What are the spatial, spectral, radiometric, and temporal resolutions of SPOT 5?
SPOT 1-5 Panchromatic and Multispectral Mode Improved spatial resolution compared with Landsat Off-nadir viewing capabilities are extremely helpful Can point the sensor “off-nadir” to obtain stereoscopic imagery http://www.spot.com/html/SICORP/_401_.php Systeme por l’Observation de la Terre (SPOT) Systeme Por l’Observation de la Terre (SPOT)
