Where in the World?

Tom James @ 18-06-2008

Finding photos in old books and not having any clue as to the locations they depict could become yet Earthanother mild annoyance thrown into the furnace of perpetual progress.

Comp-sci boffins at Carnegie-Mellon University have developed a system called IM2GPS that can identify the probable geographic location of a given image. From the abstract of the paper:

In this paper, we propose a simple algorithm for estimating a distribution over geographic locations from a single image using a purely data-driven scene matching approach. For this task, we will leverage a dataset of over 6 million GPS-tagged images from the Internet. We represent the estimated image location as a probability distribution over the Earth’s surface. We quantitatively evaluate our approach in several geolocation tasks and demonstrate encouraging performance (up to 30 times better than chance). We show that geolocation estimates can provide the basis for numerous other image understanding tasks such as population density estimation, land cover estimation or urban/rural classification.

The trend is towards every piece of data being tagged with a location: here we see a way of legacyqrcode information (old photos) being given a “probable geographic location” without having originally being created with a time/GPS location stamp. It would still only be a general guess as to a geographic area, but it is better than nothing.

This is part of a more general trend towards what Bruce Sterling calls Spimes. From the Man himself:

The most important thing to know about Spimes is that they are precisely located in space and time. They have histories. They are recorded, tracked, inventoried, and always associated with a story.

In the case of IM2GPS it is the data itself that is being recorded and tracked, and potentially the objects the data describes (the objects in the photos) which connects with another loosely related concept: the panopticon. Imagine if you combined IM2GPS technology with facial recognition software and put CCTV archives through this kind of process. You could essentially Spimify the population retrospectively!

Hysterically delusional paranoia aside this is a fascinating development. Read the paper in full (pdf), it’s well worth it.

Manufacturing2.0 – Ponoko’s personal manufacturing community

Paul Raven @ 19-09-2007

When Bruce Sterling spots something and considers it worthy of note, you can assume he knows what he’s on about – especially if it’s connected to his spimes idea.

But it doesn’t take a genius to see the huge disruptive potential of the "personal manufacturing network" business model behind Ponoko. I’ll simply quote their site, because I couldn’t put it more succinctly than this:

"Ponoko is the world’s first personal manufacturing platform. It’s the online space for a community of creators and consumers to use a global network of digital manufacturing hardware to co-create, make and trade individualized product ideas on demand.

The ponoko.com marketplace connects creators, consumers, digital manufacturing hardware and service providers to promote, make and trade products on Ponoko and social networking websites."

Poke around the site, and think about it. One of the few things I’ve seen recently where the tired cliche "this could change everything" really does apply.
