TeCoord2D TePolarStereographic::LL2PC

(

const TeCoord2D &

p

)

[virtual]

Pure virtual method that transforms geodetic into projection coordinates.

This method is implemented for each available projection class and represents the so-called direct formulas, which compute projection coordinates from geodetic coordinates.

Parameters:

p	Geodetic coordinates (radian).

Returns:

p Projection coordinates (m).

Note:

Geodetic coordinates must be a valid latitude ([0,pi/2] or [0,-pi/2]) and a valid longitude ([0,pi] or [0,-pi]).

Implements TeProjection.

void TePolarStereographic::LL2PC	(	double	xi,
		double	yi,
		double &	xo,
		double &	yo
	)		const [virtual]

Reimplemented from TeProjection.

(

ostream &

java

)

const [virtual]

Reimplemented from TeProjection.

TeCoord2D TePolarStereographic::PC2LL

(

const TeCoord2D &

p

)

[virtual]

Pure virtual method that transforms projection into geodetic coordinates.

This method is implemented for each available projection class and represents the so-called inverse formulas, which compute geodetic coordinates from projection coordinates.

Parameters:

p	Projection coordinates (m).

Returns:

p Geodetic coordinates (rad).

Note:

X and Y projection coordinates must be both valid, within the typical range of each projection class.

Implements TeProjection.
