Urban Land Research And Implementation Of Land Appraisal Database System

Urban land grading and evaluating data is an important basis for the supply of land and building, "Urban Land Classification Gradation and Evaluation Database", to optimize the allocation and rational use of limited land resources, give full play to the land of the economic, social and ecological benefits of the local development and construction to ensure economic and social sustainable development and achieve cross-century development goals, is of great significance.Urban land classification and benchmarks for premium calculation and application of results-based management as a Land Information Infrastructure and as part of e-government, as well as this business has been implemented for many years already mature technology and software systems, and a large number of lines of data and applied the results of urban land management among the. However, as this business to carry out earlier, the formation of various types of software system data format can not be shared between various systems, let alone the outcome of the unified management of data and in-depth application.This database system based on the relevant procedures issued by the Ministry of Land Resources and the local urban land classification of the practical requirements, the application of computer software technology combined with GIS technology, using MySQL database as the data storage system as a whole center and MySQL server as a background management system, MySQL database can effectively manage the vast amounts of data and follow the OpenGIS properties of space vector, raster image data. According to the status of data collection, database development and application of this management tool designed with the underlying technology developed routes to complete the classification, gradation space vector and attribute data, database construction, fast in the database platform for storage and data management in a series of functions.
