public class ShoreManager
extends java.lang.Object

Separate class to manage shore functions for the video range, all this could go in the controller, but might as well keep it separate.

getShoreInterceptList

public java.util.Vector<LatLong> getShoreInterceptList(LatLong origin,
                                                       double trueBearing)

getIntercept

public LatLong getIntercept(LatLong origin,
                            double bearing,
                            LatLong ll1,
                            LatLong ll2)

See if a line drawn at a given bearing from some origin intercepts a line between two other points. If they do, then return the LatLong of the intercept point, otherwise return null.

Parameters:

origin - origin of bearing line

bearing - true bearing (degrees clockwise from North)

ll1 - lat long of start of line segment

ll2 - lat long of end of line segment

Returns:

LatLong of intercept or null

getSortedShoreRanges

public double[] getSortedShoreRanges(LatLong origin,
                                     double trueBearing)
