State-level Land And Resources Data Center Design And Realization

Along with the land resources informationization work thorough and "the digital national land" the project implementation, the land resources foundation information digitization degree enhances day by day, the land resources management section's working transits gradually from the original pure manual way to the electronic work pattern. Working's gradual transformation, caused the land resources Control section to have the renewal to the work software and hardware environment, a higher request. Under the recent economic development environment, the land resources use way trend multiplication, quick change, widespread resources use way, this enables originally by way output and so on traditional document, blueprint land resources information to meet the need, the land resources Control section and social various domains is also getting bigger and bigger to the land resources information demand, grows day by day to data sharing and information service's request.Land and Resources Data Center is a large-scale land and natural resources data warehouse, which is the topic from many different databases in accordance with certain rules established. State land resources data center, as the middle hub of Land and Resources System data, land and resources in the whole system of vital status, state land resources data center, land and resources directly affect several stages of data exchange and data consistency, integrity. State land resources data center of a major role is state land and resources for data storage, management, computing, analysis, display and applications for land management decision-making basis for the use of land resources and providing data to support change.This paper first analyzes the research background of subject, and on the status of the data center building an in-depth discussion and analysis. Then rely on Yunnan Province Chuxiong e-government system of land and resources in support of the project was designed based on GIS state land and resources data centers. This system has realized core functions and so on system administration, inquiry browsing, change project management, data output, client side disposition.System administration function including to administrative regionalization, essential data and documents data topic and special level establishment, data depositing way and data pool establishment.The inquiry browsing including the spot, the line, the area distinction's attribute inquiry, attribute structure's browsing, calculates and the area quantity from the quantity calculates and so on.The management change project is an important work of the national department's daily work, which including the essential data change duty's issue and data packet's output, realizes to the essential data real-time change, as well as to essential data change project examination, statistical management.Data output including cutting out output essential data and compression derived data and so on.The client side disposition namely carries on the management to the user, namely to visits the land resources data central client side the user newly built, the deletion and the password revision, as well as to each user's access authority and operation jurisdiction establishment.
