More aerial views; National Geographic app; Google Maps for the indoors

A few cool things to point you toward today:

More Cities get “Aerial View” in Google Maps — Portland, OR and Sacramento and Oakland, CA all have new “bird’s eye” imagery from Google.

National Geographic launches iPhone app — It allows a variety of mapping sources, styles and other cool stuff.

Micello Launches “Google Maps for the Indoors” — This thing could be very cool if they can expand their coverage.  They have “over 250″ maps so far, but none on the eastern half of the US.
