Method Detail

regionToKML

public static void regionToKML(Region region,
                               String filename,
                               Color c)

locListToKML

public static void locListToKML(LocationList locs,
                                String filename,
                                Color c)

getFractionInside

public static double getFractionInside(Region region,
                                       Iterable<Location> locs)
                                throws NullPointerException,
                                       IllegalArgumentException

The returns the fraction of points in the given collection of locations that is inside the given region. This will commonly be used with the AbstractEvenlyGriddedSurface class to determine the fraction of a fault surface that is inside of a region.

Parameters:

region - the region for which to test

locs - any instance of Iterable, for example, ArrayList or EvenlyGriddedSurface.

Returns:

fraction of locations inside the given region

Throws:

NullPointerException - if region or locs is null

IllegalArgumentException - if locs is empty

getNodeShape

public static Area getNodeShape(Location p,
                                double w,
                                double h)

Returns the Region spanned by a node centered at the supplied location with the given width and height.

Parameters:

p - Location at center of a grid node

w - node width

h - node height

Returns:

the node's Region

main

public static void main(String[] args)
