地球物理数据处理解释系统中坐标转换的设计及实现

The design and software realization of coordinate transormation for the geophysical data processing and interpretation system

坐标数据作为基础数据涉及航空物探数据处理的整个过程,与数据处理质量和解释效果息息相关。笔者在调研分析地球物理数据处理解释系统需求的基础上,应用C++编程语言,结合坐标参数文件管理方式,完成了系统中坐标转换功能研制,并提供了标准化的API接口。经评估,转换后的精度,达到了航空物探数据处理要求。

Coordinate data, as the basis of the data involved in the whole process of airborne geophysical data processing, are closely related to the quality of data processing and interpretation effects. Based on an analysis of the requirements of geophysical data process- ing and interpretation system and the employment of C ＋ ＋ language, in combination with the coordinate parameter file management mode, the authors provided the standardized API interface, developed the function of coordinate transformation, and evaluated the con- version accuracy. The results have achieved the requirement of airborne geophysical data processing.
