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.
