Definition of Products

Level 0 Raw (TM Products)
Raw uncorrected data with no radiometric or geometric correction applied. Scan lines reversed and nominally aligned.

Level 0 Reformatted (ETM Products)
Raw uncorrected data with no radiometric or geometric correction applied. Reformatting includes shifting pixels by integer amounts to account for 1) the alternating forward-reverse scanning pattern of the sensor, 2) the odd-even detector arrangement within each band, and 3) the detector offsets inherent to the focal plane array engineering design. The pixels are NOT aligned per scan line.

Level 1 Radiometrically corrected (TM Products)
Radiometric calibration applied. Scan lines reversed and nominally aligned, but no geometric correction applied.

Systematically corrected
Radiometrically and geometrically corrected using the satellite model and platform/ephemeris information.  Rotated and aligned to the user defined map projection.   

Map Registered/Precision corrected
Radiometrically and geometrically corrected using the satellite model and platform/ephemeris information.  Rotated and aligned to the user defined map projection using ground control points to improve the satellite model.

Terrain corrected
Radiometrically and geometrically corrected using the satellite model and platform/ephemeris  information.  Rotated and aligned to the user defined map projection using ground control points and digital terrain model to improve the satellite model and remove the geodetic inaccuracy caused by the parallax error that occurs because of local terrain elevation.

• W84 = WGS84
• N83 = NAD83
• N27 = NAD27

• SOMB - Space Oblique Mercator
  • Used for mapping imagery from Landsat and other satellites with nearly circular orbits. The following characteristics are applicable to the Space Oblique Mercator projection.
  • Modified cylindrical.
  • Basically conformal.
  • Parallels are curved lines.
  • Meridians are curved lines except at each polar approach.
  • Scale is true along ground track of satellite.
• UTM - Universal Transverse Mercator
  • An ellipsoidal Transverse Mercator projection to which specific parameters have been applied. The earth is divided into 60 zones which are 6 degrees wide.

  Ground Control Point software automatically adds a false northing of 10,000,000 meters if the first coordinate is south of the equator. Problems may occur when working around the equator.

  When working in the Southern Hemisphere, enter a negative zone code.

• 25 = 25 meter TM or ETM+ (ETM+ only Thermal Band = 50 meters/Panchromatic Band = 12.5 meters)
• 28.5 = 28.5 meters TM or ETM+ (ETM+ only Thermal Band = 57 meters/Panchromatic Band = 14.25 meters)
• 30 = 30 meters TM or ETM+ (ETM+ only Thermal Band = 60 meters/Panchromatic Band = 15 meters)
• 57 = 57 meters MSS
• 60 = 60 meters MSS

• CC ( = cubic convolution)
  Computes the new output values by taking a distance-weighted average of the nearest 16 input pixels This generally produces a smoother image, with larger areas of similar values.
• NN ( = nearest neighbor)
  Computes the new output value by using only the value of the nearest input pixel. NN will be much closer to the true values of the original pixels, and will produce a much choppier image with sharper boundaries between the pixels.

• F = Full
• N = None
• C = Coarse

• MAP = The image data is geographically rotated to a North Up orientation (map).
• SAT = Nominal system (path) orientation applied to the image data.

• Y = DEM is available with scene that is ordered (only if scene coverage is within the United States of America).
• N = DEM not available with scene ordered.

• NDF - NLAPS Data Format =
  • Geometrically and radiometrically corrected products are provided in the National Landsat Archive Production System (NLAPS) data format. The NLAPS system is designed to support a variety of sensors. Currently, USGS Earth Resources Observation and Science Center (EROS) uses the NLAPS system to process data and produce products from data collected by the Landsat multispectral scanner (MSS) sensor and the thematic mapper (TM) sensor.
• GEO - GeoTiff Format =
  • GEOTIFF defines a set of public domain (TIFF) tags that describe all cartographic and geodetic information associated with geographic TIFF imagery. GeoTIFF is a means for tying a raster image to a known model space or map projection and for describing those projections. A metadata format provides geographic information to associate with the image data, but the TIFF file structure allows both the metadata and the image data to be encoded into the same file. The GeoTIFF file is grayscale, scanline, uncompressed, and 8-bit unsigned integers.
• FSTL7 - Fast L7A =
  • Geometrically and radiometrically corrected ETM+ products are provided in the FastL7A format which has each band self contained in its own file (i.e. external element style). A header file containing three records accompanies the image data. The three records in order of appearance are labeled administrative, radiometric, and geometric respectively. Sensor specific information is placed in the administrative record, gains and biases can be found in the radiometric record while projection information and image coordinates are stored in the geometric record.
• HDF - Hierarchical Data Format =
  • The HDF software is developed and supported by NCSA.
• LTWG - Landsat Technical Working Group
