Abstract
At the local regional geoid determination, the application of mathematical model to compute abnormal height is a method commonly used in engineering. This paper focuses on the double-curved, inverted double-curved surface, cubic surface of three different kernel functions fitting the multi-faceted function to compare and research the issue about how to select the best smoothing factor. The results show that the three methods is feasibility in determining more complex terrain regional geoid.关键词
