Stuart-
I moved this over to idvdevelopers because these programming
questions are best suited for that list instead of idvusers.
We don't want to scare any novices off. ;-)
Are you printing out what gg is? Is it possible that you are
not using the right GeoGrid (e.g. the one for surface_temperature)?
How are you subsetting the grid? The name is only for creating the
FlatField. You need to have the right geogrid to get the correct
data.

To update my previous mail about using a Contour2DDisplayable object
and a GeoGrid from a nc file, I have discovered something odd. I
printed out the domain and range values of the FlatField i am using
for the Displayable. the domain has X and Y values as I expected, but
the range values are off.
Given that I do this:
GeoGridAdapter gga = new GeoGridAdapter( ggds, gg,
"surface_temperature" );
FieldImpl fi = gga.getData();
I expected my flatfield to have values from the surface_temperature
variable. However I am seeing values from some other variable, and
from within the middle of the grid of data too.
It's as though the netcdf offset logic is awry.
Or maybe I am using the classes wrong.
Anyway, the Contour2Ddisplayable is handling the map projection from
X, Y in the grid to lat, lon, so it is not that that is the issue, as
I previously thought.
