Application of the Spatial Interpolation Methods in GIS
Data that has certain rules is needed on the research of GIS,but in most cases the data we can get directly is discrete and irregular.So we need to convert data which is discrete and irregular to the one has certain rules through the spatial interpolation.Common interpolation methods are described in this paper.And then the application of the Spatial Interpolation methods in GIS is introduced through the creation of DEM.
