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80年代进入我国后,该系统在我国很多部门得到应用和推广,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。鉴此,本文先对AVG文件的数据格式作了详细的解释,其次提出了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 AVG Data File Syntax of GDP Series Device and Its Application

The series devices of GDP is produced by the US company Zonge, and has been used in many fields since 1980s, such as resource prospecting, engineering geology, disaster survey and so on. However, the according processing program of GDP series device has some shortcomings in practice, which needs particular data processing. Due to AVG data file being involved in practice, which needs studies in order to be further developed. This data syntax is explained in detail, the problems in existence and the solving method is proposed, as well as the program codes on how to read the data syntax is given. Finally an example is presented, which proves that he program is valid.
