Ran Ben Avraham takes a look at creating a detailed terrain that one might see in some sort of fictional scanner interface by the use of displacement maps in FreeFrom Pro for After Effects. Ran Ben Avraham also notes and explores the differences between FreeForm and FreeForm Pro.
Check out the tutorial for Create a Detailed Digital Terrain Scan in After Effects using FreeForm Pro here.

from the tutorial description: In this tutorial we are going to create a 3D futuristic terrain scanner. Step-by-step, we will create monochromatic displacement maps and use them to extrude the 3D mountain like shapes. We will explore the difference between the old version of FreeForm (the DigiEffects version, bundled with AE CS5) and the new FreeForm v2, which is considerably faster after having some excellent optimizations to the source code.
