We involved the original bands, spectral indices and principal components (PCs) of a principal component analysis (PCA) as input data, and performed random forest (RF) and support vector machine (SVM) classification with water, saturated soil and non-water categories. The aim was to compare the efficiency of the results based on various input data. Original bands provided 93% overall accuracy (OA) and bands 4-5-7 were the most informative in this analysis. Except for MNDWI (modified normalized differenced water index, with 98% OA), the performance of all water indices was between 60 and 70% (OA). The PCA-based approach conducted on the original bands resulted in the most accurate identification of all classes (with only 1% error in the case of water bodies). We therefore show that both water bodies and saturated soils can be identified successfully using this approach.}, keywords = {Multivariate Analysis; remote sensing; principal component analysis; SPECTRAL INDEX; Landsat; classification uncertainty analysis}, year = {2018}, eissn = {2150-3435}, pages = {269-284}, orcid-numbers = {Bíró, Tibor/0000-0002-5553-9850; Szabó, Szilárd/0000-0002-2670-7384} } @article{MTMT:3312205, title = {A 300-year record of sedimentation in a small tilled catena in Hungary based on δ 13 C, δ 15 N, and C/N distribution}, url = {https://m2.mtmt.hu/api/publication/3312205}, author = {Jakab, Gergely Imre and Hegyi, I and Fullen, M and Szabó, Judit Alexandra and Zacháry, Dóra and Szalai, Zoltán}, doi = {10.1007/s11368-017-1908-9}, journal-iso = {J SOIL SEDIMENT}, journal = {JOURNAL OF SOILS AND SEDIMENTS}, volume = {18}, unique-id = {3312205}, issn = {1439-0108}, keywords = {DYNAMICS; PLANT; Nitrogen; soil erosion; FRACTIONS; Sedimentation; SOIL ORGANIC-MATTER; WATER EROSION; C-13 ABUNDANCE; CARBON REDISTRIBUTION; SOUTHERN CHINA; N-15 NATURAL-ABUNDANCE; delta N-15; delta C-13; soil organic carbon}, year = {2018}, eissn = {1614-7480}, pages = {1767-1779}, orcid-numbers = {Jakab, Gergely Imre/0000-0001-5424-1983; Szalai, Zoltán/0000-0001-5267-411X} } @article{MTMT:3098840, title = {Redistribution of soil organic carbon triggered by erosion at field scale under subhumid climate, Hungary}, url = {https://m2.mtmt.hu/api/publication/3098840}, author = {Szalai, Zoltán and Szabó, Judit Alexandra and Kovács, József and Mészáros, Erzsébet and Albert, Gáspár and Centeri, Csaba and Keller, Boglárka and Madarász, Balázs and Zacháry, Dóra and Jakab, Gergely Imre}, doi = {10.1016/S1002-0160(15)60074-1}, journal-iso = {PEDOSPHERE}, journal = {PEDOSPHERE}, volume = {26}, unique-id = {3098840}, issn = {1002-0160}, year = {2016}, eissn = {2210-5107}, pages = {652-665}, orcid-numbers = {Szalai, Zoltán/0000-0001-5267-411X; Kovács, József/0000-0002-6797-2504; Albert, Gáspár/0000-0002-1723-8328; Centeri, Csaba/0000-0001-6590-4850; Jakab, Gergely Imre/0000-0001-5424-1983} } @article{MTMT:2886707, title = {Spatial and temporal heterogeneity of runoff and soil loss dynamics under simulated rainfall}, url = {https://m2.mtmt.hu/api/publication/2886707}, author = {Szabó, Judit Alexandra and Jakab, Gergely Imre and Keller, Boglárka}, doi = {10.15201/hungeobull.64.1.3}, journal-iso = {HUNG GEOGR BULL (2009-)}, journal = {HUNGARIAN GEOGRAPHICAL BULLETIN (2009-)}, volume = {64}, unique-id = {2886707}, issn = {2064-5031}, year = {2015}, eissn = {2064-5147}, pages = {25-34}, orcid-numbers = {Jakab, Gergely Imre/0000-0001-5424-1983} } @article{MTMT:2723923, title = {Soil and vegetation transformation in abandoned vineyards of the Tokaj Nagy-Hill}, url = {https://m2.mtmt.hu/api/publication/2723923}, author = {Novák, Tibor József and Incze, József and Spohn, M and Glina, B and Giani, L}, doi = {10.1016/j.catena.2014.07.017}, journal-iso = {CATENA}, journal = {CATENA}, volume = {123}, unique-id = {2723923}, issn = {0341-8162}, year = {2014}, eissn = {1872-6887}, pages = {88-98}, orcid-numbers = {Novák, Tibor József/0000-0002-5514-9035} }
