This paper discusses the design and implementation of a geocomputing platform for the development of location-based services （LBS） focusing on mobile mapping. During the analysis, design, and implementation of the geocomputing platform, an effective method is proposed for the real-time processing of geographic information acquired by a camera attached to a personal digital assistant （PDA）. This method combines location information given by the global position system （GPS） with man＇s ability to recognize the location of objects and their geographical relationship to improve object mapping.展开更多
LBS服务是跨行业的系统集成应用,具有十分光明的商业应用前景,但其对应的许多系统都缺乏一个稳定的和可扩展的体系结构。因此,对LBS服务系统选择稳定的体系结构和可扩展的平台显得非常必要。本文设计一个可扩展的位置信息服务平台LSP(Lo...LBS服务是跨行业的系统集成应用,具有十分光明的商业应用前景,但其对应的许多系统都缺乏一个稳定的和可扩展的体系结构。因此,对LBS服务系统选择稳定的体系结构和可扩展的平台显得非常必要。本文设计一个可扩展的位置信息服务平台LSP(Location Service Platform)系统,提供可扩展的平台接口,可以高效地开发出各种LBS应用,还可以逐步向以应用为导向的LBS综合服务平台完善。展开更多
