You can now add your own 360 degree photographs to Google Maps. Well you can if you use the new Photo Sphere app on a Nexus 4 phone.
The app allows Nexus 4 owners to easily and quickly capture 360 degree photographs. Once you have captured a panorama the app allows you (if you want) to share it and submit it to Google Maps for the world to see. Your panoramas can then appear on Google Maps, Google Earth, Google Search, Google+ Local, and even third-party sites using the Google Maps API.
You can view the (few) panoramas already submitted to Google Maps on this new dedicated panorama page on the Google Maps Street View Gallery.
