A study about database structure of spatial temporal geographic information system

摘要

In this paper, we have discussed the GIS that express the realistic world. Ouyr goal is to propose the database structure about 3dimensional spatial temporal GIS and to develop it, but in this report, we have especially paid attention to the way to deal with temporal information, and proposed the suitable database structure about 2-dimansional spatial temporal GIS. So we have developed one of the spatial temporal GIS, DiMSIS, that can handle the proposed database especially.
