20.500.12556/RUL-154138 Improved automatic classification of litho-geomorphological units by using raster image blending, Vipava Valley (SW Slovenia) Automatic landslide classification based on digital elevation models has become a powerful complementary tool to field mapping. Many studies focus on the automatic classification of landslides’ geomorphological features, such as their steep main scarps, but in many cases, the scarps and other morphological features are difficult for algorithms to detect. In this study, we performed an automatic classification of different litho-geomorphological units to differentiate slope mass movements in field maps by using Maximum Likelihood Classification. The classification was based on high-resolution lidar-derived DEM of the Vipava Valley, SW Slovenia. The results show an improvement over previous approaches as we used a blended image (VAT, which included four different raster layers with different weights) along with other common raster layers for morphometric analysis of the surface (e.g., slope, elevation, aspect, TRI, curvature, etc.). The newly created map showed better classification of the five classes we used in the study and recognizes alluvial deposits, carbonate cliffs (including landslide scarps), carbonate plateaus, flysch, and slope deposits better than previous studies. Multivariate statistics recognized the VAT layer as the most important layer with the highest eigenvalues, and when combined with Aspect and Elevation layers, it explained 90% of the total variance. The paper also discusses the correlations between the different layers and which layers are better suited for certain geomorphological surface analyses. slope deposits geomorphometry automatic classification Maximum Likelihood Classification multivariate statistics PCA true false true Angleški jezik Ni določen Članek v reviji 2024-01-26 11:47:25 2024-01-26 11:47:26 2024-01-27 03:58:18 0000-00-00 00:00:00 2023 0 0 19 str. iss. 2, art. 531 Vol. 15 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 55 2072-4292 10.3390/rs15020531 138060547 remotesensing-15-00531.pdf remotesensing-15-00531.pdf 1 C9D776E18C0A9D8A2556CD28FB46E75F 8ec82ba79dfdc61ed237dd8a76998209e0a79227bf984d77c863b90457956e07 0f313390-bc39-11ee-9241-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=180340 https://www.mdpi.com/2072-4292/15/2/531 0 6bb9c7a7-bc38-11ee-9241-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=180339 Naravoslovnotehniška fakulteta 0 0 0
