Several measures assessing the accuracy of land-cover classification are available, e.g., overall and class- averaged accuracies. Also kappa statistic is widely used for this purpose. In this article, we discuss the properties of these criteria, and point out that the kappa statistic has an unfavorable feature. We propose alternative coefficients based on Kullback-Leibler information. Further, significance tests for the difference between the coefficients derived by classification results are established.
