A 3.8 Billion-Pixel Tour Of Mount Everest

Photographer David Breashears of GlacierWorks was on All Things Considered Monday to talk about a new way of photographing the Himalayan region: By stitching together 400-plus images into one giant, zoomable, interactive image — or a "gigapan" containing more than a billion pixels.

He and his team just sent us something even cooler that they're currently working on: a Mount Everest you can explore, containing an estimated 3.8 billion pixels!

Here's how it works:

See those little green squares? Those are hot spots. Click one, and you'll zoom into that location. The square that's second up from the bottom, toward the left, for example: That will take you to a little village of tents — Everest base camp. Click on the tent, and you can go in. You'll see a photo exhibit that was mounted by Breashears there. And then, click on one of the photos, and you'll head back out to the mountain.

Breashears and his team allowed us to embed this teaser image on our site. But, he says, this barely scratches the surface of where the project is headed. "It's hardly even a demo," he tells me over the phone. "It's missing 99 percent of its functionality, which is audio and video and the ability to access other curated content."

When complete in a few months, this will serve as a completely interactive tour of Mount Everest. You will be able to go into the Tibetan monastery, get to know the sherpas who work with the GlacierWorks team, or learn more about glaciology and the history of climbing.

"You'll be able to choose, and it'll all be there in an image," says Breashears. "But the image starts the narrative."

The black-and-white image below shows the Kyetrak Glacier in the Himalayas photographed in 1921 by Maj. E.O. Wheeler/Royal Geographical Society. It's compared with a 2009 image by David Breashears/GlacierWorks.

"Rich interactive narrative," as Breashears calls it, is his specialty. And he insists that GlacierWorks — which he created to document changes to ice over time — is not about advocacy or activism. It's about education, he says. His goal is to provide photographs as tools to teachers and students, because in photos, "the change, or lack of change, is there, discernible and irrefutable."

Breashears started GlacierWorks in 2007. He began by pairing old photographs of the Himalayan region taken by early mountaineers and dating back to the early 1900s with current photographs. Layered on top of each other, the images are a stark testament to just how much has melted.

The black-and-white image of the East Rongbuk Glacier on the northern slope of Mount Everest was originally captured by Maj. E.O. Wheeler/Royal Geographical Society in 1921 — and is compared with a 2011 photograph taken by David Breashears/GlacierWorks.

Eventually, he explains, these "match photographs" will be integrated with the gigapan interactive. To shoot the gigapan, Breashears stood exactly where photographers stood decades ago and framed the new image in the same way as the original. That way, when you're exploring the modern image, you'll be able to peel it back and see how the ice has changed shape.

"The real struggle," says Breashears, "is that we're trying to show something that's happening in extreme slow motion. ... [When] you're looking at glaciers, you can sit there and stare at them for a long time and nothing happens. They don't talk to you; their stories are ones that you understand through science."

"The idea of connecting people with this environment, with this ice they're climbing on and this ice that's changing, is to bring a human element to it."

For most of us, after all, you have to see it to believe it.

Photo Project Tracks Climate Change On Everest

Filmmaker David Breashears has summited the world's highest peak five times. His latest project matches old photos of Mount Everest and its glaciers with new images to demonstrate how climate change is affecting the mountain. Melissa Block talks with Breashears about the GlacierWorks project.

ROBERT SIEGEL, HOST:

From NPR News, this is ALL THINGS CONSIDERED. I'm Robert Siegel.

MELISSA BLOCK, HOST:

And I'm Melissa Block.

Mount Everest is a symbol of excellence and of danger. The world's highest peak means success to mountaineers. And it's also, according to filmmaker David Breashears, a canary in the coalmine of climate change. Breashears has just returned from a trip to Nepal where he's been gathering extraordinary images of Everest's retreating glaciers.

I talked with him about one huge and majestic image taken this spring. It's posted on his GlacierWorks website. Compare earlier pictures taken decades back with this image, and you can see how the snow and ice have disappeared in the past 100 years.

DAVID BREASHEARS: It's, I think, almost 400 images taken with a 300-millimeter lens that are then stitched together. When you view them in the browser, allowing you that deep zoom capability.

BLOCK: Yeah, and it's a panoramic image. You can scan from right to left and get this amazing sweep of the Himalaya.

BREASHEARS: Yeah, it's just extraordinary and we're so excited by that image. I have myself climbed Everest five times and been to the mountain 15 times. And when I'm breathless at almost 18 or 19,000 feet recording these images, I have very little time to study the mountain and learn about it. And, of course, I can't focus my eyes as closely as that lens can.

So, as I sit there and examine that image and all its beauty and glory, I find things that I've never noticed before, especially as they relate to how climate change is affecting the mountain.

BLOCK: And we're talking about a gigapixel image. A gigapixel being...

BREASHEARS: A billion pixels. So I think this image has two or three billion pixels.

BLOCK: Well, this is what's amazing because I'm zooming in on this image and I keep zooming in closer and closer and closer. I feel like I'm practically inside the glacier itself. And you can see just incredible detail. It doesn't get blurry. It doesn't get out of the focus. You can see climbers - they look like tiny little specks but you can see their form climbing up this glacier.

BREASHEARS: Yeah, we can see climbers several miles away on the Lhotse face. Lhotse itself is over 28,000 feet high. And several thousand feet below its summit is Camp 3. And if you zoom in there, you can see not only the tents, but the little climbers - well, they're little in the picture - making their way up to camp and to the higher camp.

BLOCK: When you compare the images that you're shooting now of Mount Everest with images shot back in the '50s, as far back as the 1920s, do you also see simply just more exposed rock that the images that you're seeing from the Himalayas now? Or just that there's less white, it's more ground?

BREASHEARS: Yes, we see a lot less ice. We see a less snow cover. We see much more exposed rock in nearly all of the places we visited. In some regions in the west, a few of the glaciers are actually quite stable. But there are over 49,000 glaciers throughout the greater Himalayan region, and most of them are showing dramatic and accelerated melt rate.

BLOCK: I wonder if there is some risk in making these pictures, these images that makes the mountain seemed so approachable. You're zooming right in. It's like you're there and you almost think, you know, I could do that. I could go climb that.

BREASHEARS: You know, I often think about how the images that I've brought back from the years from Mount Everest, including the first live broadcast in 1983 to the "Everest" IMAX film and now this gigapixel imagery, I've often thought if that just makes the mountain seemed too accessible to people.

BLOCK: Yeah.

BREASHEARS: And I have realized that's the call of that mountain, the iconic presence it has in our lives, and the sense of achievement it provides people with, and the sense of kudos and the feather-in-the-cap reward you get when you return home, that that is the draw of that mountain. I can't make that mountain any more compelling than the fact that it's 29,028 feet high, the highest point on our planet. And if that isn't a calling card, I don't know what is.

BLOCK: David Breashears, thanks very much.

BREASHEARS: You're welcome. Thank you for the opportunity.

BLOCK: David Breashears is the founder of GlacierWorks, which is working to match historical photographs to show how the Himalayan landscape has changed.
