| With the rapid development of various fields in social life in the twenty-firstcentury,the service industry has become the focus of people’s needs in people’s dailylives.The rising navigation services are exactly playing a major role in people’stravelling.Although the navigation devices on the market are everywhere, it is preciselybecause of the popularity of navigation services required to bring a higher demand ofneeds and technology.People’s increased demand of accessing to information lead tohigher requirements for data storage and access.Now issues like slow data access tonavigation system,low efficiency of data updating and personalized user experience yet tobe rich enough need us go in-depth study.In order to solve the growing problems in navigation services,the system is d ividedinto five modules which are electronic map view,information inquiry,intelligentnavigation,3D environment virtual and gesture commands through a careful analysis ofsystem requirements according to the methods of software engineering.At first,i give theuse case diagrams by the analysis given by every user needs.After that i determine thearchitecture which uses MVC structure separate data,views and logic control through theoverall analysis about the system.Then i improve the system efficiency and data scalabilitythrough the use of data format known as NDS.And i analysis and desigh the details of thesystem upon every functional modules with the corresponding flowchart of functions.I use3D virtual technology in the system implementation to make the visual system moredimensional which provides users with a better service experience.The navigation system implemented in this article supports electronic mapinformation display,information inquiry,intelligent navigation,saving and settingpersonalized information and also the simulating for3D effects.When travelling,thesystem brings a positive meaning to be comprehensive,efficient and convenient in servicewhich improves efficiency by saving time and resource. |
