Description

The && operator returns TRUE if the 2D bounding box of geometry A intersects the 2D bounding box of geometry B.

	This operand will make use of any indexes that may be available on the geometries.

Enhanced: 2.0.0 support for Polyhedral surfaces was introduced.

Availability: 1.5.0 support for geography was introduced.

This method supports Circular Strings and Curves.

This function supports Polyhedral surfaces.

Examples

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

 column1 | column1 | overlaps
---------+---------+----------
       1 |       3 | t
       2 |       3 | f
