| 摘 要： | 文章通过分析VCT和DXF格式文件各自的特点,制作一个包含CASS5.1图形库中所有图形的全集DXF模板文件,并建立VCT的要素代码和相应图形的DXF代码的对应,找到了数据格式转换的方法;用高级编程语言编程,分别读取VCT中的点、线、面、注记及宗地等要素,在DXF的实体段中写入相应的DXF代码,以读写文本文件的方式完成格式转换,从而使VCT文件可以应用在GIS系统中。

| Abstract: | The characteristics of VCT and DXF files are analyzed,and through making a DXF module file which includes all the figures in the CASS5.1 figure warehouse and building a relationship between the element codes of VCT files and the DXF codes of corresponding figures,a way of transforming VCT files to DXF files is found.Advanced computer programming language is adopted,and the figure elements such as points,lines,surfaces and annotations are read respectively,and then the corresponding codes are written into DXF entities,thus achieving the transform of file formats by reading and writing.txt files.Then the VCT files can be applied in the geographical information system(GIS). |
