on several levels in the H and, from a result of easy calculations, 67 lots have high possibility to be removed in the H and H5 area has relatively high rate of lots will be removed.
From a result of analysis about changes of lots and houses in H7 area, it is recognized that half of unoccupied houses aren't used over 2 years, most empty lots aren't used effectively long times and some empty lots are neighboring lots.
