Abstract: A stochastic approach to interpolating sparse observation records in geography referred to as the "Kriging technique" has been developed by Matheron (1970) but was named after D. R. Krige, who first applied some of the concepts underlying this technique to assessing the gold contents of the South Africa mines.A fundamental concept of the kriging theory, i.e, the variogram, is analyzed in the light of the deterministic development and is given a welldefined physical meaning. By minimizing the sum of square deviation between the estimating and measuring values with the constraint of unbiased estimation the "Kriging" system equations could be derived. In principle, the kriging technique should provide more reliable estimates, since the theoretical variogram incorporates a larger amount of information than that related to the available recordls.The primary advantage of the kriging technique is the ability to provide an interpolation value of unmeasured points using available information. The kriging technique could be applied in geography, especially in surface hydrology, groundwater, soil moisture, the regional planning and network design.
