 (New York City - 1966) |
Product DescriptionThe U.S. Geological Survey (USGS) EROS Data Center (EDC) has archived thousands of rolls of film containing several million frames of historical aerial and satellite photographs dating back to the 1930's gathered from various Federal agencies. This archive includes the rather well known, often utilized NHAP and NAPP film, but the largest portion of this archive consists of original film acquired in support of the USGS 1:24,000 topographic quadrangle map series, taken during the 1940s through the 1970s. Most of this photography is reasonably large scale to support the production of the quadrangle maps.
The USGS EROS Data Center has implemented a high-resolution digitally scanned product. The high-resolution files are created at approximately 1200 dpi with an output image size of around nine inches square. The file sizes are approximately 120 megabytes for black and white images and 360 megabytes for color images and are stored in TIFF format. The high-resolution files are produced on either a Zeiss Precision Scanner using a PHODIS Photogrammetric Image Processing System or a Leica Geosystems DSW600 Digital Scanning Workstation. At this time, only 9x9 inch and smaller original film is available for scanning.
