2.6 Accuracy assessment of classified land-cover/ use maps
The accuracy of produced maps was examined quantitatively with validation data produced by visual expert interpretation of multiseasonal Landsat imagery, high-resolution satellite imagery available via Google EarthTM mapping service and the use of field-collected data. Accuracy assessment was performed for 1985, 1998 and 2016 maps. In total, 1,277 points were used to evaluate the accuracy of the thematic maps, which were produced with a stratified random sampling approach. Overall, producer’s and user’s accuracies were calculated based on contingency tables between validation data and classified maps.
