20 Dec. NY Times - Google Offers a Bird's-Eye View, and Some Governments Tremble.

Google Earth is the most conspicuous recent instance of increased openness in a digitally networked world, where information that was once carefully guarded is now widely available on personal computers. Many security experts agree that such increased transparency - and the discomfort that it produces - is an inevitable byproduct of the Internet's power and reach.

American experts in and outside government generally agree that the focus on Google Earth as a security threat appears misplaced, as the same images that Google acquires from a variety of sources are available directly from the imaging companies, as well as from other sources. Google Earth licenses most of the satellite images, for instance, from DigitalGlobe, an imaging company in Longmont, Colorado.
