The Design And Implementation Of Mobile GIS Application System

Mobile Internet of Things technology in the range of the network, can realize the interconnection and interworking between man and man, things and things, the people and things.Demand that it is destined to Mobile Internet of Things cannot leave a mobile space positioning and spatial location Information analysis visualization of Mobile Geographic Information System(Mobile Geographic Information System, abbreviated Mobile GIS).Mobile GIS is an important part of Mobile Internet system.In this dissertation, using the baidu map iOS SDK carries out the research and realization of Mobile GIS application system based on the iOS device.The dissertation introduces the definition and characteristics of Mobile GIS and main composition elements, summes up the current market popular Mobile operating system, Mobile GIS, and the mainstream of development mode, etc.,describes the iOS application development requires integrated development environment and it’s set up and configuration.The dissertation focuses on analyzing the key technologies of the development of Mobile GIS based on the baidu map iOS SDK, such as Mobile space orientation, baidu map and campus space position data’spreparation, publishing and load, the server database management and the data transmission between the client and the server database, etc.In this dissertation, based on the research of key technology of Mobile GIS, Mobile GIS application system that taking Hangzhou Dianzi University for example was implemented.This system implements a variety Of functions, including the campus POI(Point Of Interest) information query, the campus information services based on the location, the classification Of the campus POI elements display control, custom campus internal pedestrian route planning between a hot spot amd ohters, campus 3D liveaction picture viewer, custom map measuring distance function, mobile positioning and query campus POI around the positioning location by automatically opening positioning function, etc.This dissertation also has carried on the preliminary exploration of campus indoor localization of large buildings based on the location fingerprint identification technology, discusses and analyzes the related research methods and results.Through the above exploration and research for Mobile GIS application system development provides a reliable research method and development process, also lays a solid foundation for further research.
