Gis Management Information System Development And Key Technology Research

A big project of geographic information system is not only along-termand arduous construction project, but work amount areenormous, completion time is urgent, implementation of the technologywhich involres is very complex, so implement of the project proposed avery high request. How to realize the effective management, publishingand sharing of project information, which are of vital significance toenhance the renewal project operation efficiently and reduce the risk ofproject management. Simultaneously, this project involved a mass ofuncommon Chinese characters, total 2811, which are replaced by theserial number at present, and brought huge difficulty for the cross regioncooperation.Along with the popularization of Internet and the fastdevelopment of Web technology, it is an important trend of GISdeveloping that GIS is based on Internet. Under this background, thispaper presents the thought of establishing the enterprise level centralizedmanagement GIS project information publishing system based on WebGIS.This article first penetrates with studies of system structure,realization technology and relevance knowledge of Web GIS, afteranalyzing several major domestic and foreign Web GIS platform,proposes the solution to spatial resources information publishing systembased on ArcGIS Server; Then through the independent research anddevelopment of "rare character retrieval software", solves the rarecharacter and the GB character integrated input and the rare characterdistribution question; United the function of renewal project informationmanagement publishing system, proposes the system solution, as well asreasonable database structure; Finally, through developing the spatialresources information publishing system, the on-line documentmanagement system and the renewal project information network,organizing and the managing renewal information according to the region,realizes scientific style and the automated management for each kind ofinformation, and provides method of information inquiry and analysisbased on the network and the GIS technology.
