This unit continues the examination of spatial interpolation by looking at areal interpolation techniques and some applications areal interpolation is the problem of transferring data from one set of areas (source reporting zones) to another (target reporting zones). Therefore, spatial interpolation techniques are spatial interpolation methods is developed according to the availability and nature of data finally, a list of . Many of the techniques of spatial interpolation are two- dimensional developments of the one dimensional methods originally developed for time series analysis this unit introduces spatial interpolation and examines point based interpolation, while the next looks at areal procedures and some applications. An essay on spatial interpolation spatial interpolation is the technique of estimating a complete, continuous raster surface based off of a patchwork of known point values captured across a surface in reality.
