About iWitness, from the iWitness FAQ:
Q: What is iWitness?
A: iWitness is a free, web-based software tool that makes it easy for people to explore social media content by time and place.
Q: How does it work?
A: iWitness scans social media services for content that a user has attached a location to. Any content without a location attached to it does not show up in iWitness.
Q: What social media services does iWitness support?
A: The initial release of iWitness scans Twitter and Flickr. It can also show photos and videos posted to Twitter that are hosted on the following services:
Photos: Twitter, Instagram, Twitpic, Twitgoo, Lockerz
Videos: YouTube, Twitvid, Vimeo
Q: What about Facebook? I love Facebook!
A: We love Facebook too. But Facebook doesn’t let us access the location associated with a piece of content. We hope they will in the future. Fortunately, iWitness is an open-source tool, meaning anyone can modify it or extend it to support new services.
Q: What browsers does iWitness work on? Can I use it on my phone or tablet?
A: iWitness works with WebKit-based browsers such as Google Chrome or Safari. You can use it on an iPad, but it’s not designed to work on the small screens of mobile phones.
