Personal Travel Assistant Based On Mobile Gis Design And Realization

Currently, there are in increasing numbers people who are keening on self-help tourism. However, in the process of self-help tourism, there will be many difficult: for example, tourists can not understand the knowledge of attraction, even in the face of danger he was unable to help himself or to be saved, which reduce the quality of tourism. At present, the navigation products of market can not completely meet the needs of tourists, so visitors make a higher demand to the self-help tourism. Tourists eager to hold a self-service travel navigation product, whose functions can introduce accurate information, vivid images, real-time online through human-computer interaction. It demonstrates a valuable tourism information to tourists. The purpose of this paper is to develop appropriate self-help tourism navigation system, so as to solve self-service travel difficulties and real-time data update.Therefore, not only does the research significance improve the quality and efficiency of tourism, but also promotes economic and social benefits, promoting the tourism industry sustained and stable development.In this paper, using systems engineering theory and methods, by using object-oriented technology, the paper develops tourism navigation system based on mobile GIS. It mainly includs the following in this research projects:(1) GPS + GIS + CDMA technology applied research in the tourism industryThe tourism navigation systems have been fully researched and investigated. GPS, GIS, CDMA / GPRS / GSM wireless communication network technology are analyzed and are not fully integrated together. It can not give tourists and real-time mobile GIS and the Internet interactive experience. In this paper, it puts forward a design that GPS, GIS, CDMA are integrated.(2) System DesignThis system is strictly designed in accordance with standard of software design. First, the system is a macro-design: software architecture, hardware system architecture; Second, each functional module is detailed designed: the system functional design. According to the macro-planning and design out the need to implement the software features identified by the software functions needed to support the hardware modules in order to design the hardware system architecture.(3) part of the software functions to achieveI use eSuperMap which provide functions implemented some of the software features, such as browsing maps, navigation, path selection of the best, query modules.By researching embedded hardware, WIN CE technology, GPS technology, GIS technology, the subject has completed some functions of tourism navigation system based on mobile GIS. After it is runned and tested in the experiment, I give a good test results. The functions of the system are to be fully realized, GIS can be closely linked to the Internet, then provide personalized service to our life and tourism, and bring huge benefits. To achieve the true sense of self-help travel anytime, anywhere, no time or manpower constraints. Because tourism information concerns wide fields, there are many deficiencies and shortages that must be further improved and perfected.
