The Key Technologies and Related Applications of the 3G-based Mobile GIS System

Abstract：With the development of the third-generation (3G) mobile communication technology, the traditional Geographic Information System (GIS) is quickly evolving into the mobile GIS system, which consequently makes the applications of the GIS system to more new areas.The paper firstly introduces the infrastructure for the emerged 3G-based mobile GIS system, and then describes principles, design procedure and implementation of some key technologies involved in the 3G-based mobile GIS system, which including the WAP protocol, the evaluation of different positioning methods etc.Finally takes Location-Based Service (LBS) as a practical example to show the latest development of the 3G-based mobile GIS system.
