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. Best regards, -- Mateusz Loskot, http://mateusz.loskot.net
