Hello,
In the BoostCon paper you make a benchmark with, among others, the Boolean operations of CGAL, the Computational Geometry Algorithms Library. Which of the following two packages did you use: - http://www.cgal.org/Manual/beta/doc_html/cgal_manual/Boolean_set_operations_...
This one.
My friend Barend Gehrels [Barend.Gehrels@geodan.nl] also has several countires for the geographic database that CGAL fails on. You might be able to get them from him quite easily.
I confirm that I've done a benchmark using several geometry libraries, including Boost.Polygon, CGAL and ggl. It is not yet published. But I will give some feedback soon, also in the scope of this Formal Review. I encountered some counties not being accepted by CGAL, but lateron discovered that some (at least one county) was indeed invalid. So I have to recheck what is the problem there and in the other cases, the shapefile or the library. I will come back to this.
I would be glad to check your claim that CGAL failed on one of your data sets. Are your benchmark testdrivers for the various libs under the boost svn, or can you post them, or send them in a private mail.
Regards, Barend
