Interface PointI

All Known Implementing Classes:

Point

public interface PointI

extends GeoI, PointI

An interface to abstractly access a point in the geographic coordinate system.

Method Summary
double	directionTo(PointI point)           Returns the direction to the argument.
double	distanceProxyTo(PointI point)           Returns an easily computable proxy that can be used to compare the distance from this point to the argument point.
double	distanceTo(PointI point)           Returns the great circle distance in the units of the ellipsoid.
double	latitude()           Returns the latitude coordinate.
double	longitude()           Returns the longitude coordinate.

Method Detail

longitude

public double longitude()

Returns the longitude coordinate.

latitude

public double latitude()

Returns the latitude coordinate.

distanceProxyTo

public double distanceProxyTo(PointI point)

Returns an easily computable proxy that can be used to compare the distance from this point to the argument point.

Specified by:

distanceProxyTo in interface GeoI

distanceTo

public double distanceTo(PointI point)

Returns the great circle distance in the units of the ellipsoid.

Specified by:

distanceTo in interface GeoI

directionTo

public double directionTo(PointI point)

Returns the direction to the argument. The return value is in the range -PI to +PI and is measured from north. If angle is positive if 'point' is clockwise and negative if it is counterclockwise.
