Research Of Tourism Destination Information System Based On GIS

Tourism has developed rapidly in the past decades. With the development of information technology, the informationization of tourism industry has already become a kind of inevitable trend. In recent years, China's tourism industry has developed rapidly, but its informationization is still at an early stage of development. After joining in the WTO, the international tourist market will further expand. As a result of emphasizing on individualization by international tourists, a tourism information system that provides integrated multiple functions such as recommending, guiding, organizing and booking is strongly expected. Geographic Information System (GIS), as an important part of information technology (IT), has met the needs of tour products, which want to express their spatial characteristics ,because it has a set of special functions to inquire and analyze the spatial data. The combination of GIS and tourism will deepen the process of the information-based of tourism, change its present appearance and then promote the further and sustainable development of Chinese tourism.Today Internet is increasingly becoming the major source of gaining information and knowledge. In the aspect of communication and tourism, the use of Internet is especially important. The explosive growth in electronic Tourism Information System on Internet has fueled the quest for finding a new approach to supporting to access an extensive data on a distributed and heterogeneous TISs and geographic information sources, to achieve efficient visualization of tourism data, and to book tourism products. This quest has often led to applications based on Internet Geographic Information Systems. In the light of this, the thesis probes into the setting up of the tourism destination information system based on Internet GIS.This thesis firstly reviews and prospects the process of the tourism informationization at home and abroad, and chooses tourism destination information system as the combination of tourism industry and informationization. Secondly, some characteristics and implementation methods of using Internet GIS technology in tourism are analyzed and discussed with examples. When tourism information combined with the Internet GIS technology, it will provide a great opportunity and market potential for both sides. According to the analysis of the system's requirements we have got the data requirements and the elementary function requirements. Based on this, we set up a sample framework solution for the application. At last, two different algorithms are discussed to make out the best path.In this system, using spatial analytic function of WebGIS to carry out the subsidiary decision-making system. It also make good use of the function of statistical analysis to do some analysis in the scenic spot. The application provides a simple and convenient data manipulation. And it pays much attention to maintain the integrity and accuracy of data. The application also provides a convenient data output. You can use multimethods to query what you concern for. For example you can use vector information query, space data query or print special topic map what you need.Because tourism information concerns a lot of fields, the system still has many parts need to be consummated. But we believe that TIS based on WebGIS technology, which implements the function of Internet Publication, will be the trend of moderb TIS.
