关于磁法勘探测点坐标的生成与工作部署图绘制

THE CREATION OF THE MEASURING POINT COORDINATE AND THE COMPILATION OF THE FIELD WORK ARRANGEMENT MAP FOR MAGNETIC FIELD SURVEY

在磁法勘探中,测点坐标的批量生成是必不可少的环节。提出了利用Visual C++编制程序生成1∶5万高精度磁法勘探测点坐标的思路,并编程加以实现;利用MapGIS的空间分析和投影变换功能实现了野外工作部署图的绘制。最后,将此方法应用于国家地调项目四川通安—小牛场地区远景调查项目磁测工作中。实践证明,此方法在工作中取得了较好的效果。

The generation of batches of GPS coordination is one of the most important tasks before the performance of the magnetic field work. This paper deals mainly with the batch generation of measuring point coordinate for magnetic field work by using Microsoft Visual C ＋ ＋ and Mapgis. The authors successfully designed and implemented a software witch could generate a batch of GPS points for magnetic field work and successfully used it in the Tongan-Xiaoniuchang magnetic survey project of Sichuan Province.
