<p>Do you suggest the image itself might be corrupt?</p>
<p>I can see the top of the image without noise if I extract
the individual bands using pygac and then I create a TCI
with GDAL:<br>

there, GDAL community!<br>
<br>
I'm experiencing some issues while warping a NOAA 19
image. I'm running <br>
a simple:<br>
<br>
gdalwarp NSS.LHRR.NP.D16020.S1834.E1846.B3581920.WI
warped.tif<br>
<br>
When I display the result in QGIS, it seems that the
image is a little <br>
cropped and has some noise at the top:<br>
<br>

<br>
I've also tried with NOAA 14 and 16 datasets and they
look as expected, <br>
so I guess that the NOAA-19 format might not be fully
supported.<br>
<br>
Anyway, I would like to hear from you if there's
something I am missing, <br>
before filing an issue or attempting a fix.<br>
<br>
Thanks in advance.<br>
<br>
Regards,<br>
Francisco<br>
