摘要
G IS空间数据具有多源性的特征,为数据综合利用和数据共享带来不便,解决多格式数据源集成一直是近年来G IS应用系统开发中需要解决的重要问题[5]。DXF格式作为一种空间数据转换的事实上的标准,对于G IS软件来说,实现两者的数据转换具有重要意义。本文分析了G IS空间数据与AutoCAD数据模型的组织特征,在比较分析的基础上设计了转换方案,并就实现过程中的关键技术进行了论述。
GIS Spatial data is multisourced, and it is obstructive to data sharing. It is important that resolving data intergration of different formates in the process of GIS software engineering. DXF is a kind of universal format, so it is significative for GIS software to realize the data conversion between GIS and AutoCAD. In the paper the data model of AutoCAD and GIS spatial data were studied, the method of conversion was designed, and the key technologies were expatiated in the process of realization.
