Class Summary

Class	Description
Absolute	Computes the mathematical absolute value of each sample value.
Add	Create a new coverage as the sum of two source coverages by doing pixel by pixel addition: result[0][0] = source0[0][0] + source1[0][0] ... ...
AddConst	Adds constants (one for each band) to every sample values of the source coverage.
Convolve	Computes each output sample by multiplying elements of a kernel with the samples surrounding a particular source sample.
Crop	The crop operation is responsible for selecting geographic subarea of the source coverage.
DivideByConst	Divides every sample values of the source coverage by constants (one for each band).
Exp	Takes the exponential of the sample values of a coverage.
Extrema	This operation simply wraps JAI Extrema operations described by ExtremaDescriptor inside a GeoTools operation in order to make it spatial-aware.
FilteredSubsample	This operation is simply a wrapper for the JAI FilteredSubsample operation which allows me to arbitrarly scale a rendered image while smoothing it out.
GradientMagnitude	Edge detector which computes the magnitude of the image gradient vector in two orthogonal directions.
Histogram	* This operation simply wraps JAI Histogram operations described by HistogramDescriptor inside a GeoTools operation in order to make it spatial-aware.
Interpolate	Specifies the interpolation type to be used to interpolate values for points which fall between grid cells.
Invert	Inverts the sample values of a coverage.
Log	Takes the natural logarithm of the sample values of a coverage.
MaxFilter	For each position of the mask, replaces the center pixel by the maximum of the pixel values covered by the mask.
MedianFilter	For each position of the mask, replaces the center pixel by the median of the pixel values covered by the mask.
MinFilter	For each position of the mask, replaces the center pixel by the minimum of the pixel values covered by the mask.
Multiply	Create a new coverage as the multiplication of two source coverages by doing pixel by pixel multiplication: result[0][0] = source0[0][0] * source1[0][0] ... ...
MultiplyConst	Multiplies every sample values of the source coverage by constants (one for each band).
Resample	Resample a grid coverage using a different grid geometry.
Rescale	Maps the sample values of a coverage from one range to another range.
Scale	This operation is simply a wrapper for the JAI scale operation which allows me to arbitrarily scale and translate a rendered image.
SelectSampleDimension	Chooses N sample dimensions from a grid coverage and copies their sample data to the destination grid coverage in the order specified.
SubsampleAverage	This operation is simply a wrapper for the JAI SubsampleAverage operation which allows me to arbitrarily scale a rendered image while smoothing it out.
SubtractConst	Subtracts constants (one for each band) from every sample values of the source coverage.
SubtractFromConst	Subtracts every sample values of the source coverage from constants (one for each band).
Warp	This operation is simply a wrapper for the JAI Warp operation
ZonalStats	This operation simply wraps Jai-tools Zonalstats operations described by ZonalStatsDescriptor inside a GeoTools operation in order to make it spatial-aware.

Package org.geotools.coverage.processing.operation Description

List of coverage operations. This package is useful for documentation purpose since class names match exactly operation names, and the javadoc for each class provides a table of valid arguments. But the classes provided there should not be used directly. There is no need to instantiate them, since it is already done by the processor which manage them.
