Description
The SPOT series of satellites carry two nominally identical High
Resolution Visible (HRV) imagers which can be operated
independently or in various coupled modes. They have four
straight and continuous virtual sensing lines, with 6000 basic
sensing elements per line. These instruments are, however, not
limited to nadir viewing. Each HRV contains a pointable mirror
apparatus which allows the imaging direction to be varied at
user-selected angles. Each HRV imager has two sensing
modes. They are known as the Multi-Linear Array (MLA) and the
Panchromatic Linear Array (PLA) sensors. The MLA sensor
captures data in three spectral bands: 500 - 590 nm, nominal
ground resolution of 20 metres at nadir. The PLA sensor
captures data in the spectral range 510 - 730 nm at a 10 metre
nominal ground resolution at nadir. Data are archived at a rate
of approximately 100,000 (60 km x 60 km) scenes per year. Each
data set contains visible and near-infrared radiance data. The
data are stored on h igh density tapes and are available in
Digital and film format at a variety of processing levels from
raw levels to fully-processed products registered to the
Canadian National Topographic Map series. The data are offered
in LGSOWG, EOSAT fast format and ARCinfo.
