地质制图中MapGIS数据与CorelDRAW数据转换方法探讨

Discussion on converting MapGIS data into CorelDRAW data in geological mapping

简述了地质制图软件的特点,分析并讨论了MapGIS数据转换为CorelDRAW数据的传统方法及其特点。针对传统转换方法存在的数据量大、不易修编及字体、符号、颜色、线形易丢失等缺点,经过对地质制图数据转换软件和转换格式进行调查、对比、筛选,确定3DMine作为数据转换工具、dwg(dxf)作为中间转换格式的方法。基于3DMine方法转换的数据比传统方法转换的数据更好地适应CorelDRAW软件,该方法操作简单、出错率低,克服了传统转换方法的缺点,极大提高CorelDRAW的制图效率。

The article briefly introduces the characteristics of software used for geological mapping,analyzes some traditional methods and characteristics of converting MapGIS data into CorelDRAW data.There are many disadvantages in traditional methods,such as large amount of data,difficult to modify,and easy to lose the font,symbol,color and line type.In view of these disadvantages,the method is choose by investigation and comparison of traditional methods,selection of transformation software and transformation format which uses 3DMine as the transformation tool,.dwg(.dxf)as the intermediate transformation format.The data transformed by 3DMine is adapt to CorelDRAW,and better than the traditional methods.In comparison with traditional methods,the method is simple to operate and has fewer errors,and greatly improves the mapping efficiency in CorelDRAW.
