Following SPOT satellite family, PLEIADES-HR is a high resolution optical earth observation system developed by CNES and consisting in two satellites with a first launch by the end of 2009. Pleiades-HR will deliver both 70 cm Panchromatic images and 2.8 m multispectral (blue-green-red-near infrared) images with a 21km swath. As for SPOT images, Pleiades-HR ground segment includes a systematic and...
A new cloud detection technique has been developed and applied to both geostationary and polar orbiting satellite imagery having channels in the thermal infrared and short wave infrared spectral regions. The bispectral composite threshold (BCT) technique uses only the 11 mum and 3.9 mum channels, and composite imagery generated from these channels, in a four-step cloud detection procedure to produce...
