Satellite picture of map once so distorted (9)
I believe the answer is:
moonscape
'satellite picture' is the definition.
(picture of the moon, Earth's satellite)
'map once so distorted' is the wordplay.
'distorted' indicates anagramming the letters.
'map'+'once'+'so'='maponceso'
'maponceso' with letters rearranged gives 'MOONSCAPE'.
'of' acts as a link.
(Other definitions for moonscape that I've seen before include "Barren terrain" , "desolate scene" , "piece for the night?" , "Rocky terrain" , "Unearthly vista" .)
