ee.Filter.date
컬렉션을 사용해 정리하기
내 환경설정을 기준으로 콘텐츠를 저장하고 분류하세요.
기간으로 컬렉션을 필터링합니다. 시작과 종료는 날짜, 숫자일 수 있습니다.
(1970-01-01T00:00:00Z 이후의 밀리초로 해석됨) 또는 문자열 (예: '1996-01-01T08:00') 'system:time_start' 속성을 기반으로 합니다.
생성된 필터를 반환합니다.
| 사용 | 반환 값 |
|---|
ee.Filter.date(start, end) | 필터 |
| 인수 | 유형 | 세부정보 |
|---|
start | 날짜|숫자|문자열 | 시작일 (해당 날짜 포함)입니다. |
end | 날짜|숫자|문자열(선택사항) | 종료일 (해당 날짜 제외)입니다. 선택사항입니다. 지정하지 않으면 'start'에서 시작하는 1밀리초 범위가 생성됩니다. |
