[postgis-users] Correcting polygon with holes

[Malm Paul]

Hi list,

I have Shape files with polygons that I would like to store in a Postgis
database. The polygons has holes in them.
I've noticed (in the Shape files i'm using) that some holes can be
defined clockwise and others can be defined counter clockwise.

Is there an easy way to redifine the polygons in Postgis, or is the
anyone who has a fast algoritm to descide if it is clockwise or counter
clockwise?

Thanks,
Paul
