Hi,
I need to find the intersection point between two lines,
the first choice is ST_Intersection, but I notice even the
ST_ClosestPoint function.
Testing both:
select ST_AsText(ST_ClosestPoint(ST_GeomFromEWKT('SRID=3003;LINESTRING(4
4, 6 6)'),ST_GeomFromEWKT('SRID=3003;LINESTRING(12 1, 3 5)')));
--> POINT(4.38461538461539 4.38461538461539)
select ST_AsText(ST_Intersection(ST_GeomFromEWKT('SRID=3003;LINESTRING(4
4, 6 6)'),ST_GeomFromEWKT('SRID=3003;LINESTRING(12 1, 3 5)')));
--> POINT(4.38461538461539 4.38461538461539)
They gave the same result.
Supposing the geometry to check are linestrings
there is some difference between the two functions ?
Thx,
Andrea.
