Popis: A method is proposed for statistically evaluating the accuracy levels of maximum likelihood classifications and representing them graphically. Based on the concept that the heterogeneity of maximum likelihood membership probabilities can be taken as an indicator of the confidence for the classification, such a parameter is estimated for all pixels as relative probability entropy and represented in a separate channel. After a brief presentation of the statistical basis of the methodology, this is applied to a conventional and two modified maximum likelihood classifications in a case study using Landsat TM scenes. The results demonstrate the efficiency of the approach and, particularly, its usefulness for operational applications.
