SHARP is the ESA-Earthnet format for AVHRR and TOVS data. It stands for
Standard-family HRPT Archive Request Product. It adopts the
internationally-recognised Standard-Family Tape Format as defined by the
Landsat Technical Working Group (LTWG).
AVHRR scenes (4 minutes of data), which can cover an area 3000 x 6000km, are
provided in SHARP format. TOVS data ... (the low-data-rate atmospheric sounding
package on the NOAA satellite) is also provided, for the entire pass, with each
AVHRR scene. Auxiliary information such as ground reference points, orbit and
attitude data, calibration coefficients and geographical information
(coastline, state boundaries and/or latitude longitude grid flags) are also
provided with the image data.
SHARP-1 is the implementation of the superstructure concept of the
High-Resolution Picture Transmission (HRPT). It contains the raw digital
data with the supplementary information like latitude/longitude Grid,
coastlines, state boundaries.
Image Navigation (location) is carried out during Level 1 data generation,
using the orbital model for the satellite location, and is tested by an
operator who carries out further correction if necessary.
