Don't base your experience with GOES that ITTVIS needs better map
projection sup****t. GOES is a notorious wobbler. NOAA provides GOES
image as raw data. That is why NASA GSFC provides complex algorithm to
do the navigation and they don't work all the time, either. Loop some
GOES data and watch the clouds dance. Especially after they do some
station keeping.

EUMETSAT does a great job remapping their METEOSAT data before they
releasing it to the public. Navigation wise, working with METEOSAT
data is a dream and GOES data can be a pain most of the time.
