Class ZonalStatsDemo

java.lang.Object
  jaitools.demo.zonalstats.ZonalStatsDemo

public class ZonalStatsDemo
extends Object

Demonstrates using the ZonalStats operator to calculate summary statistics of values in a data image within zones defined by a zone image. In this example the data image contains uniform random values and the zones are equal in size, so we expect the value of each summary statistic to be very similar across zones.
