[gdal-dev] reading NOAA-19 AVHRR

[Even Rouault]

Knut-Frode,

I've skimmed quickly through the driver code and if you are lucky, it is
probably just a matter of changing a few lines (well, I can be wrong).

If you have a debug build of GDAL, you can first try to run "gdalinfo --debug on
avhrr_20120227_235800_noaa19.hrp" . My guess (based on
http://en.wikipedia.org/wiki/NOAA-19 saying that NOAA-19 = NOAA-N' and NOOA-N'
appearing in commented code of the driver...) would be that you would see :
"Unknown spacecraft ID "8"".

If so, you could test the following patch :

Perhaps Andrey Kiselev, the author of the driver, would have better clues.
