Dear Ethan, Don, others,

thanks for discussing this in detail. I would like to contribute if I
can, although I don't have any experience coding with the NetCDF-Java
interface so far.
I would be in favour of a generic solution, but I'm wondering if, in
this case, it isn't something that should go into IDV itself. The
fact that a grid wraps and how to deal with it is something
application-domain specific. NetCDF (theoretically) doesn't have to
contain earth grids. There are other applications where the
functionality would make sense (direction axes), so it could be seen
as a generic dimension property (solve in NetCDF) or as something
earth-grid specific (solve in IDV). If it's solved in NetCDF,
shouldn't it be solved in the base C library as well?
Ferret (noaa) has a similar problem, and solves it in the application
with a "modulo" flag for dimensions and recognition of specific lon
dimensions. I'm not sure if they split requests in 2 when requesting
a small region, but I can find out if there's an interest.
Kind regards,
Hein
