In this study, the land cover types of the Yuntolovsky reserve were analyzed
on the basis of the classification results acquired using pixel-based image
analysis approaches. Aerial images were used to carry out the image classification
and ground truth data was collected from the available maps (Soil map, Topographic
maps), field observation and from personal knowledge. In pixel-based image analysis
supervised classification was performed using the minimum distance, Mahalonobis
distance, box-classifier through ILWIS 3.31, maximum likelihood classifier.
On the other hand, pixel-based image analysis unsupervised classification was
evaluated through ILWIS 3.31 software. During the implementation, several
different sets of parameters were tested for image segmentation and the standard
nearest neighbour was used as the classifier. The results of the classified images
have shown that the Maximum Likelihood approach gave more accurate results,
including the overall accuracy, higher producer’s and user’s accuracy
for most of the land cover classes in the studied region than those achieved
by pixel-based classification algorithms, such as: minimum distance, Mahalanobis
distance, box-classifier and cluster analyses.
Key words: landscape, remote sensing, image processing, natural heritage.
