	Loxodrome (double a, double f)
	Constructor for the Loxodrome class.
BearingRange	BearingRange (GeoPos gp0, GeoPos gp1)
	Solves the inverse loxodrome problem. There are infinitely many such curves connecting two given points. This function selects the shortest one, with a preference for going east in case of antipodal points.
GeoPos	BearingRangeToPos (GeoPos gp0, BearingRange br)
	Solves the direct loxodrome problem.
GeoPos[]	IntermediatePos (GeoPos pos0, GeoPos pos1, int n)
	Computes evenly spaced waypoints along the shortest loxodrome between two given positions.

Detailed Description

Class representing a given ellipsoid for precise loxodrome or rhumbline calculations.

Constructor & Destructor Documentation

Loxodrome()

TPG.GeoUnits.Loxodrome.Loxodrome ( double  a, double  f  )

inline

Constructor for the Loxodrome class.

Parameters

a	equatorial radius (meters)
f	flattening of ellipsoid

Member Function Documentation

BearingRange()

BearingRange TPG.GeoUnits.Loxodrome.BearingRange ( GeoPos  gp0, GeoPos  gp1  )

inline

Solves the inverse loxodrome problem. There are infinitely many such curves connecting two given points. This function selects the shortest one, with a preference for going east in case of antipodal points.

Parameters

gp0	originating position
gp1	target position

Returns

Bearing and range along the loxodrome between the given points

BearingRangeToPos()

GeoPos TPG.GeoUnits.Loxodrome.BearingRangeToPos ( GeoPos  gp0, BearingRange  br  )

inline

Solves the direct loxodrome problem.

Parameters

gp0	originating position
br	Bearing and range along the loxodrome

Returns

end position. If the range is long enough thar the line reaches a pole, NaN is returned for longitude

IntermediatePos()

GeoPos[] TPG.GeoUnits.Loxodrome.IntermediatePos ( GeoPos  pos0, GeoPos  pos1, int  n  )

inline

Computes evenly spaced waypoints along the shortest loxodrome between two given positions.

Parameters

pos0	Start position
pos1	End position
n	Number of waypoints (>= 2), including start and end points

Returns

Array of waypoints
