Google acquired a photo community in 2007 called Panoramio and users of Google Earth are able to access 2D photos in the photo layer from that site as well as panoramic photos from another site called 360.net that colletcs panoramic pictures from all over the net. 360.net’s 360 Cities had been integrated into Google Earth previously in the Gallery area but this appears to be a better integration of the photographs.
Panoramic photographs used in Google Earth taken from 360 Cities have a red square icon and pictures from Panoramio are marked in a similar manor with a blue icon. If you click on the blue icon, you will be shown a bubble with a panoramic image from Panoramio while a red icon will show you a bubble from 360.net. If you want a larger image, you only need to click the icon again. You can also click between the two different panoramic photos if you want to check out a different view.
Not all places have a panoramic picture to show as of yet but it seems the members of 360.net are working to close any gaps and panoramic photographs are uploaded to the site on a regular basis allowing the integration with Google Earth to be constantly changing due to new photos every day.
Because of a vibrant community of travelers and photographers 360 Cities has a vast database of panoramic pictures all linked to Google Earth. The new panoramic photo layer embedded in the Google Earth software can not only allow you to get a more immersive view of the city or landmark you wish to see but it could save you the trouble of buying a plane ticket to visit the site in person.
