#### strategy::line_interpolate::geographic

Interpolate point on a geographic segment.

###### Synopsis

    template<typename FormulaPolicy, typename Spheroid, typename CalculationType>
    class strategy::line_interpolate::geographic
    {
      // ...
    };

###### Template parameter(s)

Parameter | Default | Description
--- | --- | ---
typename FormulaPolicy | strategy::andoyer | The geodesic formulas used internally.
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
