Name

st_within — Returns true if all points of a given geometry g1 are in another geometry g2.

Synopsis

st_within ( in g1 any ,
in g2 any ,
in prec double precision );

Description

Returns true if all points of g1 are in g2. If prec is supplied, this is a tolerance for the matching in units of linear distance appropriate to the srid. Both geometries should have the same srid.

Parameters

g1

The first geometry.

g2

The second geometry.

prec

A tolerance for the matching in units of linear distance appropriate to the srid. Default is 0.

Return Types

Returns int.
