20.500.12556/DiRROS-19779 Using lidar data to analyse sinkhole characteristics relevant for understory vegetation under forest cover-case study of a high karst area in the Dinaric mountains In this article, we investigate the potential for detection and characterization of sinkholes under dense forest cover by using airborne laser scanning data. Laser pulse returns from the ground provide important data for the estimation of digital elevation model (DEM), which can be used for further processing. The main objectives of this study were to map and determine the geomorphometric characteristics of a large number of sinkholes and to investigate the correlations between geomorphology and vegetation in areas with such characteristics. The selected study area has very low anthropogenic influences and is particularly suitable for studying undisturbed karst sinkholes. The information extracted from this study regarding the shapes and depths of sinkholes show significant directionality for both orientation of sinkholes and their distribution over the area. Furthermore, significant differences in vegetation diversity and composition occur inside and outside the sinkholes, which indicates their presence has important ecological impacts. sinkholes geomorphology vegetation lidar geomorfologija gozdna vegetacija kras vrtače true false true Angleški jezik Slovenski jezik Neznano 2024-07-25 04:12:32 2024-07-26 13:32:08 2024-07-27 04:00:54 0000-00-00 00:00:00 2015 0 0 Nasl. z nasl. zaslona; Opis vira z dne 26. 3. 2015; Članek v pdf obsega 19 str.; Soavtorji: Irena Bertoncelj, Francesco Pirotti, Igor Dakskobler, Lado Kutnar; iss. 3 Vol. 10 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2015-03-20 574 1932-6203 10.1371/journal.pone.0122070 3397199 http://dx.doi.org/10.1371/journal.pone.0122070 1 97708f5b-4a1a-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27400 RAZ_Kobal_Milan_2015.pdf RAZ_Kobal_Milan_2015.pdf 1 34DC6EA26E1344E974FD95B5D3A63CA0 4c4a46fe57bf302ef60829277759559d07279f25cd07583202a07d8b19dc8ddf 374d3853-4b32-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27630 Nacionalni inštitut za biologijo Gozdarski inštitut Slovenije 0 0 0
