Fourier analysis of temporal NDVI in the Southern African and American continents

    Research output: Book/ReportReportProfessional


    Results of applying Fourier analysis of temporal NDVI in southern Africa and southern America are summarized. The decomposition of complex time series of images in simpler periodic components by Fourier analysis allowed the factors that affect the vegetation cover to be analysed much easier. The project provided the first detailed and quantitative climatology of the response of vegetation cover on the continental scale of southern Africa over a period of ten years. The more detailed studies in Argentina and Zambia gave results of practical relevance to agricultural monitoring. Numeric classification methods are improved by applying performance indices and aspects of the fuzzy-sets :theory.
