7030	distance of point to linestring with cs::spherical_equatorial gives wrong result	anonymous	Barend Gehrels	"The following code produces some strange results:

typedef cs::spherical_equatorial< boost::geometry::degree > cs_type;
typedef model::point< double , 2, cs_type > point_type;
typedef model::linestring< point_type > linestring_type;

point_type p( 1.0 , 1.0 );
linestring_type l;
l.push_back( point_type( 0.0 , 2.0 ) );
l.push_back( point_type( 2.0 , 2.0 ) );
l.push_back( point_type( 4.0 , 2.0 ) );

cout << ""Distance : "" << boost::geometry::distance( p , l ) << endl;

for( size_t i=1 ; i<l.size() ; ++i )
{
    linestring_type l_tmp;
    l_tmp.push_back( l[i-1] );
    l_tmp.push_back( l[i] );
    cout << ""Point distance : "" << boost::geometry::distance( p , l_tmp
) << endl;
}



The output is

Distance : 0.0174373

Point distance : 0.0174586
Point distance : 0.0174373

The distance to the second segment can not be smaller than that to the first one. If the the coordinate system is changed to cartesian coordinates everything works as expected.
