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