Hi Robert...
Okay, now I understand why you need the GVAR nav. Fact is, the GINI
images are re-projected at the data source before being sent on
NOAAPort.
If you are affiliated with a University, then there is a Unidata
server available that has high-rest GVAR images; otherwise, you would
have to contract with SSEC to get realtime GVAR data from our servers.
If you don't need realtime data, you might look at NCDC and see if
the CLASS data would meet your needs...last I looked they did provide
data in AREA format as one of the options. See
<http://www.ncdc.noaa.gov/oa/rsad/satfaq/class-goes-read.html> and
<http://www.class.ncdc.noaa.gov/saa/products/search?datatype_family=GVAR_IMG>
Finally, you probably could re-project the TANC-nav data by getting an
AREA file that has the desired GVAR navigation and then from Jython,
resample the TANC-nav data into it.
