Geodetic ()

Constructor. Creates a new Geodetic class instance and sets the WGS origin to zero.

Geodetic (dvec3 origin)

Constructor. Creates a new Geodetic class instance and sets the WGS origin by using the given data.

Arguments

• dvec3 origin - The origin of the WGS coordinate system.

Geodetic (double latitude, double longitude, double height)

Constructor. Creates a new Geodetic class instance and sets the WGS origin by using the given data.

Arguments

• double latitude - The latitude of the origin of the WGS coordinate system in degrees.
• double longitude - The longitude of the origin of the WGS coordinate system in degrees.
• double height - The height of the origin of the WGS coordinate system in degrees.

double getDegrees (double degrees, double minutes, double seconds)

Returns the coordinate value in degrees.

Arguments

• double degrees - Degrees of a coordinate.
• double minutes - Minutes of a coordinate.
• double seconds - Seconds of a coordinate.

Return value

Coordinate value in degrees.

double getDelta (dvec3 position)

Calculates the offset between geodetic and Cartesian heights.

Arguments

• dvec3 position - Position coordinates.

Return value

Delta.

double getRadius (dvec3 sin_latitude)

Returns the radius by using the given sine of the latitude.

Arguments

• dvec3 sin_latitude - Sine of the latitude.

Return value

Radius.
