La suite de produits WorldCereal 10 m 2021 de l'Agence spatiale européenne (ESA) se compose de cartes annuelles et saisonnières des cultures à l'échelle mondiale, ainsi que de leur niveau de confiance associé.
Elles ont été générées dans le cadre du projet ESA-WorldCereal. Vous trouverez plus d'informations sur le contenu de ces produits et la méthodologie utilisée pour les générer dans [1].
Cette collection contient jusqu'à 106 images de zones agro-écologiques (ZAE) pour chaque produit. Elles ont toutes été traitées en fonction de leur propre saisonnalité régionale et doivent être considérées comme des produits indépendants. Ces saisons sont décrites dans la liste ci-dessous et ont été développées dans [2] dans le cadre du projet. Notez que les céréales décrites par WorldCereal incluent le blé, l'orge et le seigle, qui appartiennent à la tribu des Triticeae.
Description des saisons WorldCereal :
tc-annual : cycle d'un an défini dans une ZAE à la fin de la dernière saison de croissance considérée
tc-wintercereals : principale saison des céréales définie dans une ZAE
tc-springcereals : saison facultative des céréales de printemps, définie uniquement dans certaines ZAE
tc-maize-main : principale saison du maïs définie dans une ZAE
tc-maize-second : deuxième saison de maïs facultative, définie uniquement dans certaines ZAE
Voici les produits disponibles dans cette collection :
temporarycrops
Maize
wintercereals
springcereals
irrigation
Chaque produit (image) est associé à une classification binaire (0 ou 100) et à une bande de confiance (0 à 100). Notez que les AEZ pour lesquelles aucun produit d'irrigation n'est disponible n'ont pas été traitées en raison de l'indisponibilité des données thermiques Landsat.
La collection doit être filtrée à l'aide d'une ou de plusieurs des propriétés d'image suivantes :
aez_id, qui contient l'ID de l'AEZ à laquelle appartient l'image
produit, décrivant le nom du produit WorldCereal de l'image
saison, décrivant la saison pour laquelle l'image est valide.
