There are a range of commercial support providers; but basically asking for a
complete program is a bit beyond what you can expect from a community user list
:-)
You are welcome to share your code and collaborate with those on the list to
work towards a solution; I do my best to capture as many examples as I can for
the user docs.
Still what you are asking about sounds just like "how do I read a value out of
a coverage"? I think you can do that with "evaulate":
GridCoverage2D coverage = reader.read(null); // direct access DirectPosition
position = new DirectPosition2D( crs, x, y); double[] sample = (double[])
coverage.evaluate( position ); // assume double // resample with the same array
sample = coverage.evaluate( position, sample );
