매개 변수
| 이름 | Type | 필수 | 설명 |
|---|---|---|---|
| h3cell | string |
✔️ | geo_point_to_h3cell()에서 계산한 H3 셀 토큰 값입니다. |
반품
H3 셀 인접 항목의 배열입니다. H3 셀이 유효하지 않으면 쿼리에서 null 결과를 생성합니다.
참고 항목
인접 항목이 필요한 경우 geo_h3cell_rings()를 참조하세요.
예제
다음 예제에서는 H3 셀 인접 항목을 계산합니다.
print neighbors = geo_h3cell_neighbors('862a1072fffffff')
출력
| 이웃 |
|---|
| ["862a10727ffffff","862a10707ffffffff","862a1070fffffff","862a10777ffffffff","862a100dfffffff","862a100d7ffffff"] |
다음 예제에서는 인접 항목이 있는 입력 H3 셀의 배열을 계산합니다.
let h3cell = '862a1072fffffff';
print cells = array_concat(pack_array(h3cell), geo_h3cell_neighbors(h3cell))
출력
| 셀 |
|---|
| ["862a1072fffffff","862a10727ffffffff","862a10707ffffffff","862a1070fffffff","862a1077ffffffff","862a100dfffffff","862a100d7ffffff"] |
다음 예제에서는 H3 셀 다각형 GeoJSON 기하 도형 컬렉션을 계산합니다.
let h3cell = '862a1072fffffff';
print cells = array_concat(pack_array(h3cell), geo_h3cell_neighbors(h3cell))
| mv-expand cells to typeof(string)
| project polygons = geo_h3cell_to_polygon(cells)
| summarize arr = make_list(polygons)
| project geojson = bag_pack("type", "Feature","geometry", bag_pack("type", "GeometryCollection", "geometries", arr), "properties", bag_pack("name", "polygons"))
출력
