How simple it is?
i do not know exactly,
The technique is used on all digital maps... i am not an expert, but the technique is there to be used.
Some parts of the image are truly badly stitched - the MontBlanc part is mostly very good..of course.. except for the cabin
The photo is taken from the Italian side- The cabin you see is really nice to take if you are there.
It is purely for the sightseeing- takes 20 minutes and stops now and then to give you a quiet view.
It connects italy and France- moves horizontally and is made by the Suisse if i remember correctly.
Halfway it is only supported once. I have a big picture of the view from it hanging on my wall that i took with a 4x5 inch and i can see even more detail on this panorama...
So must say they photographed the mountain as big as it really is.
Since i do not see any moved or vibrated images, the weather must have been very good and not to much wind.
