Abstract

An advantageous consequence of the rapid evolution of topographic data acquisition techniques is possibility to define the topography with increasingly higher accuracy. New remote sensing techniques and data processing methods allow to detect microtopographic features of karst phenomena with unprecedented precision. Our aim in this study was to compare the digital terrain models (DTMs) generated from various data sources acquired by different technologies to define dolines in the Hungarian part of the Gömör-Torna karst. An automated method of doline recognition is presented here; the results of this processing technique is compared to that of the classic outlining. We compared the three doline database using geomorphometric tools. Our conclusion is that, however, the classic method is efficient, but the LiDAR DTM-based method is more accurate in detecting and analyzing dolines
