Пакет продуктов WorldCereal 10 м 2021 Европейского космического агентства (ESA) включает в себя карты годовых и сезонных урожаев в глобальном масштабе и соответствующие показатели достоверности. Они были созданы в рамках проекта ESA-WorldCereal . Более подробная информация о содержании этих продуктов и методологии их создания описана в [1].
Эта коллекция содержит до 106 изображений агроэкологических зон (AEZ) для каждого продукта. Все они были обработаны с учётом их региональной сезонности и должны рассматриваться как независимые продукты. Эти сезоны описаны в списке ниже и были разработаны в [2] в рамках проекта. Обратите внимание, что злаки, описанные WorldCereal, включают пшеницу, ячмень и рожь, относящиеся к трибе Triticeae .
Описание сезонов WorldCereal:
tc-annual: однолетний цикл, определяемый в AEZ к концу последнего рассматриваемого вегетационного периода
tc-wintercereals: основной сезон зерновых культур, определенный в AEZ
tc-springcereals: необязательный сезон весенних злаков, определяется только в некоторых AEZ
tc-maize-main: основной сезон кукурузы, определенный в AEZ
tc-maize-second: необязательный второй сезон кукурузы, определяется только в некоторых AEZ
В этой коллекции представлены следующие продукты:
временные культуры
кукуруза
озимые злаки
яровые злаки
орошение
Каждый продукт (изображение) имеет бинарную классификацию (0 или 100) и доверительный интервал (0–100). Обратите внимание, что зоны AEZ, для которых нет данных об орошении, не были обработаны из-за отсутствия тепловых данных Landsat.
Коллекцию следует фильтровать с использованием одного или нескольких из следующих свойств изображения:
aez_id, содержащий идентификатор AEZ, к которому принадлежит изображение
продукт, описывающий название продукта WorldCereal на изображении
сезон, описывающий сезон, для которого относится изображение.
