WKB를 도형으로 해석

항목	값
화면 이름	Parse well known binary as geometry
식별자	`parseWellKnownBinaryAsGeometryV1`
지원 실행 방식	Batch, Faster, Streaming
범주	지리공간 (Geospatial)
반환 자료형	`Geometry`

Well-known binary(WKB)를 도형 논리 자료형으로 변환합니다. 잘못된 WKB는 null이 됩니다. WGS84가 아니면 원천 좌표계 식별자를 선택적으로 지정하여 WGS84로 변환합니다.

입력 인자

이름	지정 여부	자료형	의미와 조건
`Expression`	필수	`Expression<Binary>`	유효한 WKB 바이너리입니다.
`Source coordinate system`	선택	`Literal<String>`	WKB가 WGS84가 아닐 때 지정할 선택적 원천 좌표계입니다. `authority:id` 형식이며 UTM 18N의 예는 `EPSG:32618`입니다.
