| The geographic information system which is called GIS is one kind of specific space information system, it uses the modernized method to gather, the storage, the analysis, the control, the display and the simulation and the geography various spatial distribution related data space information system. Its core technology is the computer science and the technology, the based technology is the database, map visualization and the spatial analysis. The appearance of GIS for the tourism numerous and diverse data management, the multiple source achievement expression form and the space data analysis provided has been fastest, convenient, the accurate ways.The traveling geographic information system is one kind of decision support system which describes gathering, the storage, the processing, processing analysis and outputs the tour information. This information system also is a technical system that changes into the foundation by the tour information data, it uses the geography model analysis method, and provides many kinds of spaces and the dynamic tour information timely. This information system provides the policy-making control and provides the service to the society for the traveling control section. The traveling industry is a comprehensive industry, which includes several factors, such as travelling, food, lives, amusements and shopping. But the existing traveling profession can not adapt the demands of traveling industry's development. The traveling geographic information system technology (GIS) precisely resolves the contradiction which the traveling profession present stage meets and develops a bottleneck best technical platform, but based on the WEBGIS technology traveling public message service platform not only can the maximum limit satisfied tourist's need, moreover can the powerful improvement traveling investment conditions.The main service object of the Current traveling geographic information system (TGIS) is the tourist, and the main function is providing the traveling destination to the tourist the related information, but only a few parts faces the traveling control section and the traveling profession department, so it can not achieve three information sharing. This thesis'main contents revolves "based on the WebGIS provincial level traveling geographic information system" the design and the development. It takes Guangxi Province as an example, elaborated emphatically under the Internet conditions based on the WebGIS tour information system overall structure and the key development technology, which has studied the WebGIS related theory and the development mode. the thesis has studied traveling space data gathering, processing, has designed the traveling space database structure. Using the WebGIS formidable inquiry, the edition, the spatial analysis ability for the tourist, the profession user, the traveling control section has provided the rich tour information service function. Completes the function below specifically:1.Achieving the valid organization and controls of traveling space information.2.Achieving the organic classification and expresses of tour information.3.Achieving the inquiry and the information retrieval of the kinds of spatial entity localization.4.Achieving the spaces dynamic update and released of tour information.5.Providing the traveling resource appraisal analysis function and based on the GIS special map statistics function for the traveling control section.6.Based on C/S and the Smart client side union mode carries on the GIS space data and the attribute data update7.Has conducted the research to the WebGIS system safety control.The thesis could divide into four parts:1: The first part elaborated the present situation about traveling geographic information system development (TMIS). Through comparing TMIS and the traveling geographic information system, then draw out the establishment target and the significance of based on the WebGIS traveling geographic information system.2: The second part asymmetrically discussed the angle from the traveling market information to embark the nature to carry on the system demand analysis, elaborated developed WebGIS the essential key technology, and introduced based on SuperMap IS.Net method of exploitation.3: The third part is about the system structure and overall functional design. It introduces the national traveling resource classification standard, the evaluation criteria, and carries on the spatial data code, the space data mining and the spatial database structural design.4: The fourth part discusses the System backstage GIS data management function realization. The specific function divides into several repects which include implements faced to the ordinary tourist, the functions faced to traveling control section ,the traveling resource appraisal and the traveling capacity appraisal, the map downloading service, the system safeguarding and the map data update function which implements face to the profession unit which implements face the traveling scenic area scenic spot department which implements face the traveling control section.5:System backstage GIS data management function research and realization:Elaborated based on C/S, Smart client technology in GIS data renewal function realization.6:System safety control: Elaborated the WebGIS stand secure demand, utilizes Asp.The net identification authentication and the authorized mechanism protect the stand, carries on the connection string of character using DPAPI encryption several main contents7: The conclusion with recommended that, In view of the WebGIS development actuality, elaborated the work and the next WebGIS technology development direction which this system needs further to develop. |
