Spatial interpolation approach based on IDW with anisotropic spatial structures

摘要: In many interpolation methods, with its simple principle, Inverse distance weighted (IDW) is one of the most common method. There are anisotropic spatial structures actual geographical phenomenon. When IDW used, should be considered. Geostatistical theory has a characteristics exploring structures. this paper, approach based on proposed. The DEM data tested in paper to prove reliability considering Experimental results show that can improve precision when sampling feature.
