The grib data represent a disc of the earth so the corners are off the
earth, thus the NaN's. Even so, the VerticalPerspectiveView does not
presently support a non-spherical earth, so the data are not exactly
navigated. This is a known issue and one that we have not yet had the
time to address.

Hi,
We have a GRIB file can mostly be read using NetCDF-Java, except that
the GridCoordSystem's lat-lon bounding box is a set of four NaNs. It
uses a VerticalPerspectiveView projection. The attached test file may
help to diagnose the problem and produces the following output:
class ucar.unidata.geoloc.projection.VerticalPerspectiveView
ll: NaNS NaNW+ ur: NaNS NaNW
The data file itself can be downloaded from
http://dl.dropbox.com/u/2984763/MSG2-SEVI-MSGCLMK-0100-0100-20091028120000.000000000Z-958792.grb.
Can anyone offer any pointers? Is there a bug in the
VerticalPerspectiveView code?
Thanks,
Jon
