ImageLayer translation?

Hi

Added mapnode to positionAttitudeTransformation (PAT). Map of the mapnode
is added with an imagelayer.
I keep incrementing the position of PAT in y axis by 1.0 which moves imagelayer in y direction.
Here, I would like to know how much the imagelayer moves geographically(degrees), in terms of
longitude. Observed that GeoExtent of the imagelayer is not changed on PAT position change.

How can it be done?
