Detailed Description

An abstraction of a geographic position.

A geographic position holding Latitude and Longitude.

Constructor & Destructor Documentation

GeoPosition()

constexpr rose::GeoPosition::GeoPosition ( double  latitude, double  longitude, bool  rad = false  )

inline

Create a geographic position.

Parameters

latitude	The latitude.
longitude	The longitude.
rad	When true interpret latitude and longitude as degrees, otherwise as radians.

Member Function Documentation

distance()

double rose::GeoPosition::distance ( const GeoPosition &  other ) const

inline

Computer the Great Circle distance between this GeoPosition and another.

Parameters

other

The other GeoPosition.

Returns

The Great Circle distance in Radians.

midpoint() [1/2]

GeoPosition rose::GeoPosition::midpoint ( const GeoPosition &  other, double  distance, double  fraction = 0.5  ) const

inline

Find a mid-point on the Great Circle between this GeoPosition and another.

Parameters

other	The other GeoPosition.
distance	The pre-computed distance between the two positions in Radians.
fraction	The fraction of the distance between the two positions the desired mid-point is from this GeoPosition

Returns

The computed GeoPosition.

midpoint() [2/2]

GeoPosition rose::GeoPosition::midpoint ( const GeoPosition &  other, double  fraction = 0.5  ) const

inline

Find a mid-point on the Great Circle between this GeoPosition and another.

Parameters

other	The other GeoPosition.
fraction	The fraction of the distance between the two positions the desired mid-point is from this GeoPosition

Returns

The computed GeoPosition.

toDegrees()

GeoPosition constexpr rose::GeoPosition::toDegrees ( ) const

inline

Convert the position from radians to degrees.

Returns

The position in degrees.

toRadians()

GeoPosition constexpr rose::GeoPosition::toRadians ( ) const

inline

Convert the position from degrees to radians.

Returns

The position in radians.
