CEOS Instrument: High Resolution Visible and Infra-red

Agencies: CNES [Primary]
Mission: SPOT-4
Type:High resolution optical imager
Description:2 HRVIR instruments provide 60 x 60 km images for a range of land and coastal applications
Spatial Resolution: 10 m (0.64 Ám) or 20 m
Swath Width: 117 km (i.e. 60 km + 60 km with 3 km overlap). Steerable up to ▒27 deg off-track
Wavebands: VIS: B1: 0.50 - 0.59 ?m, B2: 0.61 - 0.68 ?m, NIR: 0.79 - 0.89 ?m, SWIR: 1.58 - 1.75 ?m, Panchromatic:(B2) 0.61 - 0.68 ?m
Technology: High resolution optical imager
Description: Imaging Vis/IR radiometer whose characteristics are stressed towards spatial resolution (typically <30 m). Spectral coverage in bands of Vis and NIR (0.4-1.3 Ám). Number of channels can be small (extreme: one, i.e. panchromatic) or very large (hyperspectral) separated in-field (array detectors) or by a spectrometer, or a combination of both. Channel bandwidths from 0.5 Ám (PAN) to 5 nm (hyperspectral). Applicable only in LEO.
