Google Satellite Maps:
Google is now offering a new satellite mapping feature available on Google Maps. It lets you see satellite pictures of particular locations; for example, here is a photograph of George Washington University Law School in Washington, DC. This story about the service focuses on the privacy concerns, which seem relatively modest now but will become quite troubling if and when the resolution of the maps improves.

  Notably, Google has blacked out or blurred some areas with national security importance. For example, this picture of the White House has the contour of the buildings blacked out. Interestingly, Congress's image is blurred while the Supreme Court's is clear: see the picture of both here.
