Remarks
The ST_Intersection function returns a geometry representing the point set intersection of two spatial objects (the set of points that are in both geometries). The result can be a point, line, polygon, or collection, depending on how the inputs intersect. If the geometries do not intersect, an empty geometry is returned. This function is useful for finding overlapping areas, clipping geometries, or spatial overlay operations. OGC-compliant.
