| Abstract: | In drawing the contour map of geophysical data, suitable gridding methods should be chosen according to objective
environment characteristics and characteristics of data themselves. With practical examples, this paper deals with some common
gridding methods such as inverse distance to a power, Kriging, Minimum Curvatrue, Nearest Neighbor, Polynomial Regression, Radial
Basis Function, and Triangulation/Liner Interpolation, probing into their choosing means, applicable fields and parameter
installment. |
