유럽 우주국 (ESA) WorldCereal 분류 시스템은 특정 성장기가 끝난 후 한 달 이내에 제품을 생성하는 것을 목표로 합니다. 전 세계의 성장기는 역동적이므로 프로젝트 내에서 생성된 전 세계 작물 일정을 기반으로 농업 생태 지역 (AEZ)으로 전 세계를 계층화했습니다[1]. 이 데이터 세트의 기능 모음에는 WorldCereal 제품이 생성된 106개의 AEZ가 포함되어 있습니다. 각 AEZ에는 시즌 시작 (SOS) 및 시즌 종료 (EOS)에 따라 설명된 고유한 작물 달력이 있습니다. SOS와 EOS는 연중 일 (DOY)로 표시됩니다. AEZ 계층화 및 후속 WorldCereal 제품 생성에 관한 자세한 내용은 [2]에 설명되어 있습니다.
AEZ 속성:
aez_id: 각 AEZ의 고유 ID입니다. 이 ID를 기반으로 WorldCereal 제품을 필터링할 수 있습니다.
aez_groupid: 그룹 ID는 작물 달력 유사성을 기반으로 여러 고유한 AEZ를 하나의 그룹으로 결합합니다.
tc-annual_sos: tc-annual 시즌의 SOS (DOY)
tc-annual_eos: tc-annual 시즌의 EOS (DOY)
tc-wintercereals_sos: tc-wintercereals 시즌의 SOS (DOY)
tc-wintercereals_eos: tc-wintercereals 시즌의 종료일 (DOY)
tc-springcereals_sos: tc-springcereals 시즌의 SOS (DOY)
tc-springcereals_eos: tc-springcereals 시즌의 EOS (DOY)
tc-maize-main_sos: tc-maize-main 시즌의 SOS (DOY)
tc-maize-main_eos: tc-maize-main 시즌의 종료일 (DOY)
tc-maize-second_sos: tc-maize-second 시즌의 SOS (DOY)
tc-maize-second_eos: tc-maize-second 시즌의 EOS (DOY)
