[geos-devel] orientation of the rings in a polygon

Hi all,
In the detailed description of the Polygon, it says that "The orientation of the rings in the polygon does not matter"

However, in my particular application, the orientation of the rings does matter.

The polygons I'm using are the result of an intersection in GEOS.

1- Is it possible to get the orientation of a linearRing with GEOS ? How ?

2- Is it possible to set something (i.e a factory) that would guaranty a specific orientation for the rings in the polygons.

Thanks again
Maude Giasson
