Utilizing a improved contour plotting method based on delaunay triangulation network in geologic hazard prevention

Abstract

Traditional contour plotting method, limited by linear interpolation, has much error in studying regional variables,. It is advanced in this paper by utilizing nonlinear interpolation and triangles mass points interpolation methods, which greatly improve the fitting precision. New contour plotting method is validated in meteorological early-warning system of geological disaster in Guangdong XiBeiJiang region and the verifying result is satisfied.
