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. Archaeologist Sarah Parcak uses satellite images to identify buried sites. U-2 spy plane photos (left, October 1959) offer imagery at a much higher resolution than CORONA spy satellite images (right, May 1968). 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. 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. Surely newer technologies, they think, provide the best photos? Sentinel-2 is the start of a new and exciting era… 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. 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 … This image, taken by U-2 mission 8648, reveals Iraqi Marsh villages as they appeared in October 1959. Emily Hammer. 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. 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. Satellite imagery, and specifically CORONA, is now of common use in archaeology. Satellite imagery gives us a new tool in the global fight to protect our cultural heritage. Then, partway through the roll, an intensely white negative frame came into view, brightening the whole room. Stereo IKONOS Satellite Image Data Utilized to Support 3D Terrain Visualization for Mt. As satellite imaging—natural-color, false-color, and radar—has evolved and became more accessible, a … That means we have a much broader view, making it easier to recognize ground features. Professional archaeologists will still consult satellite imagery… In ‘Archaeology from Space,’ Sarah Parcak takes readers on a lively tour of the past, and archaeology of the 21st century. In the 1990s, then-President Saddam Hussein systematically drained what was left, forcing marsh dwellers to abandon an ancient way of life. Before looking at satellite imagery, archaeologists pinpoint potential sites by cross-referencing ancient and modern maps to examine topographical changes over time. Among these rural and urban scenes, a careful viewer can also find traces of ancient and historical settlements and land use. For example, we found that mission 8648 departed the İncirlik Air Base at Adana, Turkey, on October 30, 1959. Now anyone with access to the Internet can do the same through Parcak’s new crowdsourcing platform called … 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. I was stunned by the sheer number of structures and the clarity of the desert kites in the images. Copyright © 2001-2017 Satellite Imaging Corporation. Become a space archaeologist and document threats to ancient sites. In archaeology, the primary use of satellite images … 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. But within this landscape, human hands had moved hundreds of stones into distinctive shapes. Because, in the end, she says, “When we dig, we are digging for people, not things.” Image courtesy of DigitalGlobe. CORONA photos only have a resolution of about 2 meters per pixel, too grainy to see anything but the largest walls of ancient buildings. 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. Emily Hammer. By Emily Hammer / 21 Feb 2020. Now, she … But for archaeology … Archaeology, in many ways, is a race against time. Help … U-2 spy plane photos (left, October 1959) offer imagery at a much higher resolution than CORONA spy satellite images (right, May 1968). 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. Please choose one to learn more. 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… Satellite imagery can be used as a methodological procedure for detecting, acquire inventory and prioritizing surface and shallow-depth archeological information in a rapid, accurate, and quantified manner. A lot of work has focused, for example, on images from the United States’ first-ever spy satellite program, CORONA, designed to image Cold War hotspots in a less dangerous way than from a U-2 airplane. Each station therefore receives the images … “Traditional archaeology wasn’t going to work for me to answer the questions I had,” he said. Get a complimentary consultation today. But buried within the film rolls were high-resolution photos of historical, ethnographic, and archaeological sites and landscapes. The patterns created by such changes—such as long straight lines—are only noticeable when viewed from afar. 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. Why Do We Keep Using the Word “Caucasian”? 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. In 1981, he joined the small group of programmers at Stennis who were learning to interpret satellite images even … 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. It would be tedious if it weren’t for the fact that the images are so interesting and occasionally beautiful. It’s also about … We worked with the available film generated by all Middle East missions for which the National Archives has declassified film. Emily Hammer. 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. Clusters of dwelling foundations or animal corrals dotted the regions around the kites and wheels and also more empty areas. Five thousand years ago, a grand city in the deserts of Oman … In a darkened room of the U.S. National Archives, we stood over a light table, a special backlit surface for viewing film. 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. Is the Term “People of Color” Acceptable. Right now, our index only covers the Middle East because we happen to actively conduct archaeological work there. These images come from a special collection of footage. The buried remains of ancient canals, fields, roads, or paths sometimes cause differences in the soils’ moisture, salinity, or chemistry. Top Tier Worldwide Data European Space Agency Registration Required. These images both show the ancient Mesopotamian city of Ur in present-day Iraq. They aimed to cover places of interest for military intelligence such as foreign bases, airfields, and potential nuclear weapons facilities. Satellite images and GIS have become increasingly important tools for archaeologists, as these systems link information to precisely calibrated physical locations, and integrate information drawn from multiple sources. 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. The rate of those transformations has accelerated in recent decades. Discover what's possible. Courtesy of Sarah Parcak Sarah Parcak is a space archaeologist. Emily Hammer. 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 … Sarah Helen Parcak is an American archaeologist, Egyptologist, and remote sensing expert, who has used satellite imaging to identify potential archaeological sites in Egypt, Rome, and elsewhere in the former … From satellite images and digital elevation data the team of space archaeologists will anchor and standardize reference points using Global Positioning Systems (GPS), first developed by the U.S. … 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. CORONA, as it produces two images of the same spot (afterward and forward), allows for … 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. Old aerial images allow archaeologists to travel back in time. Satellite images and GIS have become increasingly important tools for archaeologists, as these systems link information to precisely calibrated physical locations, and integrate information drawn from multiple sources. But for archaeology and history, the newest images are not always the best ones. U-2 spy plane photography shows ancient sites such as “desert kites,” mass-kill traps used for hunting gazelle (eastern Jordan, January 1960). 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. Even though satellite imagery produces higher resolution, it has the same limitation as its predecessor. Archaeology is a messy business. Satellite imagery has been productively used to solve a wide variety of problems in different domains--from predicting crop yields for commodity futures trading, to assessing environmental conditions for disaster mitigation. 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. Take a few steps back and a meaningless cluster of colors becomes a woman with a parasol on a riverbank. From the safety of space, CORONA cameras captured many high-resolution photos from 1967–1972. Many people wonder why we don’t just look at modern satellite imagery. We geo-reference each frame in digital mapping software to geometrically correct it and give it real-world coordinates. These changes in turn affect plant growth. Emily Hammer. You’ll only see what the eye can detect,” says McManamon. This process creates an image that we can use to map the particular place that it happens to cover. Over four years of work, we have processed a few hundred of these frames for our own research projects. Since 2015 summer … Now there’s a new way to search, with no shovels needed. These features weren’t previously unknown to archaeologists. The U.S. government declassified many U-2 images in 1997, making them freely available to researchers and the public. 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 … 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. The United States satellite images displayed are infrared (IR) images. Today’s Image of the Day includes excerpts from our recent feature: Peering Through the Sands of Time. It isn’t a new idea for archaeologists and human ecologists to use historical aerial and satellite images. But the island villages, woven reed huts, networks of boat paths, and expansive reed forests that sustained that way of life remain preserved in U-2 photos. Satellite imagery is a powerful tool. Sign up for our newsletter with new stories delivered to your inbox every Friday. The total number of U-2 missions is unknown but must be in the hundreds. The region today is sparsely inhabited, but nearly every negative over hundreds of frames showed dozens of features evidencing earlier human activity. This imagery also has limitations. 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.
