Method Detail

• computeDistanceAndBearing

   final Unit computeDistanceAndBearing(Double lat1, Double lon1, Double lat2, Double lon2, FloatArray results)

• computeDistanceAndBearing

   final Unit computeDistanceAndBearing(Double latP1, Double lonP1, Double latP2, Double lonP2, Double a, Double b, Double f, FloatArray results)

• distanceBetween

   final Unit distanceBetween(Double startLatitude, Double startLongitude, Double endLatitude, Double endLongitude, FloatArray results)

  Computes the approximate distance in meters between two locations, and optionally the initial and final bearings of the shortest path between them. Distance and bearing are defined using the WGS84 ellipsoid.

  The computed distance is stored in results0. If results has length 2 or greater, the initial bearing is stored in results1. If results has length 3 or greater, the final bearing is stored in results2.

  Parameters:

  startLatitude - the starting latitude

  startLongitude - the starting longitude

  endLatitude - the ending latitude

  endLongitude - the ending longitude

  results - an array of floats to hold the results

• computeDistanceFast

  @Synchronized() final Double computeDistanceFast(Location loc1, Location loc2)

  Compute distance on Earth approximated as sphere.

  Parameters:

  loc1 - first location

  loc2 - second location

• computeDistanceFast

  @Synchronized() final Double computeDistanceFast(Double lat1, Double lon1, Double lat2, Double lon2)

  Compute distance on Earth approximated as sphere.

  Parameters:

  lat1 - latitude of first point

  lon1 - longitude of first point

  lat2 - latitude of second point

  lon2 - longitude of second point

• computeDistanceAndBearingFast

   final Unit computeDistanceAndBearingFast(Double latP1, Double lonP1, Double latP2, Double lonP2, DoubleArray results)

  Compute distance and bearing on Earth approximated as sphere. <br></br><br></br>Compute is based on Haversine formula http://en.wikipedia.org/wiki/Haversine_formula <br></br><br></br>Precision is around 99.9%, speed around 5x faster then above method.

  Parameters:

  latP1 - latitude of first point

  lonP1 - longitude of first point

  latP2 - latitude of second point

  lonP2 - longitude of second point

  results - one (only distance) or two sized array for a results
