ST_Dump¶

Introduction: This function takes a GeometryCollection/Multi Geometry object and returns a set of geometries containing the individual geometries that make up the input geometry. The function is useful for breaking down a GeometryCollection/Multi Geometry into its constituent geometries.

ST_Dump

Format: ST_Dump(geom: geometry)

Return type: Array<Geometry>

SQL example:

SELECT sedona.ST_AsText(geom)
FROM table(sedona.ST_Dump(sedona.ST_GeomFromText('MULTIPOINT ((10 40), (40 30), (20 20), (30 10))')));

Output:

POINT (10 40)
POINT (40 30)
POINT (20 20)
POINT (30 10)
