DWG地图到改进规则SVG地图的转换方法

A Conversion Method from DWG Format Map to Improved-rules SVG Format Map

提出了一种扩展属性数据的自动化计算机辅助设计(AutoCAD)标准格式(DWG)地图到改进规则的可缩放矢量图形(SVG)格式地图的转换方法.通过定义改进的SVG规则,将DWG格式中的基础图形数据和扩展属性数据合并在一起,在SVG中作为一个整体表示,保证了转换过程中的数据完整性.同时,通过定义SVG分层规则,突破了DWG中扁平图层的限制.应用验证证明该转换方法是有效的.

We propose a method of converting AutoCAD standard format （DWG） map with extended attribute data to improved-rules scalable vector graphics （SVG） format map. Both graphical data and attribute data are put together and regarded as a single object in SVG by defining improved SVG rules, which assures the data integrity of the conversion. Meanwhile, flat hierarchical management in DWG is improved in SVG by defining SVG hierarchical rule. Experiments validate that the conversion method is effective.
