先分析在Au【ocAD环境中组织cIs数据的方法，包括图形链接属性数据的方法和cAD／GIs间数据转换的方法，然后指出传统的转换方法的不足之处，并给出一种数据解译器组成结构，从而可以有效地实现cAD／GIs数据的无缝转换。最后，以地籍信息系统为例，验证在AutocAD环境中组织GIs数据能极大地提高专题cls的整体性能。-In the first analysis method Au [ocAD environment organization cIs data, the method including graphic link attribute data and cAD/GIs between data conversion method, and then point out the shortcomings of the traditional conversion method, and gives a data interpreter composed structure, which can effectively achieve a seamless transition cAD/GIs data. Finally, cadastral information system, for example, verify that the organization GIs data can greatly improve the overall performance of the topic cls in AutocAD environment.
