Technology can come to the rescue at D.C. events such as the October 30 Jon Stewart and Stephen Colbert Sanity rally – where huge crowds fueled by social media come together in a real place.
That’s according to Curt Westerphal of Digital Design & Imaging Service Inc., also known as AirPhotosLIVE.com. The Falls Church, Virginia firm was hired by CBS News to count heads at both the Comedy Central and Glenn Beck rallies. Curt got in touch after reading my Sanity rally followup in the Washington Post.
From a balloon tethered high above the Air and Space Museum, AirPhotosLIVE took pictures with an array of high-resolution cameras, combining the images with photos taken from atop the Washington Monument and a GeoEye satellite. In the same way a person looks down on a busy ant hill, these sophisticated eyes in the sky watch how people swarm and surge. Stunning photography and 3-D views of the Sanity rally can be seen on the Photosynth website.
“We are looking at patterns of movement and demand,” Curt wrote. “The crowd movement patterns we see from the air are valuable since they help transportation, security, first-responders and even Porta-Potty planners locate and track the flow of the crowd.” For instance, if the National Park Service used AirPhotosLIVE imaging, officials could see in nearly real time which subway stations were being overrun and let Metro know where to direct riders to less-crowded stations.
Soon, information could go directly to the crowd via their smart phones. We’re one inch away from having everyone there see the info,” Curt told me. “We already have a wireless downlink to our trailer. The issue is getting it out to social media. We could post it to a website right now. The limitations are really less technical and more political.”
That would be great if the cell phones actually worked, which they didn’t inside the Sanity rally. But, with enough planning, that problem can be solved, too. That is, if COWs roam the Mall. Cells On Wheels are mobile cell phone towers which temporarily stretch available bandwidth allowing phones to keep working. COWs were used successfully at the Obama inauguration.
Curt’s balloon also serves as a relay for walkie-talkie and 911 communications between emergency responders, even if they are on different frequencies. “The aerostat at 800 feet could allow a person at a distant station, say Greenbelt Metro, to talk to someone at the Reston Metro.”
But what happens if weather or something else grounds the amazing inflatable? “I joke about ‘one if by land, two if by sea’,” Westergard said in an email. “But two simple flag colors can tell a lot. Think hurricane warning flags or smoke signals. A flag at 500 feet can be seen from Tysons with binoculars. This city unfortunately may need that level of mass communication one day.”
