摘 要:基于位置服务是地理信息应用与服务领域快速发展的重要技术。针对基于位置服务技术日益广泛的应用和未来发展的前景,该文介绍了基于位置服务的概念、体系结构和服务模式。详细剖析了实现基于位置服务的关键技术(包括移动定位技术和地理空间信息技术)及当前进展;分析了其在实际应用中存在的问题,包括定位精度无法保证,动态位置信息的采集工作量大且信息整合参差不齐,地图数据的快速浏览对移动终端的处理能力和存储能力要求较高,及用户个性化的隐私需求无法满足等,并指出了其研究热点和未来的发展趋势。Location-based service (LBS)is an important technology in the field of geographic informa- tion application and service developed rapidly. For the increasingly wide applications and future develop- ment prospects of the LBS technology, the concept and architecture and service model of LBS were intro- duced in this paper. The key technologies consisted of mobile positioning technology and geospatial infor- mation technology and the current progress of LBS were analyzed in detail. Furthermore, the topics of LBS, such as positioning accuracy not guaranteed in the practical application, the heavy workload in the dynamic location information acquisition and being uneven in information integration, higher processing and storage capacity of mobile terminal in quick browse of map data, and being unable to meet the privacy demand of individual users were analyzed. Finally, the future trends and research focus of LBS were point- ed out.
