Trouble with GeotiffWriter

List,

I finally got some netCDF output that is truly CF-compliant, and I 
managed to get past the part of GeotiffWriter that establishes the 
coordinate system.  Now, it is raising an exception in 
'getYXDataInBox'.  The failing point is the 'try/catch' block, where it 
is reading dataVolume.  I tried a number of different ways to create the 
LatLonRect, but none made any difference.

I'm attaching my Java code.  If anyone is interested, I can send the 
netCDF off-list.  The netCDF is only 250k...not sure if that is too much 
for the list or not.

I'm using netcdf-Java 2.2.10.

Matt

P.S.  I'm not much of an OO programmer, so try not to laugh too much at 
my code!  ;-)
