here's the content of a GSFC-generated GOES TIFF image:

The TIFF file is here: http://goes.gsfc.nasa.gov/goeseast-lzw/overview/ir3/latest.tif
¿How can I get/calculate the geographic bounds from this information or from the GeoTIFF file itself?
¿Can I do this somehow opening the file in QGIS? Do I have to develop some script?
I only need to do this one time.
Thanks to anybody dedicating his/her time on answering this!

Sure,
Firstly, open it in QGIS, and then in the menu at the top go to Raster->Miscellaneous->Information.
Select the layer in the "Input-file" drop-down box (if it's not already there) then press OK, and it will create a load of text relating to information about the layer in a box called "Raster Info".
If you scroll down this text, you will get to a line that says "Corner Coordinates", the following 4 lines look like this:
and describe the coordinates of each corner (the geographic bounds) (in my example, given as both projected and geographic coordinates).
Is that what you're after?
Note: if you can't see any part of Raster->Miscellaneous->Information in the menu, go to Plugins->Manage and Install Plugins, and make sure that the box next to "GDAL Tools" is ticked, this will make it appear
