DARPA shows off 1.8-gigapixel surveillance drone that can spot a terrorist from 20,000 feet above

DARPA shows off 1.8-gigapixel surveillance drone that can spot a terrorist from 20,000 feet above | Emergent Digital Practices | Scoop.it

DARPA and the US Army have taken the wraps off ARGUS-IS, a 1.8-gigapixel video surveillance platform that can resolve details as small as six inches from an altitude of 20,000 feet (6km). ARGUS is by far the highest-resolution surveillance platform in the world, and probably the highest-resolution camera in the world, period.

 

ARGUS, which would be attached to some kind of unmanned UAV (such as the Predator) and flown at an altitude of around 20,000 feet, can observe an area of 25 square kilometers (10sqmi) at any one time. If ARGUS was hovering over New York City, it could observe half of Manhattan. Two ARGUS-equipped drones, and the US could keep an eye on the entirety of Manhattan, 24/7.

 

It is the definition of “observe” in this case that will blow your mind, though. With an imaging unit that totals 1.8 billion pixels, ARGUS captures video (12 fps) that is detailed enough to pick out birds flying through the sky, or a lost toddler wandering around. These 1.8 gigapixels are provided via 368 smaller sensors, which DARPA/BAE says are just 5-megapixel smartphone camera sensors. These 368 sensors are focused on the ground via four image-stabilized telescopic lenses.

 

ARGUS’s insane resolution is only half of the story, though. It isn’t all that hard to strap a bunch of sensors together, after all. The hard bit, according to the Lawrence Livermore National Laboratory (LLNL), is the processing of all that image data. 1.8 billion pixels, at 12 fps, generates on the order of 600 gigabits per second. This equates to around 6 petabytes — or 6,000 terabytes — of video data per day. From what we can gather, some of the processing is done within ARGUS (or the drone that carries it), but most of the processing is done on the ground, in near-real-time, using a beefy supercomputer. We’re not entirely sure how such massive amounts of data are transmitted wirelessly, unless DARPA is waiting for its 100Gbps wireless tech to come to fruition.

 

The software, called Persistics after the concept of persistent ISR — intelligence, surveillance, and reconnaissance — is tasked with identifying objects on the ground, and then tracking them indefinitely. As you can see in the video, Persistics draws a colored box around humans, cars, and other objects of interest. These objects are then tracked by the software — and as you can imagine, tracking thousands of moving objects across a 10-square-mile zone is a fairly intensive task. The end user can view up to 65 tracking windows at one time.

Assembling traces, or the conservation of net art by Annet Dekker

Assembling traces, or the conservation of net art by Annet Dekker | Emergent Digital Practices | Scoop.it
Net art is built and distributed through a complex, intricate, and interrelated system of networks that presents an assemblage of art, technology, politics, and social relations – all merged and related to form a variable entity. In the last decade a discussion on how to conserve net art emerged in museums of contemporary art. Nevertheless, many net art projects from the 1990s have long disappeared – their server payments lapsed, software was not kept up-to-date, or artists felt the concept was no longer appropriate in a changed context. The project mouchette.org is an exception in that the artist has kept the website up and running since it began. In this article I will show that net artworks are inherently assemblages that evolve over time. These works are distributed and ensured by networks of people; their continuation happens through multiple authors and caretakers. All together these actors signify and give meaning to the works. Therefore, instead of thinking of a ‘freeze frame’ the presentation and conservation of net art should focus on variability. This opens up different paths and options, making for conservation strategies akin to assembling traces.

Personal space can be a rare thing in overpopulated contemporary cities. Metro systems in cities like London, Tokyo and Hong Kong can be so overcrowded that you're forced to share that space with strangers. That's why Hong Kong-based artist Kathleen McDermott created a dress that automatically expands when someone gets too close.

20 Day Stranger is an iPhone app that reveals intimate, shared connections between two anonymous individuals. It's a mobile experience that exchanges one person's experience of the world with another's, while preserving anonymity on both sides.

For 20 days, you and a stranger will experience the world in your own way, together. You'll never know who it is or exactly where they are, but we hope it will reveal enough about someone to build your imagination of their life... and more broadly, the imagination of strangers everywhere.

Walking West -Colfax Ave

Walking West -Colfax Ave | Emergent Digital Practices | Scoop.it

New media artist Conor McGarrigle will walk Denver's Colfax Avenue, the longest continuous street in America, drawing a 26 mile line to be captured in a satellite photograph.

 

In his latest psychogeographic performance, which takes place on Friday April 11, McGarrigle will walk the entire 26.2 mile length of Denver's best known and most controversial street, from the eastern plains through the heart of downtown toward the west.

 

He will mark his route by drawing a line as he walks with the action captured from space by a commissioned high-resolution satellite photograph. The project will be the first artistic performance documented by satellite and will produce one of the largest drawings ever made.

 

The very act of walking in the city has become a marginalized practice in many American cities yet by walking we can experience the city itself, at a human pace, as a space of discovery and encounter. The symbolic act of walking Colfax Ave acts as a lens to focus discussion on the role of this street in the cultural, social, economic and political life of Denver and at a wider level the role of urban walking.

Digital Rubbish: A natural history of electronics

Digital Rubbish: A natural history of electronics | Emergent Digital Practices | Scoop.it

Digital Rubbish: A Natural History of Electronics describes the materiality of electronics from a unique perspective, examining the multiple forms of waste that electronics create as evidence of the resources, labor, and imaginaries that are bundled into these machines. By drawing on the material analysis developed by Walter Benjamin, this natural history method allows for an inquiry into electronics that focuses neither on technological progression nor on great inventors but rather considers the ways in which electronic technologies fail and decay. Ranging across studies of media and technology, as well as environments, geography, and design, Jennifer Gabrys pulls together the far-reaching material and cultural processes that enable the making and breaking of these technologies.
