fr.cnes.sirius.patrius.math.geometry.euclidean.threed.AzimuthElevationCalculator

public class AzimuthElevationCalculator
extends Object

Compute mathematical Azimuth and Elevation of a Point, defined by its Cartesian coordinates in a Frame whose x, y axis and "Reference Azimuth" axis are in the same Plane. Frame x axis is defined by its frameOrientation (counted trigowise, not clockwise !) from the "Reference Azimuth" The Point Azymuth is the angle (counted clockwise) from the "Reference Azymuth" The Point Elevation is the angle (counted trigowise) from the x,y plane and the Point

Constructor Detail

AzimuthElevationCalculator

public AzimuthElevationCalculator(double frameOrientation)

Constructor

Parameters:

frameOrientation - Oriented angle (trigowise, radian) between the "Reference Azimuth" and the Frame's x axis Example : If "Reference Azimuth" is aligned with the local North of a local topocentric frame then a frameOrientation of -0.785 (=> -45°) means that the x axis of the Frame points to North-East

Method Detail

getElevation

public double getElevation(Vector3D point)

Compute the Elevation of a point defined by its Cartesian coordinates in a Frame whose x, y and "Reference Azimuth" axis are in the same Plane

Parameters:

point - Point Cartesian coordinates / Frame

Returns:

elevation The angle (trigowise, radian) between the x,y plane and the point

getAzimuth

public double getAzimuth(Vector3D point)

Compute the Azymuth of a point defined by its Cartesian coordinates in a Frame whose x, y and "Reference Azimuth" axis are in the same Plane

Parameters:

point - Point Cartesian coordinates / Frame

Returns:

azimuth The angle (clockwise, radian) between the "Reference Azimuth" and the point projected in x,y plane

getFrameOrientation

public double getFrameOrientation()

Returns the frame orientation.

Returns:

the frame orientation
