Google has launched a competitor or counterpart to Microsoft's Photosynth
, which employs user-contributed photos of much-photographed sites to supplement the street-level view in an immersive way. Google's offering is called simply Navigate through User Photos
, and unlike Photosynth — which requires Sliverlight and therefore is not available on Linux — is implemented in Flash. This YouTube video (also embedded at the link above) offers a quick tour of the new feature
, which can use photos uploaded to Panoramico, Flickr, and Picasa.
