Method Detail

average

public static com.vividsolutions.jts.geom.Coordinate average(com.vividsolutions.jts.geom.Coordinate c1,
                                             com.vividsolutions.jts.geom.Coordinate c2)

Returns the average of two Coordinates.

Parameters:

c1 - one coordinate

c2 - another coordinate

Returns:

a new Coordinate with the average x and average y

average

public static com.vividsolutions.jts.geom.Coordinate average(Collection coordinates)

Parameters:

coordinates - not empty

closest

public static com.vividsolutions.jts.geom.Coordinate closest(Collection coordinates,
                                             com.vividsolutions.jts.geom.Coordinate p)

Parameters:

coordinates - not empty

add
