spherical polygon area about geometry

[awulkiew]

What version of Boost are you using? develop and 1.64 seems to be fine.

My test:

typedef bg::model::point<double, 2, bg::cs::spherical_equatorial<bg::degree> > point;
typedef bg::model::polygon<point> polygon;

polygon poly1, poly2;
bg::read_wkt("POLYGON((0 0,90 0,0 -90,0 0))", poly1);
bg::read_wkt("POLYGON((0 0,0 90,90 0,0 0))", poly2);

double a1 = bg::area(poly1);
double a2 = bg::area(poly2);

I'm getting 1.5707963267948963 in both cases. The same for float coordinate type.

I couldn't reproduce it so I'm going to close this issue. You didn't confirm or deny that the code above works for you so reopen this issue if needed. For now I'll assume that in recent versions of Boost the problem is fixed.
