Description
select astext(envelope(GeomFromText('POINT(-104 40)')))
"POLYGON((-104 40,-104 40,-104 40,-104 40,-104 40))"
This polygon is invalid.
According to Martin:
- This does look like a bug, or at least a porting problem in GEOS. In JTS, the envelope of a Point is itself a Point. This means that the return value is always a valid geometry, and thus can be safely used in further operations.
