The Design And Implementation Of The Tourism Information Service System Of Digital Ji'nan City Based On GIS

With today's rapid development of GIS (Geographic Information System) and the tourism industry, the development of tourism and the improvement of the city's popularity are the important factors in the promotion of urban construction. The design and application of the Tourism Information Service System of Digital Jinan City based on GIS can not only promote the development of Jinan's tourism and improve the public image of Jinan as a tourismist city, but also greatly facilitate the travel of the tourismists, and provides the tourismists fast, intuitive and accurate information. On the other hand, the system also demonstrates the broad application prospects and powerful functions of GIS in the tourism industry. As an electronic guide, the system provides a simple information inquiry platform for users, which can provide intuitive and quick information services for the daily life, travel, food, shopping of users, as well as the location inquiry and propaganda of the enterprises and institutions.The design and implementation of the Tourism Information Service System of Digital Jinan City based on GIS in this paper is under the guidance of the RUP (Rational Unified Process), exerts object-oriented analysis and design techniques and uses UML (Unified Model Language) to establish business model, use case model, design model, and implementation model, adopts iterative methods to complete the entire process of analysis and design. In the process of analysis and design, Rational Rose, Power Designer, Visio and other softwares are used to complete the requirements analysis, architecture design, detailed design (classes design, data base design), coding and testing of the system. The system has good operation effect on single machine; it can realize the basic functions of GIS and meet the basic demands and technical requirements of the digital city tourism information service.Firstly, this paper, based on the discussion of the project background of the Tourism Information Service System of Digital Jinan City based on GIS and the problems in its development and design, makes a full understanding and analysis of the requirements of the system and obtains the needs of the users and the business processes. The paper also makes a full understanding from the aspects of the functional requirements and non-functional requirements of the system, and elaborates the system requirements in the form of flowchart and use case diagram.Secondly, on the basis of the analysis of the requirements, the paper considers the functional features of the tourism information service system, makes clear the system operational procedures of the system, determines the objective and principle of the design of the digital city tourism information system services, and brings the functional and technical framework of the system. In the technical architecture design, the design is carried on in accordance with the physical framework and the logic framework respectively; and the design process of the framework of the system is described in details.Thirdly, the paper carries on detailed design of the system and develops on two parts of system modeling and data base design. On basis of the description of the overall model structure of the information system, the overall structure of the system is designed and the system model is established; and the detailed design of every module and the design of the data base are respectively carried on. On the basis of detailed division of the interior functions of the system, a detailed design class diagram is given.Fourthly, the implementation and testing of code of the tourism information service system is completed. The implementation part comprises the overall implementation of the system and the coding of all the modules. The paper focuses on analyzing the implementation of the geographic information inquiry module and gives detailed description of the algorithm; then the paper introduces the circumstances of system test and analyzes the operation effect and deficiencies in details.Finally, the paper makes a simple introduction about the application circumstance of the Tourism Information Service System of Digital Jinan City based on GIS and summarizes the design and implementation of the system. The paper also indicates the aspects to be improved and the technical development direction of the next step, and proposes prospect and improvement suggestions of the Tourism Information Service System of Digital Jinan City Based on GIS.
