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: 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. Generating and periodically refreshing a global archive of substantially cloud-free, Sun-lit, land-mass imagery. 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. Promoting interdisciplinary research via synergism with other EOS observations, in particular, 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.

Landsat-7 data are collected from a nominal altitude of 705 kilometers in a near-polar, near-circular, Sun-synchronous orbit at an inclination of 98.2 degrees, imaging the same 183-km swath of the Earth's surface every 16 days. Some of the browse images you encounter may appear black or empty. These are engineering data known as FAC=Full Aperture Calibrator. FAC is a white painted panel that is deployed in front of the ETM+ aperture and diffusely reflects solar radiation into the full aperture of the instrument. FAC scenes will typically be gathered on a daily basis and constitute roughly 10 scenes for each FAC collected. So, about 10 of the ~250 scenes per day that Landsat will be delivering to EDC will be FAC scenes. Eventually, this engineering data will be gleaned out of the database.

Attribute_Accuracy_Report:
A panchromatic band 8 was added, with a resolution of 15 meters. Band 6 now has high gain and low gain bands. There are 3 on-board solar calibrators to provide an absolute accuracy of 5%.

Landsat-7 data are collected from a nominal altitude of 705 kilometers in a near-polar, near-circular, Sun-synchronous orbit at an inclination of 98.2 degrees, imaging the same 183-km swath of the Earth's surface every 16 days.
Completeness_Report:
The Landsat-7 satellite is designed to fly a 705-kilometer, Sun-synchronous, Earth mapping orbit with a 16-day repeat cycle. Its payload is a single nadir-pointing instrument, the ETM+ sensor. Communications are provided through the satellite's S-band and X-band. The S-band is used for command and housekeeping telemetry operations while the X-Band is used for instrument data downlink. A 378-gigabit solid state recorder can hold 42 minutes of instrument data and 29 hours of housekeeping telemetry, concurrently. Power is provided by a single Sun-tracking solar array and two 50-amp-hour, nickel-hydrogen batteries. Attitude control is provided through four reaction wheels (pitch, yaw, roll, and skew), three 2-channel gyros with celestial drift updating, a static Earth sensor, a 1750A processor, and torque rods and magnetometers for momentum unloading. Orbit control and backup momentum unloading is provided through a blow-down monopropellant hydrazine system with a single tank containing 270 pounds of hydrazine, associated plumbing, and twelve 1-pound-thrust jets. 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. The Landsat-7 satellite is to share its orbit configuration with NASA's Earth Observing System (EOS) Terra satellite (launch pending). Plans are for the two satellites to be placed in identical orbits, ideally 15 minutes apart from each other, with the EOS Terra satellite in a follow-on orbit to the Landsat-7 satellite. The end result is repetitive data coverage, while such variables as plant physiology are under nearly identical conditions. The Landsat scenes are mapped to a global notation system called the Worldwide Reference System (WRS), annotating the nominal scene center of Landsat imagery using Path and Row designators.

The Landsat ETM+ sensor is a nadir-viewing, eight-band multispectral scanning radiometer that detects spectrally filtered radiation from several portions of the electromagnetic spectrum while orbiting the Earth from an altitude of 705 kilometers. Nominal ground sample distances or pixel sizes include 30 meters each for the six visible, near-infrared, and shortwave infrared bands, 60 meters for the thermal infrared band, and 15 meters for the panchromatic band. The ETM+ sensor is designed to produce approximately 3.8 gigabits of data for each Landsat scene. The Landsat ETM+ sensor operates from a 3-axis, stabilized satellite platform. With the platform traveling in a Energy reflected from the Earth's surface passes through several ETM+ subsystems before being collected by the solid-state detectors at the focal plane.

Spatial_Data_Organization_Information:
Indirect_Spatial_Reference:
Spectral bandwidths for the ETM+ sensor are determined through the combined response of all the system's optical path mirrors (e.g., primary, secondary, scan line corrector), spectral filters, and individual detectors. The spectral filters, located immediately in front of each detector array, predominately establish the optical bandpass for each spectral band. The filter housing for the prime focal plane contains filters for bands 1 through 4 and for band 8 (the panchromatic band). The filter housing for the cold focal plane assembly contains filters for bands 5 through 7.

Ordering_Instructions:
Data set searching and ordering capabilities of Level-0 Reformatted (L0R), Level-1 Radiometrically Corrected (L1R), and Level-1 Geometrically Corrected (L1G) are available through EarthExplorer system at EarthExplorer system at:

<http://earthexplorer.usgs.gov> . The L0R data are reformatted, raw data acquired by the satellite as it views the Earth. The data are not radiometrically corrected, the pixels are not resampled or geometrically registered to an Earth location.

The L1R product is a radiometrically corrected image. Radiometric correction is performed using either gains in the Calibration Parameter File or gains computed on the fly from the Internal Calibrator. The choice is available to a user when the product is ordered. Radiometric corrections are not reversible. The L1R product geometry is identical to the input L0R data. These L1R data are available to approved researchers only.

The L1G product is a radiometrically and systematically corrected L0R image. The correction algorithms model the spacecraft and sensor, using data generated by onboard computers during imaging events. The radiometrically corrected pixels are resampled for geometric correction and registration to an Earth location with a geodetic accuracy of 5 to 25 times the sensor's ground instantaneous field of view.
