8.10.1. Bounding Box Operators

Name

@(box2df,geometry) — Returns TRUE if a 2D float precision bounding box (BOX2DF) is contained into a geometry’s 2D bounding box.

Synopsis

boolean +`*`@`*`(` box2df `+A , geometry B );

Description

The @ operator returns TRUE if the 2D bounding box A is contained into the B geometry’s 2D bounding box, using float precision. This means that if B is a (double precision) box2d, it will be internally converted to a float precision 2D bounding box (BOX2DF)

This operand is intended to be used internally by BRIN indexes, more than by users.

Availability: 2.3.0 support for Block Range INdexes (BRIN) was introduced. Requires PostgreSQL 9.5+.

check This method supports Circular Strings and Curves

check This function supports Polyhedral surfaces.

Examples

SELECT ST_MakeBox2D(ST_Point(2,2), ST_Point(3,3)) @ ST_Buffer(ST_GeomFromText('POINT(1 1)'), 10) AS is_contained;
