Urban Planning Data Storage System

The bringing forward of the concept of"Digital city"has change the way of urban planning management, digital the complicated system such as economy, population and environment through the advanced computer technology. This way is not only beneficial to rase the rationality and scientific of government decision and efficiency of urban planning, but also rase the timelineness of urban construction and validity of city management. Based on the present condition of urban planning management, we develop the research of urban planning data storage system.We study the physical truth of Ganzhou urban planning and use the experience of urban planning at home and abroad, choose the regulatory planning data as research object. First, we write code which adapt to the CAD data base on industry rules in favor of the change between different data formats; then base on .NET platform and C# language, through the ArcGIS Engine and Objects ARX2007 component, we change the data format by the rules. The factor is put the dwg data into personal geodatabase feature class and import into ArcSDE Geodatabase, so we can manage it by ArcSDE. The function of data preprocessing and transfer from CAD data format to GIS format intact and GIS data management are achieved. The system not only can reduce the complex of urban planning work greatly, but also make marked progress in efficiency and accurate of urban planning.
