Abstract:V magistrskem delu obravnavamo žledolom, ki je ob koncu januarja in začetku februarja 2014 povzročil gmotno škodo ne le na vegetaciji, temveč tudi na energetski in železniški infrastrukturi. Po dosedanjih ocenah gre za enega izmed najobsežnejših žledolomov na območju Slovenije v zadnjih desetletjih. V raziskavi nas je zanimala prostorska razporeditev sprememb v biomasi bukovih in smrekovih sestojev na z žledom prizadetih območjih, zaznanih s pomočjo satelita Landsat. V raziskavo sta bili zajeti občini Tolmin in Dobrova - Polhov Gradec. Na omenjenih območjih smo primerjali stanje bukovih in smrekovih sestojev pred ledeno ujmo ter po njej. Medtem ko so nam Landsat satelitski posnetki služili kot orodje za determinacijo območij negativnih sprememb v rastlinski biomasi, smo s pomočjo LiDAR podatkov izračunali različne izpeljanke, kot so digitalni model reliefa (DMR), digitalni model krošenj (DMK) in digitalni model površja (DMP). Izračunano gmotno škodo smo finančno ovrednotili na podlagi podatkov povprečnih odkupnih cen lesa, pridobljenih s strani Statističnega urada Republike Slovenije (SURS). Analiza podatkov, izračun izpeljank ter izdelava tematskih kart in grafikonov je potekala s pomočjo programske opreme ArcGIS.

Title:Estimating the spatial dimension of the sleet event in February 2014 on beech and spruce forest stands in municipalities Tolmin and Dobrova - Polhov Gradec by applying remote sensing technology
Abstract:In this master’s thesis we examine the problem of the ice storm, which caused material damage not only on vegetation, but also on energy and railway infrastructures. According to previous estimates, this destructive ice storm was one of the most extensive in Slovenia in recent decades. In the study, we examined the spatial dimension of changes in the biomass of beech and spruce forest stands in affected areas, detectable using the Landsat satellite. The study’s research covers municipalities of Tolmin and Dobrova - Polhov Gradec. While the Landsat satellite imagery was used as a tool for determining areas of negative changes in biomass, various variables such as digital elevation model (DEM) and digital surface model (DSM) were calculated by using the LiDAR data. The material damage was financially evaluated according to the national average purchase prices of wood. The data analysis, the calculation of variables, and the production of thematic maps and charts were carried out using the ArcGIS software.
