## Name

&<| — Returns `TRUE` if A's bounding box overlaps or is below B's.

## Synopsis

`boolean &<|(` geometry A , geometry B `)`;

## Description

The `&<|` operator returns `TRUE` if the bounding box of geometry A overlaps or is below of the bounding box of geometry B, or more accurately, overlaps or is NOT above the bounding box of geometry B.

This method supports Circular Strings and Curves

This function supports Polyhedral surfaces.

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

## Examples

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

     column1 | column1 | overbelow
    ---------+---------+-----------
    	   1 |       2 | f
    	   1 |       3 | t
    	   1 |       4 | t
    (3 rows)
