Research on mobile GIS based on LBS

Abstract

Mobile computing system based on personal digital assistant (PDA) products has been used widely, and location-based service (LBS) is one of the most promising application directions of GIS. It is important to integrate the mobile computing technology and GIS technology to meet the need of LBS. The purpose of the paper is to propose a solution of mobile GIS based on LBS by studying the difference between the personal digital assistant (PDA) and traditional desktop computer. The totally new system architecture of the system and detailed function of each component is presented, and on the base of this, the method of spatial data management, spatial data compression, spatial data index, and the visualization of digital maps are also proposed. Base on our strategy, a GPS device is used to get the location information to prove the validity of our strategy. Experimental results demonstrate our strategy can meet the actual need of enjoying LBS anytime and anywhere.
