Hi,

I am trying to work with boost 1.57 and also I've got the geometry.extensions.gis from the develop branch. I am using geographic cs. Looking at extensions\gis\geographic\strategies\andoyer.hpp I think there is a problem with one of the constructors:

    explicit inline andoyer(RadiusType f)
        : m_ellipsoid(f)
    {}

I think should be:

    explicit inline andoyer(RadiusType f)
        : m_ellipsoid(f, f)
    {}

(note the second radius passed to m_ellipsoid). Otherwise it chooses the incorrect constructor for the ellipsoid and distances are incorrect.

Sorry for posting it in the groups - I am not sure what the proper way to submit a patch is.

Best,

Branimir
