Returns the point-set intersection of the two input geometries as a 2D geometry.
Syntax
st_intersection ( geo1, geo2 )
Arguments
geo1: The firstGEOMETRYvalue.geo2: The secondGEOMETRYvalue.
Returns
A value of type GEOMETRY, representing the point-set intersection of the two input geometries.
The SRID of the returned GEOMETRY value is the common SRID of the input geometries.
The function returns NULL if any of the inputs is NULL.
Error conditions
- If any of the two input geometries is a geometry collection, the function returns ST_INVALID_ARGUMENT.INVALID_TYPE.
- If the two input geometries have different SRID values, the function returns ST_DIFFERENT_SRID_VALUES.
Examples
SQL
-- Returns the intersection of a multipoint and a polygon.
> SELECT st_astext(st_intersection(st_geomfromtext('MULTIPOINT(EMPTY,4 3,5 6,-1 8)'),st_geomfromtext('POLYGON((0 0,10 0,0 10,0 0))')));
POINT(4 3)
-- Returns the intersection of two overlapping polygons.
> SELECT st_astext(st_intersection(st_geomfromtext('POLYGON((0 0,10 0,10 10,0 10,0 0))'),st_geomfromtext('POLYGON((5 5,15 5,15 15,5 15,5 5))')));
POLYGON((5 5,10 5,10 10,5 10,5 5))
