Until 1992, there was no digital archive for DMSP-OLS data. Air Force meteorologists did their analysis using visible and thermal band film strips. The National Snow and Ice Data Center maintained an archive for OLS film from 1972-1992 through a cooperative institute with NOAA. In 1992, a digital archive for the OLS data was established at the NOAA National Geophysical Data Center (NGDC). In 1996, NGDC had the film archive shipped to the Federal Records Center at the Denver Federal Center due to storage limitations. The film is slowly decaying and the data are no longer readily accessible. Quantitative use of the data has always been limited due to the difficulties in converting to a digital format. Access to the data has been extremely limited. completed DMSP Data Manager DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce 303.497.3053 (303) 497-6513 E/GC2 325 Broadway Boulder CO 80305 USA ngdc.dmsp@noaa.gov 7:30 - 4:30 Mountain Contact Data Center pointOfContact notPlanned Earth Science > Atmosphere > Clouds Earth Science > Biosphere > Ecological Dynamics > Fire Occurrence Earth Science > Human Dimensions > Environmental Impacts Earth Science > Spectral/Engineering > Infrared Wavelengths > Thermal Infrared Earth Science > Spectral/Engineering > Visible Wavelengths theme NASA/GCMD Earth Science Keywords DMSP Film Nighttime Lights OLS theme Uncontrolled Keywords ICSU-WDS > International Council for Science - World Data System project Global Change Master Directory (GCMD) Project Keywords 2020-01-09 publication 9.1 NASA Goddard Space Flight Center, Earth Science Data and Information System https://earthdata.nasa.gov/about/gcmd/global-change-master-directory-gcmd-keywords Global Change Master Directory (GCMD) Keywords The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

NCEI launched publicly on April 22, 2015. 2015-04-22T00:00:00 dataset Unknown Unknown The OLS film strips are scanned at or near 600 dpi (584 dpi for the Howtek scanner) on a high quality scanner with 8 bit quantitization (0-255). The film is illuminated from the opposite side of the scan head. The scanning is done on intact strips of film, up to 100 inches. Film longer than 100 inches may be cut and individually labeled prior to scanning. For expanded swath film the two strips of film will be separated, then labeled and scanned individually. TIFF files are converted to JPEG2000 (J2K) 8 bit images, file type jp2, with lossless compression. Once a box has cleared QC, the resulting jp2 images are written to a primary and backup LTO tape, into directories named based on box numbers (e.g. 007/400).
