Method Detail

move

public abstract void move(TwoDCoordinate c,
                          double xMeters,
                          double yMeters)

distance

public abstract double distance(TwoDCoordinate c1,
                                TwoDCoordinate c2)

Returns the Euclidean distance in meters between two coordinates

xDistance

public abstract double xDistance(TwoDCoordinate c1,
                                 TwoDCoordinate c2)

Returns a signed distance in meters in the x direction between two coordinates. It represents c1.longitude - c2.longitude in meters.

yDistance

public abstract double yDistance(TwoDCoordinate c1,
                                 TwoDCoordinate c2)

Returns a signed distance in meters in the y direction between two coordinates. It represents c1.latitude - c2.latitude in meters.

zDistance

public abstract double zDistance(ThreeDCoordinate c1,
                                 ThreeDCoordinate c2)

Returns a signed distance in meters in the z direction between two coordinates. It represents c1.elevation - c2.elevation in meters.

metersToLatitudeUnits
