Based On Webgis, Jiangsu Province, The Land Market Network Research And Applications

Land market network of Jiangsu is a specialized network facing to society and grass roots, whose aim is realizing the function of issuance and sharing land market information, and satisfying the need of land trade-off and requirement of the public for land market information.With the rapid development of land market in Jiangsu province, land transaction become more and more active. It is time to establish a uniform land market information platform. At the same time, the increasing progress of computer and GIS technology make it possible to build land market network based on WebGIS technology. The system adopts B/S structure which based on ArcGIS and Oracle9i technology. With new computer technology, Internet, WebGIS, Multimedia and so on, land market information can be collected, handled, statistized, analyzed and published in order to service for land information issuance and the management of land market.This paper analyses the background and significance based on the brief introduction about its characters, then dwells on the demand and feasibility of the network, finally emphasizes the method of system design and development. The application of this network to the sample cities is successful.In section one, the author gives a brief introduction about land market network, and analyzes its background and meaning.In section two, the demand and feasibility analysis have been given for us about land market network reasonedly.In section three, the author provide us an illustration on the design and development including the total aim, function design, environment of hardware and software design, organization and structure of data, the major function implement, user interface design, system security design, system integration and so on.In section four, the author take some cities for examples, introduces the test and application of this system.In section five, some suggestion has been provided during the study and practice about this system.In the period of study, the author always obeys the principle that theory keeps up with practice, and dwells on her own opinions. In this paper, the major achievements are following:1.Keeping with trade regulations and technology criterion, combining with the marketdemand, adopting computer technology, Web programming, WebGIS, electronic map, multimedia technology and so on. provide the building model of the Jiangsu land market network.2.Complish the design and development on major functions of the sample cities, and build their data-base, consequently build up a successful example for the land market network building and application.
