<h1>Module Status</h1>

<p>The code of this module has been previously used as a dependency of a custom GeoTools/Geoserver setup to compute zonal summary statistics.<br />
As an instance, it allows to compute statistics like min, max, mean, median, standard deviation, variance and sum of the pixels contained within a specified zone of a coverage/image.<br />
We are working to create a stable jai-tools 1.0.0 release to be used by that module. Our final aim is to include these operations in the coverage module, beside the other available (JAI-based) <a href="http://geotools.org/javadocs/org/geotools/coverage/processing/operation/package-summary.html">operations</a></p>

<p>Within the module, there is a standalone test class which allows to perform basic zonal statistics over a DEM sample data.</p>
