sdo_geom.sdo_area gives negative areas

by =?ISO-8859-15?Q?Jens_M=FCller?= <usenet-11-2007@[EMAIL PROTECTED] > May 8, 2008 at 03:46 PM

Hi,

I used the sdo_geom.sdo_area function on some polygons in my database.

The result is a negative number, the absolute value seems to be right.

At a first glance, I did not find anything on this in the docs. Is this 
maybe due to a wrong direction (clockwise vs. counter-clockwise) of the 
points?

If so, is this "bad" apart from the negative area values?
