Beschreibung

Der &&& Operator gibt TRUE zurück, wenn die n-D bounding box der Geometrie A die n-D bounding box der Geometrie B schneidet.

	Dieser Operand benützt jeden Index, der für die Geometrie zur Verfügung stellt.

Verfügbarkeit: 2.0.0

This method supports Circular Strings and Curves.

This function supports Polyhedral surfaces.

This function supports Triangles and Triangulated Irregular Network Surfaces (TIN).

This function supports 3d and will not drop the z-index.

Beispiele: 3D LineStrings

SELECT tbl1.column1, tbl2.column1, tbl1.column2 &&& tbl2.column2 AS overlaps_3d,
                                    tbl1.column2 && tbl2.column2 AS overlaps_2d
FROM ( VALUES
        (1, 'LINESTRING Z(0 0 1, 3 3 2)'::geometry),
        (2, 'LINESTRING Z(1 2 0, 0 5 -1)'::geometry)) AS tbl1,
( VALUES
        (3, 'LINESTRING Z(1 2 1, 4 6 1)'::geometry)) AS tbl2;
