摘要
剖析了Surfer的数据文件和MapGIS的数据文件格式,提出了其相互转换的方法,并编制了转换软件.特别是指出MapGIS网格化的ASCII码文件,即DET文件,可以通过简单的编辑形成通用的网格化GRD文件格式,不应当再进行网格化.提出利用Surfer勾绘特定的地球化学元素异常图,转成MapGIS修饰出版的实用制图程序.
The GIS software of MapGIS and Surfer are commonly applied in geologic research and exploration. However, the data of one sort cannot be adopted easily by each other. By analysis on the data file formats of Surfer and MapGIS, the paper proposes a method to convert the data between the two types of software. A conversion-software is complied. Particularly, the grid ASCII file (DET) of MapGIS can be formed by simple editing, without transfer to grid. A practical program is made to draw the geochemical anomaly map by Surfer and then to convert into MapGIS format for publishing.
