摘　　要：在分析目前地图服务存在问题的基础上,将网格技术应用到移动空间信息服务领域,研究了基于网格的位置服务原理和特点。针对地图服务存在的问题,提出了基于网格的地图服务,并通过与J2ME技术的结合实现了一个Java手机地图服务系统,可以改善地图服务的性能,提高位置服务的效率。In order to resolve the problems of map services, grid technology is imported into the domain of geospatial information services in the dissertation. This paper studied the principle and character of location based services based on grid. The method of map service encapsulation into Grid service is put forward, a map service system on Java mobile phone is implemented based on J2ME technology and grid map service technology. It could improve the performance of map services and the efficiency of location based services.
