Spaital interpolation techniques

Abstract. The stick of this training is to investigate the effects of Inverse Distance Weighted interjection and Ordinary Kriging on a discrete spatial data set. By interpolating the discrete data hints with three different techniques observations turn in been do on the resultant raster surface produced. The test data use for this is a 300m2 surveyed area of the Waiotahi Valley east of Tauranga, the conf utilize foretelling models risquelight the difference visually and statistically and answer to a item the question of which is the almost effective. The realisation was made t chapeau the top hat fitting model for the data was statistically an eight sector ordinary krige with the spherical model, visually the assessment was different; the IDW supporter sector surface proved to be the best. Introduction and aims. The aim of this study is to the ESRI ArcMap Geostatisitcal Analyst to produce prediction surfaces from discrete point data, this entrus t allow for the visual and statistical selection probe of the most appropriate model for the data set. For comparitive purposes the majority of the parameters have been interchangeable and the default 10 category view of the surfaces used for the indication of result. The point data used for the study was placid in 2002 by the author finished the use of a conglomeration station and handheld GPS.

By predicting several surfaces done various interpolation methods it is hoped to comment on significant differences and similarities produced through the process, commenting on the quantitative and qualitative properties of the data. The hillslope used for this study resi! des in the Wiaotahi Valley, an min east of Tauranga on a platau above the ring alluvium planes. The reason for interest in this area is repayable to the high erosion and uplift rates that the area suffers from, the hillslope in question has risen over...
