Do you remember that guy who walked all the way through the Grand Canyon a couple of years ago, with a 40-pound Google Trekker strapped to his back? He was helping Google digitize the world as you now regularly see it on Google Maps' Street View.
The vast majority of those maps are recorded with huge, 360-degree cameras on top of Google cars. You may have seen one driving through your neighborhood.
Even if you haven't, you've seen the results. Just type in your home address on Google Maps, then select Street View. You'll see your house and, click on the arrows, it'll show you an incredible, 360-degree view of your street.
It's not just major streets, or the United States, either. Much of the world's roads are now captured in 360-degree images, thanks to Google and its giant cameras.
Of course, technology is always advancing, which for the most part means getting better with each new version. Which is just what's happening with the Ricoh Theta camera, which is rolling out its new, improved Theta S model for about $349, in time for Christmas. If you get one, you can help Google digitize the rest of the world.
