The smoothing effect of ordinary kriging is a well-known dangerous effect associated with this estimation technique. Consequently kriging estimates do not present global accuracy, which is a desirable feature for interpreting patterns of extreme attribute values. A four-step procedure for correcting the smoothing effect of ordinary kriging estimates is shown to be efficient for the reproduction of histogram and semivariogram without loss of local accuracy. Besides this procedure provides a unique map sharing both local and global accuracies. Ordinary kriging with a right correction for smoothing effect can be revitalized as a reliable estimation method that makes a better use of the available information.
