Hi Mateusz, Barend No worries about the previous post :-) GeographicLib is a set of C++ classes, there is no such dependencies with PROJ4 (from my understanding). I actually asked Barend if you guys had a look to this library because the library can do geodesic computation: http://geographiclib.sourceforge.net/html/geodesic.html <http://geographiclib.sourceforge.net/html/geodesic.html> http://geographiclib.sourceforge.net/html/classGeographicLib_1_1Geodesic.htm... <http://geographiclib.sourceforge.net/html/classGeographicLib_1_1Geodesic.html>However, I am not sure that Boost Geometry is able to perform "geodesic direct / inverse" computation (cf. links before). Any advice on this part? Thank you. Romain On 25 March 2010 03:31, Mateusz Loskot <mateusz@loskot.net> wrote:

Hi Romain,
Nothing related but, have you done any comparison with GeographicLib (
http://geographiclib.sourceforge.net/)? In term of performance and accuracy for geodesic computation?
I know this library but didn't test these aspects. All our projections are converted from proj4 to C++, and by this conversion alone they are slightly faster. It is indeed interesting to see if there are differences with this library.
AFAIS, Geographiclib is not a standalone library but it uses PROJ.4
We don't have yet official performance tests for projections in the suite
Mateusz pointed to.
I have to confess I replied to Romain's post assuming, incorrectly, Geographiclib is a yet another geometry library.
Sorry for confusing.
