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

Abstract:

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.
