ee.Geometry.MultiPolygon.withinDistance
컬렉션을 사용해 정리하기
내 환경설정을 기준으로 콘텐츠를 저장하고 분류하세요.
지오메트리가 지정된 거리 내에 있는 경우에만 true를 반환합니다.
사용 | 반환 값 |
---|
MultiPolygon.withinDistance(right, distance, maxError, proj) | 불리언 |
인수 | 유형 | 세부정보 |
---|
다음과 같은 경우: left | 도형 | 연산의 왼쪽 피연산자로 사용되는 지오메트리입니다. |
right | 도형 | 작업의 오른쪽 피연산자로 사용되는 지오메트리입니다. |
distance | 부동 소수점 수 | 거리 기준점입니다. 투영이 지정된 경우 거리는 투영된 좌표계의 단위로 표시되고, 그렇지 않은 경우 미터 단위로 표시됩니다. |
maxError | ErrorMargin, 기본값: null | 필요한 재투영을 실행할 때 허용되는 최대 오류량입니다. |
proj | 예상, 기본값: null | 작업을 실행할 프로젝션입니다. 지정하지 않으면 작업이 구면 좌표계에서 실행되며 선형 거리는 구의 미터 단위입니다. |
