GIS-based analysis of spatial interpolations of sediments grain size in Heini Bay
基于GIS空间分析的海底表层沉积物粒度分布特征插值研究

Interpolation applications on grain size parameters distribution of surface sediments in Heini Bay with GIS-based methods were discussed.Four interpolation methods(IDW,Kriging,Spline,NN) were compared and the factors influencing the interpolation accuracy were discussed from several aspects.The results indicate that considering interpolation accuracy and spatial expression IDW is relatively best among four interpolation methods in process of grain size parameter interpolation in Heini Bay.But bulls eye effe...
