Urban Cadastral Database Construction

At present, with the rapid development of China's national economy and the rapid development of urban construction, making frequent changes to cadastral information, urban land use and land ownership has undergone great changes, cadastral information is also growing. Faced with such frequent changes in the number of large, rich source of cadastral information, the traditional cadastral management can not meet the needs of modern land management. The traditional management of cadastral data file as the carrier is simply a range of data will be combined into a map sheet of papers kept up a continuous and seamless for the original to create an artificial split of geospatial phenomena, limiting the application of State Land Cadastre Flexibility and efficiency. Meanwhile, China's urban construction of cadastral information, the increasing demand for land cadastre data, centralized management, service applications, centralized management. Faced with these problems, by means of modern science and technology, especially GIS and database technology means improved urban cadastral management, improve the urban cadastral level of urban development has become inevitable.This paper intends to land management based on the requirements of the city in Jiangxi Province as the study area Xinfeng to Xinfeng urban construction project information database as the data source, use of the existing theories and methods, based on national and technical specifications related to Jiangxi Province, Standards, through the application of software to build Cadastral MapGIS database, county to discuss the construction of Cadastral Database in order to build the database can be Cadastral some guidance, to improve the efficiency and quality of the library building purposes.Thesis, access to domestic and foreign scholars through the research theories, methods, and personally participate in the process of building a database using the theory with practice, the use of MapGIS technology and database technology, combined with the city of Jiangxi Province Xinfeng cadastral database building project City Xinfeng County, Jiangxi Province on the basis of the database needs analysis, combined with the actual conditions of the project and building a database based on database technology roadmap for the construction of rational design; designed the graphics database, attribute database; designed the database management function; design of the outer Industry technology roadmap land survey, ownership survey routes, cadastral mapping routes; designed based on the foreign trade of electronic data, vector data conversion, data based on digital orthophoto, scanning vectorization, 3S integration of PDA-based data sources of different data collection Line; design data inspection route; design data storage line; designed to update the county line of the cadastre database; external sector made a detailed land survey; on different data sources for data acquisition and processing were described in detail; of Xinfeng City cadastral databases were described in detail the specific steps; quality evaluation of results, database security management were described in detail; for database management are introduced in detail; on the county's cadastral database updates made a comprehensive elaboration; through the design model Algorithms and write computer programs to complete the housing and housing close inspection to determine overlap.Studies have shown that the use of this thesis research Cadastral Database, the successful completion of the Xinfeng Town Cadastral Database. This study will give other parts of the database building to be used for reference and guidance; will apply the results of Xinfeng database daily management of land, better land management Xinfeng improved efficiency and effectiveness; database After the completion, you can easily share information, in Jiangxi Province and the country's land resources to provide data information management, better management of land resources for services for the national economic construction.
