The Research And Application Of The JiangSu Constructive Land All Process Tracking And Managing System Based On WebGIS

With the development of economy, as an important production resource, land play an important part in Macroeconomic regulation and control. In order to understanding and grasping the supply and use of land timely and comprehensively, tracking the progress of every constructive land, promoting the intensively use of land, improving the use rate of land, the construction land all process tacking and managing system must be put into effect.This paper researches the theory of the managing of constructive land, introduce the concept of the All Process Tacking and Managing and it's system safeguards It concludes some problems in the traditional tacking and managing of constructive land, discusses the development status and problems of the tacking and managing of constructive land in recent years in China. Then, this paper analyses primarily the demands in informationization and technology of the tacking and managing of constructive land.The paper constructs the system model of the All Process Tacking and Managing of constructive land . And then, the paper deeply research the model,, the composing of data, the data workflow, the design of network; imports the technology of WebGIS, and designs WebGIS application model of three layers.Finally, based on the building about e-government of Ministry of Land and Resources in Jiangsu Province, taking the service of JiangSu constructive land all process tracking and managing system as an example, with the help of the map server of ArcIMS and ArcSDE spatial engine, building a formidable system of JiangSu Construction Land All Process Tacking and Managing.The paper's primary content as follows:1. Analyzing the necessity of the constructive land all process tracking and managing system, Discussing the demand in informationization and technologies of the all process tracking and managing of constructive land.2. Analyzing the system mode of the all process tracking and managing of constructive land Using ArcIMS, ArcSDE and the technology of Java, based on the WebGIS application model in the three layers, the paper designs the information system of the all process tracking and managing constructive land of province-level, city-level and country-level, and try to carry out the informationization of the all process tracking and managing of constructive land in network, the integrative management of paper and image, cooperation among multi departments and so on.3. Based on point 1 and point 2, the paper designs the system——JiangSu constructive landall process tracking and managing System. The system carries out the cooperated all process tracking and managing constructive land of province-level,city-level and country-level by network..
