Design And Realization Of Urban-Rural Land Use Planning Integration Information System Based On AE

In order to improve the efficiency of the land use planning and management work, a batch of information systems and related basic databases have been sequentially built and put into use, with the covering range for main business of land and resources planning. However, most of the systems are designed for specific application, and resulting in the data scattering and sharing uneasily, the data and business circulation between planning departments is seriously restricted. Thus, it is necessary to build an integrated platform for urban-rural land use planning based on the conformity of each independent, dispersed system and database, using the modern technology of computer, database, spatial information, especially GIS, so as to share massive data.According to the analysis of the needs of land use planning operation, a solution for land use planning integration information system based on ComGIS is put forward, using technologies such as computer, database, and GIS, the general framework and integrated database for mass of shared data is constructed also. On the basis of this, AE (ArcGIS Engine) component package, ArcSDE spatial data engine, ODBC Open Database Connectivity, SQL Server 2005 large database and VC#.NET programming language, are chosen to realize the urban-rural land use planning integration information system. The main research contents and achievements of the thesis is depicted as follows.Firstly, according to the characteristics of data and the needs of land use planning operation, the data association integration mode with data engine such as ArcSDE and ODBC, and the function modules integration based on stratified COM technology are introduced. Then, the general framework for this system is designed.Secondly, the integrated database for land use planning is constructed, the data extraction and organization mode for heterogeneous source spatial data, and the design mode of meta data form and view for attribute data integration are researched especially, then the combined invocation for multi-source data of land use planning is realized.Thirdly, with the existing general framework and integrated database, the land use planning integration information system is programming realized, using ArcGIS Engine, ArcSDE, ODBC, SQL Server 2005 and VC#.NET. Practice shows that this integration system is more or less practical for planning of land departments.
