Hi Denis:
It seems like what you really want to create is a BandedRaster,
by using Raster.createBandedRaster().
Your code now is creating a Raster with a PixelInterleavedSampleModel,
one where the data is organized as ABCDABCDABCD....., where A,B,C,D are the
samples of each band. A BandedSampleModel organizes the data as
all samples of band A, followed by all samples of band B, etc, which
I think is what you were trying to do. The data can be in a single
bank, with band indices indicating the starting points of each band,
or in multiple banks, with band indices most likely to all be zero.
Also, all your createChild() calls in you example were identical,
(maybe a typo for this email ?).
They need to indicate where each child is located in the parent
raster.
Hope this helps,
Link Perry
