The Study, Based On Webgis Second Land Survey Results Information Management And Query System

In recent years, with the rapid development of computer networks, the WebGIS-based Internet has completely changed the structure of GIS models, carries on each kinds of information on Web to issue has now become a hot application, GIS is also from a closed desktop systems development to the mass-oriented network of open systems. WebGIS is the organic integration of GIS and network. It makes the application of GIS expand to every aspect of the society and has become the popular information tools.This article applies the WebGIS technology the second land survey achievement information in the issue,to take advantage of more mature platform MapGIS7.1-IMS, combined with the results of land survey information on the characteristics of the development of the outcome of an investigation of information management and query system. After the completion of the system can be provided in the Internet of some counties and cities in the survey results of the information, the user through a browser can easily understand that the status of land use, land ownership, information such as basic farmland. Makes the investigation of information digitalization and networking, thus better for the land department in charge of Services.This article in analyzes the second land survey present situation and in the WebGIS theory foundation,introduces specialized geography data management platform GIS, make use of MapGIS7.1-IMS+SQL Server 2000, unifies the Visual C#.NET development language, realizes to investigates the achievement information the management, has established based on the WebGIS technology land investigation achievement information management and query system. First of all papers for the second land survey of the profiles, both at home and abroad in the land area of information dissemination as well as developments in the research and application of WebGIS the status to do a brief introduction; followed on WebGIS concept, main features, architecture and key technologies to do the more detailed analysis; and then on the current major WebGIS platform software carried out a detailed comparison, the ultimate combining the results of the second land investigate the characteristics of information, select ZondyCyber to Wuhan's MapGIS7.1-IMS platform to the development of based on WebGIS the outcome of the second land survey information management and query system. And the results of the second land survey information management and query system for the system design, database design and functional design, and carried on the practical application take the Kunming Guandu District correlation data as the example, the effect has been good.
