=> It is with a deep nostalgia that I learned that Formosat-2 has just been decommissionned, after some of its components broke down after 12 years of acquisitions (nominal life extended by 8 years !). When the satellite was launched, we were searching for data sets that would allow us simulate the features of VENµS satellite (which […]
=> Deux ou trois jours avant le symposium Living Planet, l’ESA a mis en ligne la nouvelle version de Sen2cor (V2.2.1), le logiciel de correction atmosphérique de Sentinel-2. J’avais déjà publié une comparaison basée sur la version V2.0.6, dans laquelle je concluais que la détection des nuages et des ombres était très mauvaise, mais que c’était […]
=> La télédétection satellite optique est un outil formidable pour suivre l’étendue du manteau neigeux en montagne… sauf quand il y a des nuages ! La télédétection radar du manteau neigeux (indifférente aux nuages) n’est pas encore opérationnelle en zone de montagne, notamment en raison du fait que le signal rétro-diffusé par le manteau neigeux […]
=> MUSCATE is a name you may have already read on this blog. It is the processing ground segment CNES set up for THEIA land data center. We used to process SPOT (Take5), Landsat 8 or SpotWorldHeritage data with a prototype ground segment. But to produce the Sentinel-2 level 2A data we had to scale up […]
Dans le poisson (même d’Avril), tout n’est pas bon. Rétablissons les faits : Si vous tenez malgré tout à lire mes élucubrations poissonnières :
=> The first thing we do in the morning at CESBIO is a break : the coffee break. This is the perfect time to gather field information on the state of the snow cover in the Pyrenees. This year everyone agrees that snow is rare … Can we check this using remote sensing?
=> The SPOT5 (Take5) experiment ended today around 12 (UTC). Sintce the 8th of avril, about 5000 images were acquired on 150 sites every 5 days. Finally, everithing work without too many incidents, even if the first weeks were full of surprises. This work implied a lot of people to obtain the project funding and decision, to […]
