What is Ordinary Kriging with GRASS-R about?

This document provides an example of using GRASS and R to perform ordinary kriging interpolation of elevation data. 300 random sample points were generated and elevation values extracted from a DEM raster. The data was loaded into R and a linear variogram model was fit. Ordinary kriging was used to interpolate elevation values across the study area. The results were written back to GRASS and compared to interpolation using regularized splines with tension, finding similar root-mean-square error values betwe
