Abstract
KED, the Kriging with External Drift, is one of the spatial statistical method for estimating some distribution from the discrete spatial sampled data set about the research field. The KED uses the kriging method (Matheron, 1973) with some auxiliary map to minimize the estimated error. The KED procedure was performed by the R-Language (Ihaka and Gentleman, 1996) using some geostatistical libraries. The auxiliary maps required by the KED were prepared by the authors with some GIS applications. The 3-dimensional geographic representations for the estimated distribution were performed by the Google Earth (Google, 2011). In this report, the KED was applied to some Earth scientific information to show the fundamental scheme of the method.
