DXF格式数字地形图坐标转换软件开发研究

DXF格式文件是CAD图形开发中最常用的图形交换格式之一,由于其便于读写操作的特点,逐渐发展成为一种国际通用图形格式。分析研究了DXF文件中实体数据存储规则,然后选用C#语言实现了脱离CAD环境,直接操作DXF文件,从而完成图件坐标转换的功能。最后结合具体的工程实例验证了软件的正确性。

Research on Coordinate Conversion Software of DXF Format Digital Topographic Map

The DXF format is the most commonly used graphics CAD Graphics Interchange Format. Because it is easy to read and write, gradually it is developed into auniversal format. This paper firstly studies the entity data stored in the DXF file, then uses the C# language to operate the DXF file directly and this is independent of the CAD environment. Thus the map coordinate conversion function is completed. Finally, combining with the specific project example, the correctness of software is verified.
