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.
