基于GDP系统AVG数据格式与开发研究

GDP系列大地电磁系统是美国zonge公司的产品,自上世纪八十年代进入我国后,该系统在很多部门得到了应用和推广,在资源勘探、工程地质、灾害探测等领域发挥了巨大作用。由于zonge公司随仪器配套的软件有限,在实际应用中,需要根据实际情况要求进行一些特定的数据处理。人们在后期数据处理中涉及最多的是AVG数据文件,为了更好地进行二次开发,有必要对AVG文件格式进行研究。鉴于此,这里先对AVG文件的数据格式作了详细的解释,再提出在读取过程中所要解决的问题及其解决方法,然后给出了读取其数据格式的主要程序代码,最后给出了读取文件的实例,说明了程序的正确性。

The study and development based on the AVG data file syntax of GDP series device

The series device of GDP is produced by the US company Zonge,which has been used in many fields since 1980s,such as,resource prospecting ,engineering geology,disaster survey and so on. The according processing program of GDP series device is,however,limited in the practice function. As a result,there are some difficulties in processing the file which has AVG as extended file name.To conclude,we have to study on the AVG file format.This essay introduces some explicit explanation on this data syntax,as well as giving program code how to read the data syntax. Finally the authors present a reading file example, and prove that the program is sound.
