Excluding ground plane or surface from Global reflection map, Brazil

Rendering Brazil
1

Hey brazil users

Is there any way I can exclude the ground plane from reflecting the reflection map.
I want a very basic black background with the hull reflecting a global map of the sky but not the ground plane- I want the ground plane ( or planar surface) to reflect hull only.

Any smart ideas!
