Abstract

With the rapid development of the computer hardware, software and the network technology, a great deal of multimedia contents including graphics and images can be displayed on the mobile device like mobile phone, PDA and vehicle equipped terminals. In this paper, we put forward the concepts of dynamic data file and automatic update engine, which are both applied in our mobile GIS architecture. The former are used to supply information for local query, the latter updates the former when necessary. By this mechanism, we reduce the network transfer frequency to minimum, raise the efficiency and fully utilize the computing capacity of the mobile device and application server in the mean time.
