This research is intended to develop techniques to manage spatial information (e.g. terrain, building locations, legal regulations, plant habitats) and temporal information (e.g. water level, rainfall, traffic volume) jointly.
We investigated how spatio-temporal information is used in public sectors which have introduced GIS. Products of GIS that are able to use spatio-temporal information (spatio-temporal information system) were also investigated. These investigations showed that spatio-temporal information should be managed, but is not managed because there are not enough spatio-temporal information system products and users do not know how to implement spatio-temporal information system for practical use.
Characteristics of temporal information were analyzed and basic functions were designed to create a spatio-temporal information system. Based on the design, three prototype systems for specific applications were developed and demonstrated advantages for managing spatio-temporal information.
