简捷准确的观测系统几何库定义方法

A convenient accurate method for defining the geometry library of field observation system

在地震资料处理中，观测系统几何库（GE库）的定义往往较为繁琐，本文介绍一种较为快捷且准确的定义方法。该方法依据野外观测系统图及仪器记录班报所反映信息的规律性或特点，并通过程序的设计技巧来实现原始数据的快速准确的读取输入。本方法既适用于二维，也适用于三维。文中以二维资料为例进行介绍。

In seismic data processing,the definition of geometry library of field observa-tion system is very troublesome. A new accurate definition method is recommendedhere. With advanced softwares, this meth0d achieves fast accurate read-out and in-put of raw data in terms of field layout chart and s0me regular data in operator's logbook. This method is suitable to both 2-D seismic data and 3-D seismic data. It isapplied to 2-D seismic data in this paper-
