A DATA STRUCTURE FOR SPATIO-TEMPORAL INFORMATION MANAGEMENT
Yutaka Ohsawa, Weihong Guo, Mihoko Sakurai · 2002
This paper describes about spatio-temporal geographic information system, named STIMS(Spatio-Temporal Information Management System). STIMS handle temporal information assigned each geographic object and can execute several kinds of spatial operations on the world of specified time. The system adopts implicit topology data model to handle such temporal data. By this data model, the data structure for spatio-temporal geographic objects becomes very simple. This paper describes about the data structure and how to handle spatio-temporal data on the system. STIMS is now released as free software on the WEB. 1.
