The strongly eroded soils appear in the studied area as bright patterns, surrounded by darker soils, and they are well visible on aerial photos. Three approaches of interpretation of aerial photographs were tested: visual interpretation, pixel-based image classification, and object-based image classification. All three methods provided detailed maps of soil redistribution patterns. The bright areas as the areas of soil degradation characterized by erosion increased from 1949 until 2011 by 76%. A detailed map of areal erosion patterns was used for the validation of water erosion models. LS-factor of USLE and ED\u2019 index of USPED were selected for expressing the relation of real erosion to the terrain. The relationship between surface morphology and real erosion is very complex, and the tested water erosion models do not express it sufficiently. Therefore, the first and second-order directional derivative of the surface elevations with respect to the tillage direction has been tested. The absolute value of the first-order directional derivative showed better results and better corresponded with the real erosion pattern than the other morphometric characteristics. The findings suggest that tillage is the dominant erosion factor in the area.<\/jats:p>","DOI":"10.3390\/rs12244047","type":"journal-article","created":{"date-parts":[[2020,12,10]],"date-time":"2020-12-10T08:59:34Z","timestamp":1607590774000},"page":"4047","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Mapping Soil Degradation on Arable Land with Aerial Photography and Erosion Models, Case Study from Danube Lowland, Slovakia"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6644-1111","authenticated-orcid":false,"given":"Mari\u00e1n","family":"Jen\u010do","sequence":"first","affiliation":[{"name":"Department of Physical Geography and Geoecology, Faculty of Natural Sciences, Comenius University in Bratislava, Mlynsk\u00e1 dolina, Ilkovi\u010dova 6, 842 15 Bratislava, Slovakia"}]},{"given":"Emil","family":"Fulajt\u00e1r","sequence":"additional","affiliation":[{"name":"National Agriculture and Food Centre, Soil Science and Conservation Research Institute, Tren\u010dianska 55, 821 09 Bratislava, Slovakia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3539-7995","authenticated-orcid":false,"given":"Hana","family":"Bob\u00e1\u013eov\u00e1","sequence":"additional","affiliation":[{"name":"Department of Cartography, Geoinformatics and Remote Sensing, Faculty of Natural Sciences, Comenius University in Bratislava, Mlynsk\u00e1 dolina, Ilkovi\u010dova 6, 842 15 Bratislava, Slovakia"}]},{"given":"Igor","family":"Mate\u010dn\u00fd","sequence":"additional","affiliation":[{"name":"Department of Physical Geography and Geoecology, Faculty of Natural Sciences, Comenius University in Bratislava, Mlynsk\u00e1 dolina, Ilkovi\u010dova 6, 842 15 Bratislava, Slovakia"}]},{"given":"Martin","family":"Saksa","sequence":"additional","affiliation":[{"name":"National Agriculture and Food Centre, Soil Science and Conservation Research Institute, Tren\u010dianska 55, 821 09 Bratislava, Slovakia"}]},{"given":"Miroslav","family":"Ko\u017euch","sequence":"additional","affiliation":[{"name":"Department of Cartography, Geoinformatics and Remote Sensing, Faculty of Natural Sciences, Comenius University in Bratislava, Mlynsk\u00e1 dolina, Ilkovi\u010dova 6, 842 15 Bratislava, Slovakia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0075-4991","authenticated-orcid":false,"given":"Michal","family":"Gallay","sequence":"additional","affiliation":[{"name":"Institute of Geography, Faculty of Science, Pavol Jozef \u0160af\u00e1rik University in Ko\u0161ice, Jesenn\u00e1 5, 040 01 Ko\u0161ice, Slovakia"}]},{"given":"J\u00e1n","family":"Ka\u0148uk","sequence":"additional","affiliation":[{"name":"Institute of Geography, Faculty of Science, Pavol Jozef \u0160af\u00e1rik University in Ko\u0161ice, Jesenn\u00e1 5, 040 01 Ko\u0161ice, Slovakia"}]},{"given":"Vladim\u00edr","family":"P\u00ed\u0161","sequence":"additional","affiliation":[{"name":"National Agriculture and Food Centre, Soil Science and Conservation Research Institute, Tren\u010dianska 55, 821 09 Bratislava, Slovakia"}]},{"given":"Veronika","family":"Or\u0161ulov\u00e1","sequence":"additional","affiliation":[{"name":"Department of Physical Geography and Geoecology, Faculty of Natural Sciences, Comenius University in Bratislava, Mlynsk\u00e1 dolina, Ilkovi\u010dova 6, 842 15 Bratislava, Slovakia"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"16","DOI":"10.1016\/j.earscirev.2013.08.014","article-title":"Predicting soil erosion and sediment yield at regional scales: Where do we stand?","volume":"127","author":"Posen","year":"2013","journal-title":"Earth Sci.
