  Description:
    Abstract:
      The Landsat-7 satellite is part of an ongoing mission to
      provide quality remote sensing data in support of research
      and applications activities. The U.S. entered into a
      partnership with NASA in the early 1970's to assume
      responsibility for the archive management and distribution
      of Landsat data products.  In July 1972, NASA launched the
      first in a series of satellites designed to provide
      repetitive global observations of the Earth's land masses.
      Part of NASA's Earth Resources Survey Program, the Earth
      Resources Technology Satellite (ERTS) Program, the ERTS
      satellites were later renamed Landsat to better represent
      the civil satellite program's prime emphasis on remote
      sensing of land resources.  Landsats 1, 2, and 3 carried
      the Multispectral Scanner (MSS) sensor and also included
      the experimental Return Beam Vidicon cameras.  The
      Landsat-4 satellite carried the MSS and Thematic Mapper
      (TM) sensors, as does the still currently orbiting
      Landsat-5 satellite.  The launch of Landsat-7 on April 15,
      1999 marks the addition of the latest satellite to the
      Landsat series. The Landsat-7 satellite carries the
      Enhanced Thematic Mapper Plus (ETM+) sensor.  A mechanical
      failure of the ETM+ Scan Line Corrector (SLC) occurred on
      May 31, 2003, with the result that all Landsat 7 scenes
      acquired from July 14, 2003 to present have been collected
      in 'SLC-off' mode.

    Purpose:
      The mission of the Landsat-7 satellite is to provide a
      vehicle for continuing the flow of global change
      information to users worldwide.  The Landsat-7 satellite
      fulfills its mission by providing repetitive, synoptic
      coverage of continental surfaces and by collecting data in
      spectral bands that include the visible, near-infrared,
      shortwave, and thermal infrared portions of the
      electromagnetic spectrum.

      Landsat-7 mission objectives include:  1) Maintaining
      Landsat data continuity by providing data that are
      consistent in terms of data acquisition, geometry, spatial
      resolution, calibration, coverage characteristics, and
      spectral characteristics with previous Landsat data. 2)
      Generating and periodically refreshing a global archive of
      substantially cloud-free, Sun-lit, land-mass imagery. 3)
      Continuing to make remote sensing satellite data available
      to domestic and international users and expanding the use
      of such data for global change research in both the
      Government and private commercial sectors. 4) Promoting
      interdisciplinary research via synergism with other EOS
      observations, specifically, orbiting in tandem with the
      EOS Terra satellite for near coincident observations.


    Supplemental_Information:
      The Landsat-7 system is another step in the development and
      application of remotely sensed satellite data for use in
      managing the Earth's land resources. As with earlier
      Landsat systems, the Landsat-7 platform, along with its
      enhanced thematic mapping sensor, provides for new
      capabilities in remote sensing of the Earth's land
      surface.

    The Landsat Program, as defined by Congress in 1992 and amended
    by Presidential Decision Directive/NSTC-3 in May 1994, is
    managed cooperatively by the National Aeronautics and Space
    Administration (NASA) and the USGS.  Responsibility for
    construction of the spacecraft and instrument lies with NASA.
    The Landsat Program is part of NASA's Earth Observing System
    global change initiative administered by NASA's Earth Science
    Enterprise. Data processing, archiving, and distribution are
    performed by the USGS.  The primary ground station, the data
    handling facility and archive are located at the USGS Center
    for Earth Resources Observation and Science (EROS) in Sioux
    Falls, SD.  NASA managed flight operations from the control
    center at the Goddard Space Flight Center until October 1,
    2000, at which time responsibility for flight operations
    transferred to the USGS.  The ground system is able to
    distribute raw ETM+ data within 24 hours of its reception at
    the EROS.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report:
      The identification of features is provided by the distinct
      electromagnetic energy it emits,  reflects, or otherwise
      transmits.  This is called the spectral signature.  Other
      signatures such as tone (lightness or darkness), texture
      (surface roughness or smoothness), pattern, shadow, shape,
      and size are as important.  Thus, through the use of the
      enhanced thematic mapper sensor, such elements as water
      features, soils, and vegetation can be identified and
      distinguished from each other.

    The Landsat-7 satellite is designed to fly a 705-kilometer,
    Sun-synchronous, Earth mapping orbit with a 16-day repeat
    cycle. The orbital pattern equates to a 233-orbit cycle with a
    swath sidelap that varies from approximately 7 percent at the
