ee.FeatureCollection.distinct
컬렉션을 사용해 정리하기
내 환경설정을 기준으로 콘텐츠를 저장하고 분류하세요.
컬렉션에서 중복 항목을 삭제합니다. 중복은 선택한 속성의 직렬화된 형태에 대한 강력한 해시를 사용하여 결정됩니다.
| 사용 | 반환 값 |
|---|
FeatureCollection.distinct(properties) | FeatureCollection |
| 인수 | 유형 | 세부정보 |
|---|
다음과 같은 경우: collection | FeatureCollection | 객체를 선택할 입력 컬렉션입니다. |
properties | 객체 | 비교에 사용할 속성 이름 또는 속성 이름 목록입니다. '.geo' 속성을 포함하여 객체 지오메트리를 비교할 수 있습니다. |
예
코드 편집기 (JavaScript)
// FeatureCollection of power plants in Belgium.
var fc = ee.FeatureCollection('WRI/GPPD/power_plants')
.filter('country_lg == "Belgium"');
print('FeatureCollection of power plants in Belgium', fc);
// Remove duplicate features according to property values.
print('Distinct based on a single property', fc.distinct('fuel1'));
print('Distinct based on two properties', fc.distinct(['fuel1', 'source']));
print('Distinct based on geometry', fc.distinct('.geo'));
