Google Earth!

Yet another flagship product of Google.

Google recently bought a company (called 'keyhole' - I think so), together with this product. It is one of the best online stuff that I have downloaded.

Using this tool you can get a 'birds eye view' of any (most of) place in US (and many other places across the globe), given its address. I tried to see my apartment, wow! I could even see the pavement near my door, it is that much accurate.

Besides it also provides options to see Dining places, Gas stations etc nearby the given address.

Hats off to the team that developed it.
