Study on Precision and Visualization Effects of Three Interpolation Methods

MAO Jian et al(College of Urban and Environmental Science,Tianjin Normal University,Tianjin 300387)  
Based on the analysis of Kriging interpolation,Inverse Distance to a Power interpolation and Nearest Neighbor interpolation method,the interpolation effect of three common spatial interpolation methods in the mountain terrain of Jixian Tianjin are analyzed.The expanded uncertainty and the visualization effect are used to measure the accuracy of three commonly used interpolation methods.The results show that Kriging interpolation method is more suitable to generate DEM in the mountain terrain.
