strategy::area::geographic

Geographic area calculation.

Description

Geographic area calculation by trapezoidal rule plus integral approximation that gives the ellipsoidal correction

Synopsis

template<typename FormulaPolicy, std::size_t SeriesOrder, typename Spheroid, typename CalculationType>
class strategy::area::geographic
{
  // ...
};

Template parameter(s)

Parameter

Default

Description

typename FormulaPolicy

strategy::andoyer

Formula used to calculate azimuths

std::size_t SeriesOrder

strategy::default_order<FormulaPolicy>::value

The order of approximation of the geodesic integral

typename Spheroid

srs::spheroid<double>

The spheroid 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
