Design And Realization Of Spatial Data Publish System Based On WebGIS

Currently, GIS has been extensively applied in many society domains. With the rapid development of the computer technologies in software hardware and the network technologies, GIS has provided a new method for people to issue, lay out, and get all kinds of information within range of the world. Presently, Web Geography Information System (WebGIS) is a hot GIS technology points. WebGIS is a kind of network GIS based on web technical norms and communication protocols, it's a new technology used web technologies to enlarge and consummate. With the incessant development of internet technologies and the requirement of Geography Information System (WebGIS), using internet to issue and publish spatial data, providing functions to browse, query, analyze spatial data for people, has become a certain trend in the development of GIS.There are many methods to exploder WebGIS, such as CGI technical method, ActiveX control and COM component former technology, Plug-in board plug-in board technical method etc. Although they all can effectively exploder internet-based GIS system, but exist deficiencies, such as high technology requirements, rigor humanware requirements, exploder taking a lot of trouble, time and energy etc. However component GIS technology has easy to realize system alete integration, development language diversity, well expansibility, powerful retroactivity, fashionable visualization programmer style characteristics, so much more press close to actual demand of almost GIS users, have powerful life-force.The paper apply SuperMap of component GIS software, put WebGIS technology and information system integration, realize a map disposal, background information management, latticing browse rolled into one. Internet-based GIS electronic map Information service System. A data model of geographic grid based on GeoDataBase was analyzed and customized. SuperMap Yueyang city geographic grid contains ready-to-use data models that can be configured and customized for use at Yueyang city data base layer. A keystone of this new data model is superior modeling of Yueyang City data base layer and geographic grid that capture the behavior of real-world objects. A GIS system design process of software engineering is introduced, which includes a GIS needs assessment and a system architecture design review. The system architecture design review is based on requirements identified in the GIS...
