20.500.12556/RUL-150205 Uporaba satelitskih posnetkov in geoinformatike pri spremljanju gibanja volkov diplomska naloga št.: 224/GIG Using satellite imagery and geoinformatics to monitor wolf movements Graduation thesis no.: 224/GIG V diplomski nalogi sem s posnetki satelita Landsat 7, podatki o rabi tal v Sloveniji leta 2011 in 2012, slojem reliefa DMV12,5 in telemetričnimi podatki o pojavljanju volkov v Sloveniji, pridobljenimi v okviru projekta SloWolf naredila prostorske analize. Za pridobitev potrebnih prostorskih analiz sem uporabila podatke gibanja volka z imenom Luka avgusta 2011, septembra 2011, novembra 2011, januarja 2012 in februarja 2012. Vhodni podatek za prikaz gostote pojavljanja so bili telemetrični podatki podani v točkovnem vektorskem sloju. Z njimi sem z vtičnikom Density Analysis v programu QGIS ustvarila prikaze gostote v obliki heksagonov H3. Na teh heksagonih sem nadalje izvedla analize območne statistike. Za vsak heksagon sem izračunala povprečen normaliziran diferencialni vegetacijski indeks NDVI, povprečen naklon in povprečno nadmorsko višino ter večinsko rabo tal. Ustvarila sem prikaze na katerih sem imela v enem heksagonu sočasno predstavljeno gostoto pojavljanja Luka in povprečje indeksa NDVI, naklona, višine terena ali večinsko rabo tal. Analize opravljene v programu QGIS, sem podkrepila z analizami in ustvarjenimi grafikoni v programu Microsoft Excel. Na podlagi dobljenih rezultatov sem ugotovila, da se volkovi na študijskem območju gibljejo po gozdovih z nižjo intenziteto vegetacije (nizkim indeksom NDVI). Glede reliefa raje izberejo položna območja z naklonom med 10° in 20° ter nadmorske višine med 800 m in 1000 m. In this thesis, I conducted spatial analyses using remotely sensed satellite imagery from Landsat 7, land use data for Slovenia from 2011 and 2012, the layer of relief DMV12.5 and telemetry data on wolf occurrences in Slovenia obtained as part of the SloWolf project. For the necessary spatial analyses, I used wolf movement data for the wolf named Luka in August 2011, September 2011, November 2011, January 2012 and February 2012. The input data for the occurrence density plot were telemetry data in a point-vector layer format. With the QGIS plugin Density Analysis, I created density visualisations using H3 hexagons. Further analysis was conducted on these hexagons to examine regional statistics. I calculated the average normalised difference vegetation index (NDVI), the average slope of the hexagon, the average elevation and the predominant land use in each hexagon. I then created visualisations that simultaneously displayed the density of Luka's occurrence and the average NDVI, slope, elevation and land use within each hexagon. The analyses carried out in QGIS were supplemented by analyses and diagrams created using Microsoft Excel. Based on the results obtained, I found that wolves tend to move through forests with lower NDVI values or less vegetated areas. In terms of terrain, they prefer relatively flat areas with 10° and 20° slopes and altitudes between 800 and 1000 metres above sea level. geodezija diplomske naloge GIG daljinsko zaznavanje prostorske analize volkovi gostota območna statistika Landsat 7 QGIS histogrami geodesy graduation thesis remote sensing spatial analyses wolves density regional statistics Landsat 7 QGIS histograms true false false [B.
