20.500.12556/RUL-168894 Prikaz svetlobnega onesnaženja Slovenije s kartami pojavnosti magistrsko delo Presentation of light pollution in Slovenia with heatmaps master thesis Svetlobno onesnaženje predstavlja resen globalni problem, ki negativno vpliva na zdravje ljudi, okolje in živali ter hkrati povzroča nepotrebno energetsko porabo. V magistrski nalogi smo analizirali onesnaženost večjih mestnih središč v Sloveniji in njeni bližnji okolici. Za šest območij (Ljubljana, Maribor, Celje, Novo mesto, Kranj in Koper s Trstom) smo analizirali letne podatke v obdobju 2013– 2022. Posebno pozornost smo namenili času pandemije koronavirusa leta 2020, tako da smo podatke za mesto Ljubljana primerjali z letoma pred in po pandemiji. Za leto 2022 smo prikazali najnižjo, povprečno in najvišjo raven onesnaženja za celotno državno območje in bližnjo okolico. Uporabili smo satelitske posnetke satelitov S-NPP in NOAA-20, ki smo jih pridobili prek platforme Google Earth Engine. Pri obdelavi posnetkov smo uporabili IDW interpolacijo in metodo KDE ter končne rezultate prikazali s kartami pojavnosti in časovnimi vrstami. Rezultati prikazujejo postopno povečanje svetlobnega onesnaženja, kar je skladno z globalnimi trendi. Podobno smo ugotovili tudi za čas pandemije, saj so bile takratne vrednosti svetlobnega onesnaženja mesta Ljubljana nižje kot v letu prej in po tem. Light pollution is a serious global issue, adversely impacting human health, the environment, and wildlife, while also leading to unnecessary energy consumption. In this master's thesis the pollution levels of major urban centers in Slovenia and its surrounding areas were examined. Annual data from the period 2013–2022 were analyzed for six areas (Ljubljana, Maribor, Celje, Novo mesto, Kranj, and Koper with Trieste). Special attention was given to the period of coronavirus pandemic in 2020, by comparing the data, for the city of Ljubljana, with those from the years before and after the pandemic. For 2022, the lowest, average, and highest levels of pollution were presented for the entire national territory and its surroundings. Satellite images from the S-NPP and NOAA-20 satellites were utilized, obtained through the Google Earth Engine platform. Image processing involved IDW interpolation and the KDE method, with the final results presented through Heat maps and Time series. The results show a gradual increase in light pollution, consistent with global trends. A similar conclusion was made regarding the pandemic, during which light pollution levels in Ljubljana were lower compared to the year preceding and following that period. magistrska dela gradbeništvo svetlobno onesnaženje karte pojavnosti časovne vrste NOAA VIIRS posnetki google earth engine večja slovenska mesta master thesis civil engineering light pollution heat map time series NOAA VIIRS Data google earth engine major slovenian cities true false false [J.
