Environment for Spatial Information Sharing

This paper concerns Web-based spatial and local information sharing for digital cities. There are various kinds of spatial information such as geographical maps, illustrated maps, railroad maps and so on around us. Our system provides an environment in which the general users can submit such contents on their favorite map and in which they can view contents submitted from more than two providers on their favorite map. In our system, all spatial information submitted by citizens is linked in special index tables. This paper also shows digital city applications of the presented environments.

An Information Delivery Method Driven by Event Matching for Information and Control Systems

In recent years, in the industry, real-time decision making integrating plant field and business systems information has become indispensable. In addition, with the arrival of the ubiquitous information society, the use of sensors in the field and information utilized for business are increasing. In this environment, handling field information in real time and connecting it with business is a crucial challenge. With condition-based management, the facilities are monitored and are kept in good condition depending on their state rather than according to a prescribed schedule. However, in the event of a facilities error, demand for access to the same data centers increases, degrading response performance. A method is described for delivering information data to operating applications as triggered by a control event. In the event of a facilities error, access to information data is integrated, and the information data is duplicated and delivered to operating applications. Then, concentrated demand for access to information data can be avoided, and the response performance of operating applications can be ensured. Since the method has not been tested, it is now necessary to perform a feasibility study including performance verification
