[postgis-users] ST_MaxDistance

[George Silva]

Hey guys, weird results here...

Check this:

SELECT ST_MaxDistance(
ST_MakeLine(ST_MakePoint(0,0),ST_MakePoint(1,1)),
 ST_MakeLine(ST_MakePoint(0,0),ST_MakePoint(-1,-1)));
-- 2.82842712474619 (this corresponds to 2x sqrt(2)?)

For me the max distance between these polylines is 2.

Or am I expecting something diferent for this function?

Thanks
