GOOGLE ACQUIRES KEYHOLE

I wonder what Keyhole exactly does and how it fits into Google's expanding strategic view:

Google Inc. (Nasdaq: GOOG) has acquired Keyhole Inc., a Mountain View, Calif.-based digital mapping company. No financial terms were disclosed. Keyhole had raised venture capital funding from 550 Digital Media Ventures, Intrinsic Graphics Inc. and In-Q-Tel, the venture capital affiliate of the CIA.
