摘要
随着移动通信技术和地理信息技术的高速发展,二者的有机结合已成必然。该文重点研究了基于无线应用协议的移动地理信息系统的设计和实施,提出了一个WAP内容提供服务器的设计框架以及多用户并发控制和负载平衡分配、地理信息服务内容动态缓存、分布式异构数据源共享的解决方法。最后,给出了一个应用实例。
With the rapid development of Mobile Communication Technology and Geographical Information System Technology,it becomes a tendency to combine them organically.The paper focuses on making a research on design and implementation of mobile geographic information system based on wireless application protocol.It presents a basic frame of WAP content providing server and a solution to control of mutiple-user's simultaneous access and distribution of load balance,dynamic cache of geographical information service content ,share of distributed heterogeneous data source.Finally,it gives an application example.
