Images taken from planes or satellites are distorted because the lens never has a perfectly vertical perspective. Sarah Parcak is a space archaeologist, who uses satellite images to locate hidden ancient sites around the world, such as ancient Egypt, ... Archaeology is all about documenting a site. Is the Term “People of Color” Acceptable. Professional archaeologists will still consult satellite imagery… We matched this tracking film to modern satellite imagery to accurately reconstruct the path of the U-2 planes’ missions. However, the geographic coordinates in these documents were not very accurate, and some missions did not have declassified coordinates at all. Filed with the state of North Carolina on March 26th, 2013, the Satellite Archaeology Foundation, Inc. is a nonprofit corporation. In the past four years, my archaeologist colleague Jason Ur at Harvard University and I (a landscape archaeologist) have worked to make this complex photo archive accessible to other researchers and to illustrate its importance for history and anthropology. Emily Hammer. Satellite imagery—as many people know from Google Earth—has increased in resolution in recent years, allowing us to see finer details when we look at our neighborhoods and parks from an aerial view. With the 2016 TED Prize, Sarah Parcak has built a citizen science platform for … In archaeology, the primary use of satellite images … They aimed to cover places of interest for military intelligence such as foreign bases, airfields, and potential nuclear weapons facilities. U-2 spy plane photography shows ancient sites such as “desert kites,” mass-kill traps used for hunting gazelle (eastern Jordan, January 1960). Now anyone with access to the Internet can do the same through Parcak’s new crowdsourcing platform called … Mission 8648 photos also show ethnographically important environments and communities that have since totally disappeared: most significantly, the drained marshes of southern Iraq and hundreds of Marsh Arab villages within them. Archaeology is going digital to harness the power of Big Data ... Today: archaeologists are using drones and satellite imagery, among other tools, to build large online datasets with an eye … By Emily Hammer / 21 Feb 2020. Emily Hammer. View article on Stereo IKONOS Satellite Image Data Utilized to Support 3D Terrain Visualization for Mt. For example, we found that mission 8648 departed the İncirlik Air Base at Adana, Turkey, on October 30, 1959. Ur invited me to take a look at the images, which can approach a resolution of 30–50 centimeters per pixel, comparable to or greater than the resolution of most of the best imagery on Google Earth today. We worked with the available film generated by all Middle East missions for which the National Archives has declassified film. Sign up for our newsletter with new stories delivered to your inbox every Friday. The region today is sparsely inhabited, but nearly every negative over hundreds of frames showed dozens of features evidencing earlier human activity. Satellite Imaging Corporation is an official Value Added Reseller (VAR) of imaging and geospatial data products for: Satellite imagery can be applied within many industries. Archaeology / History / Politics / War, An editorially independent magazine of the Wenner‑Gren Foundation for Anthropological ResearchPublished in partnership with the University of Chicago Press, Spy Plane Photos Open Windows Into Ancient Worlds. These features weren’t previously unknown to archaeologists. It flew over western Syria, then over the desert to the Turkish border at Qamishli. The pilot turned east to visit Iraqi cities, made an extended detour south to Riyadh in Saudi Arabia, then returned to western Iraq. The mission of the Satellite Archaeology Foundation, Inc. is to research, … Space Satellite Archaeology Remote sensing from space In late May, 2011, news reports began to circulate describing how images of lost, undiscovered or misunderstood archaeological sites in Egypt … I was stunned by the sheer number of structures and the clarity of the desert kites in the images. Humans are continually transforming the earth’s surface, erasing traces of the past. If a CIA index of U-2 missions exists, it has not been declassified. Nineveh (in modern Mosul, Iraq) and Raqqa (in Syria) have suffered over the last decades in the face of urban development, and, since 2014, from deliberate acts of destruction by the Islamic State. Become a space archaeologist and document threats to ancient sites. GlobalXplorer° is an online platform that uses the power of the crowd to analyze the incredible wealth of satellite images currently available to archaeologists. That means we have a much broader view, making it easier to recognize ground features. U-2 spy plane photography shows ancient sites such as “desert kites,” mass-kill traps used for hunting gazelle (eastern Jordan, January 1960). Using a light table, landscape archaeologist Emily Hammer (the author) prepares to photograph U-2 negatives at the National Archives’ Aerial Film Section. In this short talk, TED Fellow Sarah Parcak introduces the field of "space archaeology" -- using satellite images to search for clues to the lost sites of past civilizations. They transport us to the mid-20th century, before urban expansion, development, and agricultural intensification wiped away the surface traces of ancient communities, many of which had survived for millennia. Stereo IKONOS Satellite Image Data Utilized to Support 3D Terrain Visualization for Mt. Using a light table, landscape archaeologist Emily Hammer (the author) prepares to photograph U-2 negatives at the National Archives’ Aerial Film Section. Welcome to the 21st-century world of space archaeology, in which culturally important ruins can be spotted and decoded via high-resolution images captured by Earth-orbiting satellites. Black-and-white negatives offered a bird’s-eye view of sinuous rivers lined with date palm tree gardens; villages ringed by agricultural fields; the occasional city, crowded with houses, markets, and mosques; and vast tracks of barren steppe-desert punctuated by dirt paths, isolated sheepfolds, or remote air strips. S atellite imagery—as many people know from Google Earth—has increased in resolution in recent years, allowing us to see finer details when we look at our neighborhoods and parks from an aerial view. Throughout the almost nine-hour journey, the plane flew close to 7,000 km and captured 5,053 frames in 39 rolls of film, plus 1,006 frames from the tracking camera. You’ll only see what the eye can detect,” says McManamon. In addition, if we want to find U-2 frames covering a particular place, we have to generate a spatial index, which requires additional work. We believe the project exemplifies how open-access archival data from the U.S. government can benefit the public and researchers across disciplines—historians, environmental scientists, archaeologists, ethnographers, and more. “Satellite imagery is still a photo. Why Do We Keep Using the Word “Caucasian”? These images compare Raqqa, Syria, in January 1960 (above) as taken by a U-2 spy plane and in July 2016 (below) as captured by the DigitalGlobe GeoEye-1 satellite. An observer can see things from the air that might not be obvious from the ground. Archaeologist Sarah Parcak uses satellite images to identify buried sites. Clusters of dwelling foundations or animal corrals dotted the regions around the kites and wheels and also more empty areas. For broader audiences, the photos provide a fascinating historical look at the Middle East—showing, for example, Old Aleppo long before the massive destruction wrought in the Syrian Civil War. These images both show the ancient Mesopotamian city of Ur in present-day Iraq. Discover what's possible. Google Earth, software that uses high resolution satellite images of the entire planet to allow the user to get an incredible moving aerial view of our world, has stimulated some serious applications in archaeology--and seriously good fun for fans of archaeology… Help … Further, some parts of the Middle East had experienced so much development by the late 1960s that many archaeological surface traces had already been erased. It’s also about … Copyright © 2001-2017 Satellite Imaging Corporation. Emily Hammer. THE LOST CITY OF IRAM/UBAR. Courtesy of Sarah Parcak Sarah Parcak is a space archaeologist. Archaeology Is Having a Great Century So Far, The Race to Recover South America’s Ancient Past, Finding Calm—and Connection—in Coffee Rituals. This process creates an image that we can use to map the particular place that it happens to cover. Since 2015 summer … Archaeologists have long pined for a bird’s-eye view like this, deploying hot air balloons, kites, helicopters, powered parachutes and blimps to snap pictures of their sites. Ararat Anomaly in Turkey. In 1981, he joined the small group of programmers at Stennis who were learning to interpret satellite images even … This imagery also has limitations. Sarah Parcak is a space archaeologist, who uses satellite images to locate hidden ancient sites around the world, such as ancient Egypt, ... Archaeology is all about documenting a site. In May 2019, we finally published our online, interactive guide for U-2 images of the Middle East, as well as a how-to guide for reproducing and working with the images. Old aerial images allow archaeologists to travel back in time. The work in the archives is cumbersome sometimes. The usefulness of satellite imagery for identifying and analyzing archaeological sites was recognized from the early days of aviation and the imagery is now available from an array high resolution satellite sensors that provide even greater potential for investigating archaeological sites. In ‘Archaeology from Space,’ Sarah Parcak takes readers on a lively tour of the past, and archaeology of the 21st century. Thanks to the U-2 program, anthropologists have an exciting new source of historical data on archaeological sites and landscapes—as well as the settlement and land-use patterns of 20th-century communities whose ways of life have since disappeared. We geo-reference each frame in digital mapping software to geometrically correct it and give it real-world coordinates. Today ancient Ur is in the middle of the desert, but U-2 photos show paleochannels of the Euphrates River surrounding the city—features that are no longer visible due to the massive expansion of the adjacent Tallil Air Base. Satellite imagery gives us a new tool in the global fight to protect our cultural heritage. Get a complimentary consultation today. Scholars often liken it to the result of stepping away from the blobs of paint in an impressionist artwork. But for archaeology … Each station therefore receives the images … A digital elevation model can be used to closely examine various terrain attributes, their influence on the movement of soil and nutrients, as well as the resulting effect on forest, plant, and wildlife productivity and distribution. We first tried searching CREST, the CIA’s database of declassified records, for documents concerning U-2 missions. Now there’s a new way to search, with no shovels needed. CORONA, as it produces two images of the same spot (afterward and forward), allows for … In a darkened room of the U.S. National Archives, we stood over a light table, a special backlit surface for viewing film. Archaeology is a messy business. It would be tedious if it weren’t for the fact that the images are so interesting and occasionally beautiful. The United States satellite images displayed are infrared (IR) images. The U.S. government declassified many U-2 images in 1997, making them freely available to researchers and the public. The patterns created by such changes—such as long straight lines—are only noticeable when viewed from afar. These changes in turn affect plant growth. The buried remains of ancient canals, fields, roads, or paths sometimes cause differences in the soils’ moisture, salinity, or chemistry. Emily Hammer. Our gloved hands slowly turned heavy metal rolls of 9.5-inch-wide film, unspooling our way back in time to the Middle East of the late 1950s and early 1960s. When we saw the amazing quality of the photos, we knew that it would be worth the detective work it would take to build a systematic index. We unspool hundreds of meters of film over a light table, identify frames from sites already known to be of archaeological interest, photograph the negatives in pieces using a 100-mm macro lens, and then stitch them together and invert them in Photoshop. I have worked with historical imagery throughout my career and have always wished for older, more detailed imagery than what CORONA could offer. Now, she … She uses satellite imagery to track looted ancient burial sites and find pyramids hidden under Egyptian cities. In the 1990s, then-President Saddam Hussein systematically drained what was left, forcing marsh dwellers to abandon an ancient way of life. To generate our own spatial index, we turned to skinny 2.75-inch rolls of “tracking film” captured by a second camera on the U-2 planes. In the late 1950s, U-2 spy planes flew at around 70,000 feet over Cold War hotspots in Europe and Asia, capturing images that could show details as small as a person. Satellite archaeology is a non-invasive method for mapping and monitoring potential archaeological sites in an ever changing world that faces issues such as urbanization, looting, and groundwater pollution … CORONA photos only have a resolution of about 2 meters per pixel, too grainy to see anything but the largest walls of ancient buildings. The very first film roll I browsed in my initial trip to the archives in 2015 began with the usual rivers, steppes, and towns in grayscale. Even though satellite imagery produces higher resolution, it has the same limitation as its predecessor. Over four years of work, we have processed a few hundred of these frames for our own research projects. As satellite imaging—natural-color, false-color, and radar—has evolved and became more accessible, a … This image, taken by U-2 mission 8648, reveals Iraqi Marsh villages as they appeared in October 1959. In 1995, then-President Bill Clinton declassified CORONA imagery and the images have subsequently led to the discovery of many fascinating archaeological features in the Middle East, such as 4,500-year-old road networks in northern Syria and paleochannels of rivers and canals modified over thousands of years in Iraq. Many people wonder why we don’t just look at modern satellite imagery. Satellite imagery is a powerful tool. The usefulness of satellite imagery for identifying and analyzing archae… The scale of this project is immense—both in terms of the work that we have already done and future work that others could do. Please choose one to learn more. Now, explorer Sarah Parcak is taking her groundbreaking space archaeology work to Peru with the launch of GlobalXplorer°, a new and cutting-edge platform that empowers citizen scientists around the world … U-2 spy plane photos (left, October 1959) offer imagery at a much higher resolution than CORONA spy satellite images (right, May 1968). Top Tier Worldwide Data European Space Agency Registration Required. U-2 spy plane photos (left, October 1959) offer imagery at a much higher resolution than CORONA spy satellite images (right, May 1968). There was no way to access the images digitally, nor could people know where geographically each roll of film was taken or highlight the particularly interesting frames. With the turn of the spool, I was suddenly flying over the black basalt desert of the eastern panhandle of Jordan. “Traditional archaeology wasn’t going to work for me to answer the questions I had,” he said. Archaeology, in many ways, is a race against time. As I turn the spool of a film roll, there is a sense of exploration and discovery: I can visually re-create the pilot’s journey. Ur’s findings even inspired an exhibition, “Spying on the Past: Declassified Satellite Images and Archaeology,” at Harvard’s Peabody Museum of Archaeology and Ethnology in 2011. This image, taken by U-2 mission 8648, reveals Iraqi Marsh villages as they appeared in October 1959. But for archaeology and history, the newest images are not always the best ones. But our published methods could be used by others to piece together indexes for other regions covered by the U-2 program, especially formerly Soviet Eastern Europe, the formerly Soviet Central Asian republics, and China. The negatives’ blinding brightness was caused by mesmerizing geological patterns: the desert’s dominant surface rock formations are dark, marbled by bands of lighter sediment deposits. The total number of U-2 missions is unknown but must be in the hundreds. The station's antenna points toward the satellite and tracks it for as long as it can until it moves out of range. To work with U-2 images, we first have to order film rolls from the National Archives’ “Ice Cube” preservation facility in Lenexa, Kansas, for delivery to the Aerial Film Section in College Park, Maryland. All rights reserved. Among these rural and urban scenes, a careful viewer can also find traces of ancient and historical settlements and land use. We hope that the online resources we have created will enable other anthropologists and historians to search the U-2 photo archives for images relevant to their own research projects. Sentinel-2 is the start of a new and exciting era… Today’s Image of the Day includes excerpts from our recent feature: Peering Through the Sands of Time. Unlike the main camera, which offers high-resolution images over stretches of the flight where it was activated by the pilot, tracking frames show low-resolution, horizon-to-horizon views under the plane throughout the entire flight. Decades-old photography from the U-2 spy program now offers a time machine to see traces of the historical and ancient past. In late 2012, Jason Ur met Lin Xu, a digital imaging expert who had gone to the National Archives to hunt down U-2 images of his hometown in China. Right now, our index only covers the Middle East because we happen to actively conduct archaeological work there. Vegetation in the shallow but possibly moister soils above an old, buried stone wall, for example, may be thicker or thinner than plants just to the side in deeper, better-draining soils. Then, partway through the roll, an intensely white negative frame came into view, brightening the whole room. Ararat Anomaly in Turkey, <1m Stereo IKONOS Satellite Image Data and 5m DEM, (Image Copyright © DigitalGlobe and Processed by Satellite Imaging Corporation). These images both show the ancient Mesopotamian city of Ur in present-day Iraq. Just these 11 missions generated 357 rolls of film holding 46,561 frames. These images come from a special collection of footage. But having so many high-resolution photos from so long ago and over such a broad area is a unique resource. From the 1970s onward, these marshes progressively shrank as hydroelectric dams impounded the Tigris and Euphrates floodwaters that once sustained them. SIC provides specialized image processing technique by color balancing and utilizing the correct band combinations for Normalized Difference Vegetation Index (NDVI) mapping technique, our experienced imaging and GIS mapping team will isolate the terrain features and geological information needed for the correct analysis of your research project.
