Research On Key Technology Of Business-oriented Information Services Web-gis Platform

With the promoting of global IT process, information technology has come to pervade every aspect of social economy. In such a case, enterprises as the main part in market economy should do what they can do to achieve their own informatization. Only in this way can they boost their competitiveness. Furthermore, WEB-GIS as an implementation tool to accelerate the enterprises informatization is rapid development, and the application of WEB-GIS in enterprises informatization has become a new direction for WEB-GIS.Based on the development of the business-oriented information services WEB-GIS platform, the thesis formulates the theories and technologies of WEB-GIS, researches several commercialized WEB-GIS platforms, and tentatively achieves the development of business-oriented WEB-GIS. Moreover, the thesis also pays more attention on the research of key technologies for WEB-GIS and displays the details that show as follow:1) Research on the of characteristic business-oriented information services WEB-GIS platform. On the basis of analyzing the characteristics of WEB-GIS and enterprises informatization, it reveals the difference between business-oriented WEB-GIS and other WEB-GIS. Then according to the difference, a suitable framework has designed for business-oriented WEB-GIS.2) Research on the problems of WEB-GIS development. After introducing the development status of WEB-GIS, the thesis compares different WEB-GIS platforms, then sums up the problems which must be solved in the development of WEB-GIS, such as how to balance the amount of data and speed in the network transmission, how to ensure interactivity and scalability of WEB-GIS and how to realize the interoperable task among several WEB-GIS platforms.3) Research on the key technologies of business-oriented information services WEB-GIS platform. The thesis researches key technologies in the development of business-oriented information services WEB-GIS platform, which include the transmission of space data by TileMap, the visualization of statistical diagram and the customization of the system database.By the study of these problems, the development of after-sale services WEB-GIS for Shanxi Fast Gear Co., Ltd., which is an example of business-oriented information services, is completed. It serves as an important step towards the application of WEB-GIS in enterprises informatization. Finally, it also reveals the new vistas of research for WEB-GIS.
