ST_Crosses¶

Returns true if A crosses B.

Usage¶

boolean ST_Crosses(geomA: geometry, geomB: geometry)

Arguments¶

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

Description¶

Returns true if the two geometries have some (but not all) interior points in common and the dimension of the intersection is less than that of either input.

Examples¶

SELECT ST_Crosses(
    ST_GeomFromWKT('LINESTRING(0 0, 2 2)'),
    ST_GeomFromWKT('LINESTRING(0 2, 2 0)')
);
