Hodnocení změn krajiny v oblasti Jeseníků na základě historických a současných leteckých snímků

The thesis focuses on the development of the foothills of the Hrubý Jeseník Mountains in the Bělá pod Pradědem municipality. It compares the situation in 1953 (1955) with that of 2018, based on aerial photographs. Manual vectorization created maps of land use, supplemented by the occurrence of line and solitary vegetation. Subsequent comparison evaluated that the forest and the built up area were expanded and the arable land was converted into grassland, which was connected with the reduction in the intensity of farming. The landscape has retained its foothill character with typical line and solitary vegetation. Subsequently, the automatic image classification (unsupervised and supervised) was used to create a land use map, its accuracy was evaluated and both methods were compared
