LISS-III Data Products

The Linear Imaging Self Scanning Sensor (LISS-III) is a multi-spectral
camera operating in four spectral bands, three in the visible and near
infrared and one in the SWIR region, as in the case of IRS-1C/1D. The
new feature in LISS-III camera is the SWIR band (1.55 to 1.7 microns),
which provides data with a spatial resolution of 23.5 m unlike in
IRS-1C/1D (where the spatial resolution is 70.5 m).

The Data products are categorized as Standard and have a system level
accuracy.

LISS-III Standard Products comprise Path/Row Based products, Shift
Along Track product, Quadrant products and Georeferenced
products. Path/Row Based products are generated based on the
referencing scheme of each sensor. Shift Along Track applies to those
products covering a user's area of interest which falls in between two
successive scenes of the same path, then the data can be supplied by
sliding the scene in the along track direction. LISS-III full scene is
divided into four nominal and eight derived quadrants. LISS-III
photographic quadrant products are generated on 1:125,000
scale. Georeferenced products are true north oriented products. These
products are supplied on digital media only.

Standard Path/Row Based products cover an area of 141 x 141 km and are
characterised by 3 Bands. Path/Row Based products comprise Raw,
Radiometrically corrected and Geo referenced levels of
corrections. Quadrant products cover an area of 70 x 70 km and are
characterised by 3 or 4 Bands (Geo Referenced). Quadrant products
comprise Standard and Geo referenced levels of corrections.
