Database construction of general land use plan: A case study of Changzhou National Hi-Tech District (CND)

The informatization of management is a trend to adapt to the new managerial requires. In order to avoid the existence of information islet, the development direction of land informatization has focused on the construction of database. Instead of “Mange land by maps”, the mode of land management has become “Manage land by database”. The database of the general land use plan can be separated to three parts: spatial database, table database and metadata. GIS is the best tool to construct planning database because of the complex relationship between tables and the diversity of geographic data. Some preliminary work such as collection of literature and statistics should not be overlooked. In this paper, the details of the database construction process associated with some key issues are illustrated. Proper choice of software and applications can improve the efficiency of your work. At last, some related issues are discussed: coordinate system related issues, prime farmland issues, tolerance and resolution, and database capacity.
