在本文中，我们讨论了通过阪神淡路大地震灾害所获得的灾害及恢复支援活动经验而开发的灾害应对支援系统。在灾害时期使用的信息系统必须具备以下三个特征：1）正常时期和紧急时期之间的连续性；2）分散的独立性；3）时空信息的整合。为了实现这些特征，我们开发了DiMSIS，作为一个时空信息系统的原型。DiMSIS具有一种数据结构，其中对象之间没有明确的拓扑关系，并且拓扑关系针对每个查询实时进行概括。这个概念对于构建一个分散的系统具有极大的优势。它能够轻松地整合时空信息。最后，我们给出了在正常时期和紧急时期信息处理的有效实例，以证明所提出系统的有效性。
In this paper, we discuss the disaster response support system developed through experience with disaster and recovery support activities obtained as a result of the Great Hanshin-Awaji Earthquake Disaster. The information systems to be used in times of disaster must have the following three features: 1) continuity between normal times and times of emergency, 2) decentralized independence, and 3) integration of spatial and temporal information. To actualize these features, we have developed DiMSIS, as a prototype of a spatial temporal information system. The DiMSIS has a data structure without explicit topological relation among objects and the topological relation is generalized for each query in real time. This concept is far superior for constructing a decentralized system. It can easily integrate spatial and temporal information. Finally, we present effective examples of information processing in normal times and times of emergency to demonstrate the validity of the proposed system.
