  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.

  Data_Set_Credit:  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.
  Logical_Consistency_Report:  N/A
  Completeness_Report:  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  Equator to nearly 84 percent at 81 degrees north or south latitude.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report:  583 Meters. Represents the horizontal
distance between the perpendiculars through the LPS calculated "true" WRS
Scene Center and the nominal (known) WRS scene center on the ground (positive = West
shift, negative = East).
