Class RasterZonalStatistics2

Object

RasterZonalStatistics2

All Implemented Interfaces:

GSProcess, RasterProcess

public class RasterZonalStatistics2
extends Object
implements RasterProcess

This class wraps the "ZonalStats2" OperationJAI and executes the selected operation with the defined parameters. No transformation of the optional classifier image is needed because inside the process the classifier image is already transformed by the GridCoverage2DRIA operation. By default the input band is set 0, and the statistics to MEAN, MAX, MIN, EXTREMA, VARIANCE, STANDARD DEVIATION. The main difference between this class and RasterZonalStatistics is the fact that this operation will calculate the requested statistics for all the SimpleFeatures in a single step, without having to iterate on the features. This Process is a simple wrapper of the ZonalStatistics operation
