Based On Webgis Jiangsu Province Price Information Network Research And Applications,

The building of land price information network is a important part in the item of the new round National Land and Resources Investigation City Land Price Investigation,as is for achieving the land price dynamic monitoring and the land price information sociality service system.Now some departments and districts have already construct their own web-site for land price information publication,but these web-sites have some shortcoming,such as lacking data resource,updating slowly,technology behind the times,incapable of managing complex space data.Along with the progress of computer network and GIS technic,It is necessary for requirement and possible for coming true to construct land price information network based on webgis.The author bring forward the construction scheme of land price information network in Jiangsu based on MapXtreme by making use of computer network,web programming and multimedia electronic map technology.In this paper, basing on expatiating the connotation of land price information network,the author analyse the background and significance of system construction,and discourse upon the way of land price network system design and development.at last, the author accomplish the system's investigation and research,software development,database building,and achieve anticipate purpose.In Section A,the author firstly expounds the meanings of Land Price,Land Market,Land Price Information Network. Secondly,the background and significance are put forward,and analyse system requirement and possibility .At last,the key technologies is introduced briefly.In Section B,the author treatises the course of the construction on the information system consisting of general target, design on function,data flow.design on software and hardware,data form and data structure,data dictionary,main function's achievement,interface design,security design,system integration etc.In Section C,the system is tested as an example of Nanjing and some harvest is obtained.In Section D,the author draw his conclusion and puts forward some advice about the information system.On the study of land price information network system,the author expatiates his own opinion,and lays stress on pratising.The results of his study are as followed:1.Strickly following national regulation and technology standard,based on computer network,web programming.webgis and multimedia electronic map technic,the author put forward the scheme for the construction of land price information network in Jiangsu.2.Accomplish main function's design and software development,and collect some data for system testing of land price information network system in Nanjing, which will be a successful example for the construction of land price information network in Jiangsu.
