This is a satellite image data product made available from the 1995 declassification of intelligence imagery acquired by the first generation of United States photo-reconnaissance satellites, including the systems code-named CORONA, ARGON and LANYARD. More than 860,000 images of the Earth's surface, collected between 1960 and 1972 have been declassified. The images were used to produce maps and charts for the Department of Defense and other Federal Government mapping programs. Nearly all of the imagery from these systems was collected using black and white film. There is a very limited amount of infrared film and high definition colour aerial film that was tested as part of the KH-4B missions and yielded poor spatial resolution performance. The original film is being preserved by the National Archives and Records Administration (NARA) and is stored at the National Archives at College Park, MD. The US Geological Survey (USGS) originally delivered these images as negatives and prints to customers, but now USGS offers them as scanned images in *.tiff file formats. The images are not geo-referenced and require a Geographical Information System (GIS) or image processing package to achieve this. This CORONA image dataset was captured as part of the KH-4B mission which photographed the earth's surface from September 1967 to May 1972. The ground resolution for these images is six feet (1.8 metres). This image is identified as DS1107-2154DA071, which is coded to provide the following information: DS = Dataset Name (2 characters) MMMM = Revolution (4 characters) C = Camera Type (1 character) FFF = Frame number (3 characters) This image file is named <rectify1107_2154da_71c_c2.tif> and is one of eight image files cropped and extracted from the original file. This was done to improve spatial accuracy, during geo-referencing of each image, and reduce file size. The original image covers an area which spans about 275 kilometres in length and 21 kilometres in width. TThe photo extends across an area, which follows along the Syrian/Turkish border and extends east into the Sirnak Province of Turkey. The image starts just east of the Ras al Ayn settlement in Syria and extends east towards the settlement of Beytussebap, Turkey. Beytussebap is about 85km east of the River Tigris. Neither Ras al Ayn or Beytussebap can be seen on the image, but both are within 10km to the west and east respectively. This image covers an area extending from the River Tigris, west, to Lake Baraj in Turkey. As this image was captured during the summer month of August in 1969, there is very little cloud cover present; ground visibility is close to 100 percent. This image has been primarily used as part of research to locate and map archaeological sites (Tells) in this part of the Jazira region of Syria. The image also provides an important snapshot of the northern Jazira landscape in 1969. Landscape features and settlements in the region can also be mapped and compared with those from images captured recently to track and compare changes to land-use and settlement patterns in the region. This CORONA image dataset was captured as part of the KH-4B mission which photographed the earth's surface from September 1967 to May 1972. This image is identified as DS1107-2154DA071.Original CORONA image was opened in Adobe Photoshop and cropped into eight segments, then saved as separate files to reduce file size and improve spatial accuracy. Each image segment was cropped again to remove the dark surround and label from original film negative; USGS policy was to scan the entire photo negative. The dark surround contributes significantly to the file size; the removal of this reduces the file size and allows for displaying and joining adjacent images to form a contiguous area. Each CORONA image was subsequently opened in ArcGIS and geo-referenced using ground control points. Landsat images were used as cross-reference sources for acquiring co-ordinates to geo-reference the image. The number of control points added to the image varied and depended on identifiable surface features. When possible, road intersections and setlltements were used, though fewer existed when this 1969 image was captured; much of the area covered represents rural landscape. River and wadi confluences and meanders were also located and used for ground control points, though wadis are more prominent in this semi-arid region. This CORONA image extends across an upland area on the Turkish side between the River Tigris and Lake Baraj to the west. Control points were established at settlements found along the River Tigris and Lake Baraj. Aerial or Satellite Imagery.
