GeodeticPoint
public GeodeticPoint(double latitude, double longitude, double altitude)
Build a new instance. The angular coordinates will be normalized so that the latitude is between ±π/2 and the longitude is between ±π.- Parameters:
latitude
- latitude of the point (rad)longitude
- longitude of the point (rad)altitude
- altitude of the point (m)
-

Method Detail
-
getLatitude
public double getLatitude()
Get the latitude.- Returns:
- latitude, an angular value in the range [-π/2, π/2]
-
getLongitude
public double getLongitude()
Get the longitude.- Returns:
- longitude, an angular value in the range [-π, π]
-
getAltitude
public double getAltitude()
Get the altitude.- Returns:
- altitude
-
getZenith
public Vector3D getZenith()
Get the direction above the point, expressed in parent shape frame.The zenith direction is defined as the normal to local horizontal plane.
- Returns:
- unit vector in the zenith direction
- See Also:
getNadir()
-
getNadir
public Vector3D getNadir()
Get the direction below the point, expressed in parent shape frame.The nadir direction is the opposite of zenith direction.
- Returns:
- unit vector in the nadir direction
- See Also:
getZenith()
-
getNorth
public Vector3D getNorth()
Get the direction to the north of point, expressed in parent shape frame.The north direction is defined in the horizontal plane (normal to zenith direction) and following the local meridian.
- Returns:
- unit vector in the north direction
- See Also:
getSouth()
-
getSouth
public Vector3D getSouth()
Get the direction to the south of point, expressed in parent shape frame.The south direction is the opposite of north direction.
- Returns:
- unit vector in the south direction
- See Also:
getNorth()
-
getEast
public Vector3D getEast()
Get the direction to the east of point, expressed in parent shape frame.The east direction is defined in the horizontal plane in order to complete direct triangle (east, north, zenith).
- Returns:
- unit vector in the east direction
- See Also:
getWest()
-
getWest
public Vector3D getWest()
Get the direction to the west of point, expressed in parent shape frame.The west direction is the opposite of east direction.
- Returns:
- unit vector in the west direction
- See Also:
getEast()
