Classification and
accuracies
The tool has been tested in the field (using mobile phones and tablet)
by end-users and found to be a suitable help in the assessment of the
status of the vegetation. Accuracy of the year classification is
currently in the order of 80% while overall accuracy of single image
classifications vary between 60 and 70%. A confusion matrix of the
annual classification in the same year as the ground truth is shown in
Table 3. The confusion occurs especially between classes in which
vegetation is very much alike, such as the confusion between willow
shrub and willow forest, and between rough natural grass lands and
production grasslands.
