I tried your polygons and the intersection seems to work.

Please checkout the attached program, and let us know if you get a similar output. The output that I get is:

MULTIPOLYGON(((75 150,250 150,250 75,75 75,75 150)))

Best,

Hi all,

I have a question regarding the intersection of ring concepts using Boost.Geometry. I currently have two overlapping rectangles defined by the following WKTs:

POLYGON((75 75,75 175,275 175,275 75,75 75))POLYGON((50 50,50 150,250 150,250 50,50 50))

When I perform the intersection of these rectangles, I get the intersection points:

POLYGON((75 150,250 75))

The intersection points do not allow me to compute the area correctly after the intersection. Is there way to get a fully valid ring/polygon out of intersection, so that the area will be equal to the overlapping region?

Thanks!Will
