Abstract

V diplomski nalogi smo, z analizo satelitskih posnetkov, določili delež zelenih površin na določenem območju. Obravnavana so območja izbranih slovenskih mest in ljubljanskih četrti. Opisana je metoda, s katero lahko določimo mejo mest. Arhiv satelitskih posnetkov je zelo obsežen, dostop do njih pa preprost in brezplačen. Za potrebe naših analiz smo prenesli podatke satelitov Sentinel-2A, Landsat 5 in Landsat 8. Zelenost območij smo določili z izračunom normiranega diferencialnega vegetacijskega indeksa (NDVI). Na podlagi teh rezultatov smo lahko določili, kako močno so zelena slovenska mesta in kakšen je delež zelenih površin v mestu. Izvedli smo tri analize, in sicer primerjavo med šestimi slovenskimi mesti (Ljubljana, Maribor, Celje, Kranj, Novo mesto in Koper), primerjavo med štirimi ljubljanskimi četrtnimi skupnostmi (Center, Bežigrad, Šiška in Moste) ter na koncu še analizo sprememb v zelenosti mesta Ljubljana, v obdobju od leta 1984 do leta 2017. Za vsako analizo so v rezultatih prikazane karte vrednosti NDVI in mej območij ter dodan histogram vrednosti NDVI.

Secondary title: How green are Slovenian cities
Secondary abstract: In the graduation thesis, we have determined the proportion of green areas on a certain area with analysis of satellite images. Reviewed are areas of certain Slovenian cities and quarters of Ljubljana. A method for determining the borders of cities is described. The archive of satellite images is very extensive and access to them is simple and free. For our analysis, we have downloaded the data from satellites Sentinel-2A, Landsat 5 and Landsat 8. We have determined the greenness of surfaces with the calculation of normalized difference vegetation index (NDVI). Based on the results, we could determine how green are the Slovenian cities and what is the proportion of green areas in the city. We performed three analyzes, namely a comparison between six Slovenian cities (Ljubljana, Maribor, Celje, Kranj, Novo mesto and Koper), a comparison between four city quarters of Ljubljana (Center, Bežigrad, Šiška and Moste) and an analysis of changes in greenness of Ljubljana in the period from 1987 to 2017. For each analysis, there are maps with NDVI values and borders of areas in the results. There are also added Histograms of NDVI values.
