Spaital interpolation techniques

Abstract. The aim of this study is to investigate the effects of 'Inverse Distance Weighted' interpolation and 'Ordinary Kriging' on a discrete spatial data set. By interpolating the discrete data points with three different techniques observations have been made on the resultant raster surface produced. The test data used for this is a 300m2 surveyed area of the Waiotahi Valley east of Tauranga, the various prediction models highlight the difference visually and statistically and answer …
