Update The Design Of Large Scale In Weifangbasic Geographic Information Database

At present, Weifang city to promote the construction of "digital city" positive ", as the core of digital city" construction is crucial, fundamental geographic information database construction. Weifang city has completed the construction work in advance, the realization of the model of spatial database management of large scale terrain data of Weifang city. But the city development change rapidly, used to reflect the basic geographic information data distribution between city geographic space must be constantly updated with the development of the city, in order to ensure the reality and accuracy of basic geographic information database. For a completed basic geographic information database, how to realize the rapid update, and the fast changing social environment, in order to keep the reality and accuracy of basic geographic information database, is the "digital city" construction problems.In this paper, through this project on large scales of Weifang basic geographic information database update of Weifang City, according to the specific requirements of large scale basic geographic information database update, Weifang city to use a1:500large scale topographic map data repair measurement, digital line access to the potential of classified data, complete the graphics data and attribute data update, data processing, data storage, by combining the application of AutoCAD and ArcGIS, simultaneously address database update, improve storage efficiency and accuracy of the basic geographic information database, update; metadata and catalogs of Surveying and mapping results distribution service system update. Ensure the accuracy, completeness and availability of basic geographic information database.
