Abstract
The aim of the paper is to present the possibilities of geostatistical interpolation kriging method using in the process of generating digital terrain models (DTM). The source of data is a direct measurements realized with a precision GNSS positioning kinematic measurement technique RTN. Kriging algorithm was analysed, especially in the meaning of a semivariogram every step. Theoretical semivariogram selection influence on the interpolation accuracy was verified, and thus, the accuracy of the resulting terrain model. Moreover, phenomenon as drift and anisotropy were tested and their influence on the result. The size of the effect was determined with two parameters: the kriging variance and root-mean-square error (RMS). The research results let the authors conclude that proper interpolation by kriging algorithm is a very complicated process and should be based on a geostatistical knowledge. By a right interpolation with the kriging, an accurate surface model can be gained which can reveal every single morphology details.
