Hi Mitch,
you should better include the whole list in your reply, so that others
can benefit (or help).
If you want to run gdal commands in a QGIS installation, you have to run
the OSGE4W shell, then enter commands inside the shell.
This looks quite old-fashioned, and you need to remember old
DOS-commands to navigate between folders, but otherwise the environment
for GDAL is not setup correctly.

Andre,
My gdal doesn’t recognize VIIRS datasets now! Its odd because gdal
works perfectly in qGIS. Any idea why all the gdal capability is not
available in qGIS? I could just do it in the customized gdal scripts
in gdal_transform but it doesn’t allow me.

Is this raster data?
I think you have georeferenced it.

It is not that easy. The data is raw data from a satellite flight. The
HDF contains several subdatasets, including longitude and latitudes of
every cell. Unfortunately, the cell coordinates are not equally spaced,
and there is no CRS given.
The best result I get is transforming the longitude, latitude and
aerosol subdatasets with gdal_transform to XYZ format, then stitch
them together with LibreOffice Calc, and import them as delimited
text.
It is possible to extract single bands with gdalwarp. This seems to
work, but the GCP information inside the file is wrong. Longitudes
are added by 180°, and the last line of GCP matches 0/0 to 0/0,
which makes no sense to me.
Reading the data with python code inside a plugin might be an
alternative.
Greetings, André Joost
