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.
