摘要
As the observation data is insufficient, two-dimensional interpolation of irregular discrete data is widely used in geophysics. In this paper, the authors researched and implemented a two-dimensional interpolation of natural neighbour algorithm, which will be applied to the MT 2D inversion real-time imaging. The results show that the method has high accuracy, effective, fast and easy simulation of the data with terrain.
