PDF格式地形地质图到MAPGIS格式转换方法探讨

Discussion on Transformation PDF Format of Terrain and Geological Map into MAPGIS Format

通过讨论PDF文件特性,提出了PDF格式地形地质图到MAPGIS格式转换途径,介绍了三种不同PDF矢量图形转换软件,简述了其选项设置及转换流程。通过对两个不同形式的PDF格式地形地质图进行转换实践,对比研究了转换的实际效果。笔者认为,先将PDF矢量图形转换为DXF格式,再将DXF导入到MAPGIS软件中进行必要的编辑处理,是比较可行的PDF文件利用方案,对实际工作具有一定的现实意义。

By discussing the PDF file properties, the authors propose transformation approach from PDF format to MAP- GIS format, introduce three different PDF conversion software of vector graphics, briefly outline option setting and conver- sion process. The authors believe transformation of PDF vector graphs into DXF format, and then introduction DXF into MAPGIS are feasible utilization plan of PDF file. It is of certain significance to actual work.
