Design And Realization Of Map Inquiry System Based On LBS Platform

LBS platform has been the research hot spots now, as the social advancement, the fastening of people's life pace and the development of many communication technologies. According to the phenomenon that very few people research on map inquiry system on LBS comprehensively, a map inquiry system with comprehensive function is proposed by this paper. Users could access the system by mobile terminal and WEB; meanwhile, the system could locate mobile phone.At first, the frame of LBS platform and map inquiry system is designed; At second, several technology that been used in the system such as J2EE, WAP, locating technology and so on is investigated, MVC and J2EE which is ameliorated for the design are used, all of that enhances the stability of the system, at the same time, Oracle is adopted as the database of the system and Easy Loader which is from MapInfo Company is used to upload map files, which makes the database steady-going and easy to manage, besides, the design of Le/Ls and Li are studied, and the function of location is realized by the sequence of establishing connection, sending request and accepting response; Finally, the testing platform is constructed for the system, the results of every testing and analyses are exhibited, then the improving direction of the system is proposed.The map inquiry system has comprehensive function, good extensibility and reuse and it has flexible access manner, it also has good application value as to the progress of LBS platform. All of the works in this paper provide reference value for the development of LBS operation.
