Effects of different sampling densities and pixel size on kriging interpolation for predicting elevation

Elevation of earth surface can be modeled into several forms, i.e. height points, contour, Digital Elevation Model (DEM). DEM as a continuous type of elevation data is generated mainly from height point data. The accuracy of DEM depends on many factors; which one of them is the level of sampling density of the height point used as the input of interpolation… CONTINUE READING
