20.500.12556/RUL-103599 Opazovanje suše s satelitskimi posnetki – uporabnost indeksov stanja vegetacije in standardiziranega padavinskega indeksa magistrsko delo Observation of drought with satellite imagery – usefulness of Vegetation Condition Index and Standardized Precipitation Index master thesis Namen magistrske naloge je bil preučiti uporabnost indeksa stanja vegetacije in standardiziranega padavinskega indeksa za opazovanje suše s satelitskimi posnetki. Uporabnost indeksov smo preverjali na območju meteoroloških postaj Lendava, Ljubljana Bežigrad, Novo mesto in Postojna, na podlagi izbranih točk, za katere imamo podatke o dejanski rabi tal (listnati gozd, mešana raba, polja, travniki, vinogradi, iglasti gozd in nasadi). Za izbrane točke smo pridobili podatke o časovnih serijah produkta MODIS MOD13Q1 in izračunali indeks stanja vegetacije. Izračunane vrednosti standardiziranega padavinskega indeksa (SPI1, SPI2, SPI3, SPI4, SPI6, SPI9, SPI12) smo primerjali z indeksom stanja vegetacije. Primerjavo smo naredili z namenom, da bi ugotovili kako sta indeksa med seboj koreliranega oz. s tem bi pridobili podatek, po kolikšnem času se vegetacija odzove na primanjkljaj padavin. Na podlagi rezultatov smo komentirali uporabnost indeksov in podali bistvene ugotovitve. The purpose of the Master’s Thesis was to study the usefulness of Vegetation Condition Index and Standardized Precipitation Index, for observing droughts with satellite imagery. The usefulness of the indices was checked in the area of meteorological stations Lendava, Ljubljana Bežigrad, Novo mesto and Postojna, for which we have information on actual land use (deciduous forest, mixed land-use, fields, meadows, vineyards, coniferous forest and plantations). For selected points, we obtained data on time series MODIS MOD13Q1 and calculated Vegetation Condition Index. The calculated values of the Standardized Precipitation Index (SPI1, SPI2, SPI3, SPI4, SPI6, SPI9, SPI12) we compared with Vegetation Condition Index. A comparison was made in the order to find out, how the indices were correlated with each other. This would provide information on the extent, to which the vegetation response to the precipitation deficit. Based on the results, we commented on the usefulness of the indices and made important findings. normirani diferencialni vegetacijski indeks standardizirani padavinski indeks stanje vegetacije suša korelacija Normalized Difference Vegetation Index Standardized Precipitation Index Vegetation Condition Index drought correlation true false false [A.
