Count Component Title Abstract
1 Defense Meteorological Satellite Program (DMSP) Film The United States Air Force Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) is a polar orbiting meteorological sensor with two spectral bands (visible and thermal infrared) capable of acquiring global coverage on a daily basis at .27 km spatial resolution. 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.

      1 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).

      1 2002-08-31T00:00:00 The OLS film strips should be scanned at or near 600 dpi on a high quality scanner with 8 bit quantitization (0-255). The film should be illuminated from the opposite side of the scan head. The scanning will be done on strips of film that fit on the scanner bed. Film longer than the scanner bed 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 MrSid file type sid, with lossy compression. Once a box has cleared QC, the resulting sid images are written to a primary and backup LTO tape, into directories named based on box numbers (e.g. 007/306). 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 CD, into directories named based on box numbers (e.g. 007/400).

      1 Defense Meteorological Satellite Program The DMSP is a Department of Defense (DoD) program run by the Air Force Space and Missile Systems Center (SMC). Each DMSP satellite has a 101 minute, sun-synchronous near-polar orbit at an altitude of 830km above the surface of the earth. Currently, data from 4 satellites (3 day/night, 1 dawn/dusk) are added to the archive each day.
