摘　　要：在分析GIS和CAD数据模型的基础上,探讨了数据集成的方法。提出利用直接转换模式进行图形数据集成,利用集成数据字典方式解决CAD图形数据的转换和编码、语义表达的统一问题,设计了数据集成结构和具体的集成数据字典,并结合实例进行了论证。研究表明,利用该方法不仅可以节约成本,而且还能提高生产效率。Based on the expatiation to data model of GIS and CAD, the method of data integration is analyzed. It is put forward that used the direct conversion scheme to integrate the graph data, and used the integrated data dictionary to resolve the unification problem of code and semantic expression in the course of data convert. Designed the data integrated structure and integrated data dictionary, demonstrated the data with the example, It is indicated that the method is economic, effective and valuable to practice and spread.
