Google Maps has a hidden feature that allows anyone to zoom in extremely close on some satellite pictures. This screenshot shows the closest zoom available for a location in the Sahara desert. Using this hidden feature, you can zoom in a little closer in almost any Metropolitan area, and MUCH closer in select areas.
Here's Google Blogoscoped's instructions on utilizing this feature:
1. Select a location and switch to satellite view
2. Zoom in as far as you can, and click â€œlink to this pageâ€ at the top right
3. Now replace the â€œzâ€ parameter in the URL with a higher value, e.g. 20, 22, or 23, and wait. Some locations will now show more detailed imagery
Since people are good at identifying faces at low resolutions, someone should be able to identify the guy looking skyward in the upper right. My vote is that he's Mahmoud Ahmadinejad, the Iranian President, in hiding.
