Application of ordinary Kriging method in data processing of magnetic survey

Ordinary Kriging method is a widely employed method for interpolating and estimating magnitude from digital magnetic data. The aim of this paper is to discuss application of ordinary Kriging method magnetic survey. Firstly principles of ordinary Kriging method and magnetic survey are introduced. Calculating steps of ordinary Kriging method are listed secondly. In the end, several examples of applications of the method in data processing of magnetic survey at one mine field are presented.
