20.500.12556/RUL-130759 Uporaba satelitskih posnetkov Landsat in Sentinel za preučevanje širjenja pozidanih površin v Mestni občini Ljubljana Use of Landsat and Sentinel satellite images for studying the spread of built-up areas in the Municipality of Ljubljana V diplomski nalogi smo zaznavali pozidane površine v Mestni občini Ljubljana s tremi različnimi sateliti med leti 2000, 2013 in 2020. Uporabili smo tri različne metode: nadzorovano klasifikacijo, spektralne indekse z mejo po Otsujevi metodi in spektralne indekse z ročno nastavljeno mejo. Namen naloge je bil torej ugotoviti, katera izmed treh preprostih metod daljinskega zaznavanja daje najboljše rezultate. Ugotovili smo, da je to nadzorovana klasifikacije, prav tako pa sta tudi Normalized Difference Vegetation Index (NDVI) in Built-up Index (BU) z ročno nastavljeno mejo prikazala dokaj dober rezultat. Najslabše rezultate je dala metoda spektralnih indeksov z mejo po Ostujevi metodi. Hkrati smo potrdili izkušnje avtorjev, ki so se ukvarjali s podobnimi tematikami, da težko primerjamo satelitske slike večih satelitov, zaradi različne kakovosti (Sabo, Corbane, Ferri, 2017). In this paper we detected built-up areas in the Municipality of Ljubljana with three different satellites between years 2000, 2013 and 2020. We used three different methods: supervised classification, spectral indices with a limit according to the Otsu method and spectral indices with a manually set limit. The purpose of the task was to determine which method gives the best results. We found that it is a supervised classification, and also Normalized Difference Vegetation Index and Built-up Index with manually set limit which showed a fairly good result. The worst results were obtained by the method of spectral indices with a limit according to the Ostuje method. At the same time, we agree with other authors which have dealt with similar topics that it is difficult to compare satellite images of multiple satellites, due to different quality (Sabo, Corbane, Ferri, 2017). pozidane površine daljinsko zaznavanje Mestna občina Ljubljana satelitski posnetki klasifikacija Built-up areas remote sensing Municipality of Ljubljana satellite images classification true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2021-09-17 07:45:08 2021-09-17 07:45:10 2022-09-09 04:17:53 0000-00-00 00:00:00 2021 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 481932 12089.pdf 12089.pdf 1 F70346BEF7586737BCC0BE4A48001C4E 31feb66af209e3e6b819be41f6cbb20a0136a85fa200082ef71ee5f06ba6d9e6 28c85358-177a-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=147909 Filozofska fakulteta 0 0 0
