Data modeling of moving objects with GPS/GIS in Web environment

摘要

Storing and processing the information about moving objects is crucial for a wide range of applications: traffic control, transportation industry/fleet management, digital battlefields, ecology/environment monitoring, mobile communication systems, etc. Consider a database that represents information about moving objects and their location. There is a critical set of capabilities that are needed by moving objects database applications and are lacking in existing DBMS's, they are: moving object's location modeling, linguistics issue, index and uncertainty/imprecision management. In this paper we propose our solutions of these questions and give a test-bed of them.
