System klasyfikacji European Space Agency (ESA) WorldCereal
ma na celu generowanie produktów w ciągu miesiąca od zakończenia danego sezonu wegetacyjnego. Ze względu na dynamiczny charakter tych okresów wegetacyjnych na całym świecie przeprowadzono globalną stratyfikację na strefy agroekologiczne (AEZ) na podstawie globalnych kalendarzy upraw utworzonych w ramach projektu [1]. Zbiór obiektów w tym zbiorze danych
zawiera 106 stref AEZ, dla których wygenerowano produkty WorldCereal. Każda strefa AEZ ma unikalne kalendarze upraw, które są opisywane na podstawie początku sezonu (SOS) i końca sezonu (EOS). SOS i EOS są podawane w dniach roku (DOY). Więcej informacji o podziale na strefy AEZ i generowaniu produktu WorldCereal znajdziesz w [2].
Właściwości AEZ:
aez_id: unikalny identyfikator każdej strefy AEZ. Produkty WorldCereal można filtrować na podstawie tego identyfikatora.
aez_groupid: identyfikator grupy łączy kilka unikalnych stref AEZ w grupę na podstawie podobieństwa kalendarza upraw.
tc-annual_sos: SOS w sezonie tc-annual (DOY)
tc-annual_eos: koniec sezonu tc-annual (dzień roku)
tc-wintercereals_sos: SOS w sezonie tc-wintercereals (dzień roku)
tc-wintercereals_eos: koniec sezonu tc-wintercereals (dzień roku)
tc-springcereals_sos: SOS of the tc-springcereals season (DOY)
tc-springcereals_eos: koniec sezonu tc-springcereals (dzień roku)
tc-maize-main_sos: SOS w głównym sezonie uprawy kukurydzy (DOY)
tc-maize-main_eos: EOS głównego sezonu kukurydzy (dzień roku)
tc-maize-second_sos: SOS w drugim sezonie uprawy kukurydzy (dzień roku)
tc-maize-second_eos: koniec sezonu tc-maize-second (dzień roku)
Brakujące wartości SOS i EOS wskazują na brak odpowiedniego sezonu wegetacyjnego w danej strefie agroekologicznej.
