Method Detail

zMinMax

public static double[] zMinMax(com.vividsolutions.jts.geom.Coordinate[] cs)

Determine the min and max "z" values in an array of Coordinates.

Parameters:

cs - The array to search.

Returns:

An array of size 2, index 0 is min, index 1 is max.

interpolate

public static double interpolate(com.vividsolutions.jts.geom.Coordinate firstCoordinate,
                                 com.vividsolutions.jts.geom.Coordinate lastCoordinate,
                                 com.vividsolutions.jts.geom.Coordinate toBeInterpolated)

Interpolates a z value (linearly) between the two coordinates.

Parameters:

firstCoordinate -

lastCoordinate -

toBeInterpolated -

Returns:

contains2D

public static boolean contains2D(com.vividsolutions.jts.geom.Coordinate[] coords,
                                 com.vividsolutions.jts.geom.Coordinate coord)

Checks if a coordinate array contains a specific coordinate. The equality is done only in 2D (z values are not checked).

Parameters:

coords -

coord -

Returns:
