ST_Disjoint

Returns true if geomA is disjoint from geomB.

Usage

boolean ST_Disjoint(geomA: geometry, geomB: geometry)

Arguments

• geomA (geometry): Input geometry
• geomB (geometry): Input geometry

Description

Returns true if the two geometries do not share any points. This is the inverse of ST_Intersects.

Examples

SELECT ST_Disjoint(
    ST_Point(0.25, 0.25),
    ST_GeomFromText('POLYGON ((0 0, 1 0, 0 1, 0 0))')
) AS val;
