Travel the Globe from Your Chair with 360Cities

360CitiesCzech photographer Jeffrey Martin and his partners host this collection of “panos” or 360-degree panorama shots taken all around the world and even under the sea. To virtually travel the globe, just do a keyword search for your favorite destination or just browse locations on the world map.

To orient viewers, all panos are pinned to a location in Google Maps. This is helpful because some panos are disconcertingly fish-eyed, causing vertigo as you swivel in the photo by swiping your mouse across it.

360Cities not only showcases and indexes panos, it offers tutorials about how to make your own. It invites photographers to contribute their work. 360Cities is now integrated into Google Earth in the gallery layer. All the panos are interesting; many are stunningly beautiful.

Map the Past with Historypin

HistorypinLondon’s “We Are What We Do” is a non-profit that aims to enable the public to help with environmental and social issues.

The point is to connect people and their stories across geography and generations. Libraries, schools and historical archives are encouraged to scan and upload old photos to create virtual “tours”of the past and collections of memories. Historypin plans to add the ability to play sound and videos soon.
