The LISS-IV camera is a high resolution multi-spectral camera
operating in three spectral bands (B2, B3, B4). LISS-IV can be
operated in either of the two modes. In the multi-spectral mode (Mx),
a swath of 23 Km (selectable out of 70 Km total swath) is covered in
three bands, while in mono mode (Mono), the full swath of 70 Km can be
covered in any one single band, which is selectable by ground command
(nominal is B3 - Red band). The LISS-IV camera can be tilted up to
+-26 degrees Celsius in the across track direction thereby providing a
revisit period of 5 days.
The Data products are categorized as Standard and have a system level
accuracy.
LISS-IV Standard Products comprise Path/Row Based products, Shift
Along Track product, Georeferenced products and Basic Stereo
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. Georeferenced products
are true north oriented products. These products are supplied on
digital media only. Basic Stereo products comprise pairs of two images
of the same area, acquired on different dates and from different
angles. One of the parameters from which the quality of a stereo pair
can be judged is the base/height (B/H) ratio. B/H ratio is the ratio
of distance between two satellite passes and satellite
altitude. Stereo products are available from LISS-IV Mono mode
only. The inputs required, in addition to path/row details is B/H
ratio. Two scenes selected on two different dates, satisfying the
user's B/H ratio are supplied as a stereo pair. The data is only
radiometrically corrected and are supplied on digital media.
Standard Based and Geo Referenced products cover an area of 23 x 23 km
(3Mx bands) and 70 x 70 km (Mono mode). Basic Stereo products are
Radiometrically corrected and cover an area of 70 x 70 km (Mono mode).
