Lidarové dáta pri výskume závrtov na plošinách Kuchynsko-orešanského krasu

Rok, strany: 2020, 371 - 390

The paper presents the usage of LiDAR data as a basemap for spatial analyses in geographical informational systems (GIS) to identify count, depth and perimeter of dolines in the karst area in the Little Carpathian Mountains (Malé Karpaty in Slovak). Specifically, three karst plateaus were subjects of the study: Biela skala, Dlhý vrch and Komberek. The aim of the paper is to provide a GIS comparison of the location and dimensions of dolines identified using LiDAR data and data obtained from fieldwork. Application of the Fill function in ArcMap 10.1 allowed the identification 91% of dolines originally recognized by the field research. However, comparison between depths and perimeters of identified depressions with those in-situ measured, has not provided such a satisfying result, but it gets better by excluding outliers from analysis. The paper should point out possible differences in the results of GIS analysis compared to in-situ measurements and draw attention especially to those who do not have an opportunity to compare the LiDAR-based results with field observations.
