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

文摘During the last decade, spatio-temporal databases have become increasingly important in many applications such as geographic information systems （GIS） and engineering information systems. 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.
