유럽우주기구 (ESA) WorldCereal 10m 2021 제품군은 전 세계 규모의 연간 및 계절별 작물 지도와 관련 신뢰도로 구성됩니다.
이러한 데이터는 ESA-WorldCereal 프로젝트의 일부로 생성되었습니다. 이러한 제품의 콘텐츠와 이를 생성하는 데 사용된 방법론에 관한 자세한 내용은 [1]에 설명되어 있습니다.
이 컬렉션에는 각 제품에 대해 최대 106개의 농업 생태 지역 (AEZ) 이미지가 포함되어 있으며, 이 이미지는 모두 자체 지역별 계절성을 고려하여 처리되었으며 독립적인 제품으로 간주해야 합니다. 이러한 시즌은 아래 목록에 설명되어 있으며 프로젝트의 일환으로 [2] 에서 개발되었습니다. WorldCereal에서 설명하는 곡물에는 Triticeae 부족에 속하는 밀, 보리, 호밀이 포함됩니다.
WorldCereal 시즌 설명:
tc-annual: 마지막으로 고려된 성장 시즌이 끝날 때까지 AEZ에서 정의되는 1년 주기
tc-wintercereals: AEZ에 정의된 주요 곡물 시즌
tc-springcereals: 선택적 봄 곡물 시즌, 특정 AEZ에서만 정의됨
tc-maize-main: AEZ에 정의된 주요 옥수수 시즌
tc-maize-second: 선택적 두 번째 옥수수 시즌, 특정 AEZ에서만 정의됨
이 컬렉션에서 사용할 수 있는 제품은 다음과 같습니다.
temporarycrops
Maize
wintercereals
springcereals
관개
각 제품 (이미지)에는 이진 분류 (0 또는 100)와 신뢰도(0~100) 범위가 있습니다. 관개 제품을 사용할 수 없는 AEZ는 열 Landsat 데이터를 사용할 수 없어 처리되지 않았습니다.
