Prototype of moving object visualization engine

Abstract

This paper proposes a prototype of moving object visualization engine. This engine is expected to display moving object, such as moving point, moving line, and moving region. One of an existing tool that has implemented this feature is Java GUI of SECONDO. But, it is not easy to integrate the GUI module with any particular web-based information system that has to visualize moving object. Using Google Maps API, it is possible to build our own engine that can be easily integrated with our web-based information system, or any particular web-based information system. To build this engine, we adopt data model and data structure used in SECONDO. This data structure includes definition of moving object data type such as, mpoint (moving point), mline (moving line), and mregion (moving region). These types are function of time of corresponding spatial data types: point, line, and region. Further, this engine will be validated by using it in a simple web application, Disaster Information Management System, which will display the moving area of any types of disaster, such as flooding, tornado, tsunami, etc.
