DESCRIPTION
i.cca is an image processing program that takes from two to eight (raster) band files and
a signature file, and outputs the same number of raster band files transformed to provide
maximum separability of the categories indicated by the signatures. This implementation
of the canonical components transformation is based on the algorithm contained in the LAS
image processing system. CCA is also known as "Canonical components transformation".
Typically the user will use the g.gui.iclass program to collect a set of signatures and
then pass those signatures along with the raster band files to i.cca. The raster band
file names are specified on the command line by giving the group and subgroup that were
used to collect the signatures.
The output raster map names are built by appending a ".1", ".2", etc. to the output raster
map name specified on the command line.
Parameters:
group=name
Name of the imagery group to which the 2 to 8 raster band files used belong.
subgroup=name
Name of the imagery subgroup to which the 2 to 8 raster band files used belong.
signature=name
Name of an ASCII file containing spectral signatures.
output=name
Output raster map prefix name. The output raster map layer names are built by
appending a ".1", ".2", etc. onto the output name specified by the user.
NOTES
i.cca respects the current geographic region definition and the current mask setting while
performing the transformation.
