Research And Implementation Of Da An Irrigation Area Land Properties Classification Management Information System

Geographical Information System(GIS),It uses geographical space database and geographical model analysis method, so it can provide lots of spatial and dynamic geographical Information. Recent years, GIS's development is very fast, GIS's effect is also more and more abroad, it can solve management and programming in basic establishment, such as roadway , transmit electricity , even the area's exploitation such as city programming, population programming and collocation, GIS exert function very largely. This article introduces GIS's query and edit function, it combine DaAn Irrigation's characteristic, exploring DaAn irrigation area land properties classification management Information System.DaAn Irrigation of Jilin province locates the SongNen western region, NenJiang river's right bank, the central part in DaAn City, the engineering makes use of the ancient course of NenJiang river and DaAn river, making stronger and strengthening the province merchandise food base construction of Jilin, guaranteeing the national food safety, recovering and improving the ecosystem environment of the district is《the province national economy of Jilin develop "15" programming》《,develop the province of Jilin old industry base programming》and《the province water conservancy of Jilin develop "15" programming》's emphases engineering. It is also become the important soils project in the country of western. Before the irrigation develops, research to manufacture the property classification management information system that the development infused the area land, the realization infused the tiny machine of the area management work to turn, is important measure that the push our country infuses the area management work modernization and norms to turn. Along with the technical and quick development of information, information processing method is being changed direction the calculator by the handicraft gradually, infusing the area management work to delivered the speed and credibility to also put forward the higher request to the information, constructing the efficient, dependable Irrigation property classification of the area land management information system is need of the development.This article combine DaAn irrigation of Jilin province , making use of the GIS the space information management and analytical function, taking the property of DaAn irrigation as the basis, matching mature graphics technique and the database techniques, establishing DaAn irrigation area Land properties Classification Management Information System.The whole system adopts Windows operating system and Visual Stuadio.NET 2005 as exploitation tool, adopting C# language, database is used files form, adopting ESRI company's Shape files's .dbf files as property files. the system adopts ESRI company's MapObjects, it can use GIS's function in the Visual Stuadio.NET 2005, so realizing Geographical Information System's query and edit function.The property classification management information system includes DaAn County's data sub- system and each village sub- system. The whole system have four modules: Input module , query module, edit module and output module. Input module mainly complete the original data's input, among them include total diagram in DaAn county, big nine villages of Anne County and 53 country; query module mainly complete to browse and search operation towards area geography position, among them include the map to zoom in, zoom out, pan, whole diagram manifestation and so on; Edit module can complete to each area information to increase, modify, delete and the information record into the operation, among them including to increase some object, line object and polygon object and increase to note to record, can also to belong to data to carry on re- recording to go into or modify, the object deletes the etc.; Output module includes the map to print, keep the etc., can carry on printing the exportation to each current district, and can keep for other sketches format document, such as the BMP, JPEG etc. format. The spatial-data and attribute-data of the MIS for irrigation district have adopted the way of file management. The spatial-data is managed by SHP file , The attribute-data is managed by DEF file. The figure and attribute-data are related through the only m number to realize two-way inquiry.
