Ordinary Kriging, OK, and Regression Kriging, RK, are the spatial statistical methods that are possible toestimate a horizontal distribution in a study area from discrete data. OK is the method which takes account ofonly spatial auto-correlation structure of the data, while RK is the method which takes account of an interrelationshipbetween spatial auto-correlation structure and some auxiliary variables to minimize the estimation error.Analytical processing for OK and RK methods was performed by the R-Language (R Core Team, 2012)and its some additional libraries. The auxiliary variables required to perform RK method were prepared by aGIS application, Quantum GIS (Quantum GIS Development Team, 2012). The 3-dimensional geographic representationof the estimation maps was performed by the Google Earth (Google, 2012).In this report, OK and RK methods were applied to one of the Earth scientific information, SPM (SupendedParticulate Matter). Then, these methods were considered by comparing two estimation maps, and finallyconsidered qualitatively by displaying these maps in the Google Earth.
