The Design And Implementation Of Rural Land Contract Management Database

With the rapid development of Land and Agriculture information technology, the paper cadastral information couldn't reach its digitization process. For the land management modernized, it's necessary to establish cadastral management information system of graphics, ownership and image information.The paper analyze the purpose and significance of database construction firstly, the database construction of rural collective land and construction land has already achieved, but to the agricultural land, it had not begun these study yet. For Rural Land Contract Management has three elements: subject, object and content, the paper explains the specific coding rules of the ownership information in detail. By comparing the different platform of database construction, and analyze their strengths and weaknesses, learn that ArcGIS platform with flexible data editing massive data management, and powerful spatial analysis and other functions, so choose ArcGIS platform as the platform for building a database.Then combined with examples Shouguang City, analyze the content and the logical structure of the database, and then divide the layer content and property fields physical design. designed the technical route of Rural Land Contract Management database construction in detail: Firstly, prepare the source data and the relevant information, secondly, with measurement combined with graphical methods collecting data and editing with CASS and ArcGIS software, and then based on logical design model to construct database, finally, load the processing data into the cadastral database. The data stream as a clue, discusses the data collection, editing, and processing in detail to demonstrate above design. Finally, discusses data quality control briefly.
