Method Detail

create

public static LatLonPoint create(double lat,
                                 double lon)

Create a LatLonPoint.

getLatitude

public abstract double getLatitude()

Returns the latitude, between +/- 90 degrees.

getLongitude

public abstract double getLongitude()

Returns the longitude, between +/-180 degrees

nearlyEquals

public boolean nearlyEquals(LatLonPoint that)

Returns the result of nearlyEquals(LatLonPoint, double), with Misc.defaultMaxRelativeDiffDouble.

nearlyEquals

public boolean nearlyEquals(LatLonPoint that,
                            double maxRelDiff)

Returns true if this point is nearly equal to that. The "near equality" of points is determined using Misc.nearlyEquals(double, double, double), with the specified maxRelDiff.

Parameters:

that - the other point to check.

maxRelDiff - the maximum relative difference the two points may have.

Returns:

true if this point is nearly equal to that.

toString
