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.

Why Big Data Missed the Early Warning Signs of Ebola | Foreign Policy

Why Big Data Missed the Early Warning Signs of Ebola | Foreign Policy | Emergent Digital Practices | Scoop.it

Hint: Ils ne parlent pas le français.

 

The U.S. government's Intelligence Advanced Research Projects Activity (IARPA), which helps fund HealthMap, has used this success story as evidence that the approaches used in its Open Source Indicators program can indeed "beat the news" and provide the earliest warnings of impending disease outbreaks and conflict.

It's an inspirational story that is a common refrain in the big data world -- sophisticated computer algorithms sift through millions of data points and divine hidden patterns indicating a previously unrecognized outbreak that was then used to alert unsuspecting health authorities and government officials.  The problem is that this story isn't quite true:

By the time HealthMap monitored its very first report, the Guinean government had actually already announced the outbreak and notified the WHO.

The Impact of the Internet on Society: A Global Perspective - OpenMind

The Internet is the decisive technology of the Information Age, as the electrical engine was the vector of technological transformation of the Industrial Age. This global network of computer networks, largely based nowadays on platforms of wireless communication, provides ubiquitous capacity of multimodal, interactive communication in chosen time, transcending space. The Internet is not really a new technology: its ancestor, the Arpanet, was first deployed in 1969 (Abbate 1999). But it was in the 1990s when it was privatized and released from the control of the U.S. Department of Commerce that it diffused around the world at extraordinary speed: in 1996 the first survey of Internet users counted about 40 million; in 2013 they are over 2.5 billion, with China accounting for the largest number of Internet users. Furthermore, for some time the spread of the Internet was limited by the difficulty to lay out land-based telecommunications infrastructure in the emerging countries. This has changed with the explosion of wireless communication in the early twenty-first century. Indeed, in 1991, there were about 16 million subscribers of wireless devices in the world, in 2013 they are close to 7 billion (in a planet of 7.7 billion human beings). Counting on the family and village uses of mobile phones, and taking into consideration the limited use of these devices among children under five years of age, we can say that humankind is now almost entirely connected, albeit with great levels of inequality in the bandwidth as well as in the efficiency and price of the service.

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.

TBD Catalog

TBD Catalog | Emergent Digital Practices | Scoop.it

Imagine a print distribution network with cloud-connected street vending/printer boxes. Overnight, algorithms API-shazam content for those boxes to print. Printed stuff piles up every night in those boxes, including cheap copies of a location-specific, regionally tuned catalog selling stuff for your normal, ordinary everyday life. This is TBD Catalog. It's an awkward attempt by an awkward business to attract more eyeballs and sell more stuff in a near future where the screen world has become so saturated and overrun that other mediums, like paper and street vending boxes, have become a natural spillover. It's a printed catalog you ritually pick up every morning to browse on your mostly boring, everyday ordinary driverless commute. You may even look forward to it, the way you look forward today to the free daily commuter news, or the Skymall catalog, or an entertaining bit of junk mail.

The semantic production of space: pervasive computing and the urban landscape by Matthew J Kelley | Env&Plan A

This paper suggests that as pervasive computing technologies have gained purchase in urban space they have also become more implicitly blended with everyday life and more contingent on information that is inductively compiled from Internet-based data services. It is argued that existing theorizations of the technologically mediated production of urban must engage with the increasingly implicit nature of informational transactions as well as the emergent semantic structuring of information. Drawing on examples of ongoing pervasive computing projects, implicit computing procedures are explored in relation to the mediation of everyday urban life. Literatures from computing science and geographical theory are brought into conversation in order to examine the consequences of a convergence between implicit pervasive technologies and the spaces of everyday life.  ....

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.
