Description

Calculates area on the surface of a sphere using the trapezoidal rule

Synopsis

template<typename RadiusTypeOrSphere, typename CalculationType>
class strategy::area::spherical
{
  // ...
};

Template parameter(s)

Description

typename RadiusTypeOrSphere

double

numeric type for radius (of sphere, earth) or sphere model

typename CalculationType

void

numeric type for calculation (e.g. high precision); if void then it is extracted automatically from the coordinate type and (if necessary) promoted to floating point
