Method Details

calculatePath

public static double calculatePath(List<GlobalCoords3D> path,
 List<PropagationApex> bounces,
 GlobalCoords3D start,
 GlobalCoords3D end,
 double initialAzimuth)

geodesicDistanceToStraightLineDistance

public static double geodesicDistanceToStraightLineDistance(double geodesicDistance)

It is assumed the Earth is round for this calculation, so there will be a margin of error. As the result is used in a calculation of angle shown to the nearest degree, it's probably OK for now This calculates the straight line distance between two points on the Earth, through the Earth, using the geodesic distance on the surface of the Earth.

Parameters:

geodesicDistance - distance between two points traversing across the Earth surface

Returns:

straight line distance between two points, direct, through the Earth.

areCoordsEqual

public static boolean areCoordsEqual(org.gavaghan.geodesy.GlobalCoordinates myCoords,
 org.gavaghan.geodesy.GlobalCoordinates coords)

Check that coordinates are equal or at least very close

Parameters:

myCoords - my coordinates

coords - their coordinates

Returns:

true if the latitude and longitude are within 0.0001 of each other

getBearing

public static Double getBearing(org.gavaghan.geodesy.GlobalCoordinates myCoordinates,
 org.gavaghan.geodesy.GlobalCoordinates coordinates)
