The Design And Implementation Of Urban Cadastral Database

With the rapid development of China’s urbanization, the expansion of the scale ofurban construction, the rapid development of the present potential of cadastral datatimeliness of access to increasingly high demand, frequent changes in ownership ofurban land, cadastral information is also increasingly update, the amount ofinformationyear by year.In the face of such a huge and frequent changes of cadastralinformation, the traditional paper cadastral management methods can not adapt tomodern cadastral information，the cadastral management tools from the original paperupgrade to Computer Management.The Applied Computer Management Land andResources Bureau in the second land survey to establish a database management system,so that the land and resources information technology, network management andautomation, not only over the data to better grasp the change cadastral shared.Firstly, the significance of the study of the construction of cadastral databaseanalysis, summed up the domestic development of the status.Through in-depth analysisof the characteristics of the urban cadastral data in the spatial data and cadastral datapresented data organization and management methods. Selected according to thecadastral database of Hengfeng County building a database platform.The contents of the database and the logical structure of the detailed design of theUrban Cadastral Database Construction route.Graphic data in the database, the attributedata acquisition, assignment, data checking, storage and output of the results of buildinga database of more comprehensive analysis.And cadastral data acquisition and processingcarried out in-depth study, attribute entry, to CASS figure in the storage means, throughthe practice has proved the feasibility of the method.Finally, Hengfeng County Cadastral Database Construction instance, discusses in detail the basic situation of building a database, data processing, in order to establish adatabase Kuti and gives the results of the study of building a database tables andmaps.Given the results of the library and in the end the quality evaluation.Theory and Practice of the designed route feasibility of building a database tooperate, using the SQL Server+MapGIS means suitable for the construction of smalland medium-sized database, attribute entry, CASS Figure means to resolvethe drawbacksof the means of entry, reducing the workload of manual entry and the attribute entry,while the figure is a consistency check.
