Development Of Multimedia Tourist Information System Based On Integration Of VB And MapObjects

As the popularization and application of the multimedia technique and GIS, every city tourist responsible institution and enterprise begins to pay attention to development and construction of the information system of the travel, national tourism administration regards tourism information system of touch-sensitive screen as city outstanding one of tourist to grade the index even. Intuitionistic, vivid and excellent picture with text desired, tourism information system differents from a general information system. It requires multimedia data of tourist element is combined with its geographic space figure and related properties and tourists can search and inquire about between three. Two kinds of basic platforms, GIS and multimedia manufacturing system, have certain defects. Popular multimedia making software, such as Authorware, Director and Founder Author Tool, etc., are mutual, flexible and expressive, but they cannot effectively manage space figure and lack space analyze and count function;Integrated software on the basis of GIS, for example MapInfo and Arcview, have the powerful ability of space analyze, but lack media's information such as the sound, video, cartoon. They can only express and transmit space information with the aid of the text, figure and table, the way is single, which reduces the function of GIS dealing with and transmitting the space information. This thesis expounds the application of GIS combined with multimedia technology to the regional tourism information system. This way helps to increase efficiency of tourism and expand new markets. Multimedia GIS has already become the hotspot of GIS.Lack of multimedia GIS tools at present, multimedia GIS can be made by two ways: one is from the development of the ground floor;another uses existing multimedia making software or map platform to expand to realize the system. As the attempt of the last way, this thesis describes the process to program multimedia travel information system and some functions based on MapObjects control in VB.The multimedia tourism information system is a concrete application of the multimedia GIS. And there are five parts in this article:Chapter one: preface. The author introduces the meaning of study, the research current situation, main research contents and technique means of study.Chapter two: the key technology of system. The technologies relating to this paper are digitized technology, interface between VB and database, multimedia program, the connection between multimedia data and space figure. And the author puts forward the concrete application scheme.Chapter three: system design. In this part overall frame and functions of the system are designed and discussed. The author introduces the principles of the system design, the design of database, and user' s interface design.Chapter four: system application. Taking Baoji city as an example, this part specifically expounds the process of development and application.Chapter five: summarize. The author states the productions, the shortages, and the direction of this paper.Basing on the consulting tourism information system that other provinces and cities have set up, this dissertation mainly study multimedia inquire, click and broadcast, and attempt to try and break through in the following:1) Try boldly in multimedia GIS tools, and attempt to set up the multimedia tourism information system by my own programming.2) Adopt the multimedia database based on file, regard attribute database as the core, and set up the connection of space, attribute and multimedia data through the related field ID, which can realize the interactive inquiry from space data to attribute data (include multimedia message).3) Many kinds of inquiry ways are provided for the tourists, every kind of information inquiry result can give you many kinds of choices, which can realize click and broadcast of multimedia information and almost meet visitor' s inquiry deirand.4) The system adopts the module design, all movements are integratedin the button. As long as clicking the corresponding order button, the users can carry out a certain movement. The interface is friendly, any user who can understand the basic computer knowledge can operate this system.5) In the course of the development, the system widely uses VB multimedia program, which can support many kinds of media display, such as picture browsing, text dealing with, audio and video broadcasting, flash cartoon showing and the background music broadcasting continuously.
