The ISGS’ Landsat photographic print archive is unique in a few important aspects. The 27 prints, which have acquisition dates between 1975-1979, date back to the two earliest Landsat satellite missions. Despite the comparably coarse ground spatial resolution, they portray the ground surface of Illinois as it appeared prior to widespread adoption of conservation tillage/no till agricultural practices in the mid-to-late 1980s. These subtle landscape features are no longer visible now that crop residue covers the land surface during much of the year.
Another unique aspect of the collection is that large format, high-quality photographic paper prints are no longer available from federal agencies, and while digital data are available, typical color ink-jet and laser printers are not able to render the imagery in the same level of quality.
Lastly, there was a concerted effort 15+ years ago by Goddard Space Flight Center and the U.S. Geological Survey to migrate decades-old magnetic tapes holding historic Landsat satellite digital data to a more permanent data format. While a large percentage of the data were recoverable, much was permanently lost, including some of the imagery that is part of the ISGS Landsat print archive. These aspects make the ISGS Landsat print archive an irreplaceable collection.”
“Landsat was the world’s first land remote sensing satellite. Landsat 1, originally ERTS (Earth Resources Technology Satellite) was launched in July 1972; and the seven follow-on Landsat satellites have provided continuous imaging of the earth’s land surface for nearly 43 years: http://landsat.usgs.gov/about_mission_history.php. The original MSS (Multispectral Scanner) instrument captured a 57 x 79 m (1.1 acres) ground area, considered quite coarse compared to modern-day imaging satellites (.41 x .41 m, or 1.8 ft2). Although later Landsat satellites carried higher resolution sensors, the legacy MSS instrument was retained for continuity and provided 57 x 79 m images of the earth’s land surface through 1999, a period of 27 years.
ISGS currently has a complete set of smaller prints and a partial set of larger prints. See details below:
