Sur une image Pléiades acquise le 15 janvier, Etienne a remarqué une fracture qui traverse une bonne partie de la langue du glacier de l’Astrolabe auprès de la base Dumont-d’Urville en Antarctique. On peut reconstituer l’ouverture de cette crevasse à partir d’une série d’images Sentinel-1 (une année complète de janvier 2020 à janvier 2021) D’après […]
In the previous post, Olivier advocated for the open data policy in remote sensing. Although Oliver is facing some actual resistance because the Sentinel-HR mission would step on the toes of industrial champions, my feeling is that there is now a large consensus on this issue. The economic and social benefit of the open data […]

Snow and ice products are now available at high resolution (20×20 m) for all Europe in near-real time. However, Magellium is also processing the Sentinel-2 archive since September 2016. About 70% of Sentinel-2 observations have already been processed and 50 % are already published. This huge computation is being done on the CNES HPC […]

A sunny Sunday just after an exceptional late-September snowfall… That’s already a stroke of luck. But the passage of Sentinel-2 on the same day makes this weekend even more special! The snow cover map was immediately processed and distributed by the new Copernicus Snow & Ice monitoring service powered by Cesbio’s algorithms! You can explore […]
En partant de Boutx (780 m) on peut monter au Pic Saillant (1756 m) (voir le topo) et admirer un magnifique panorama hydrologique sur le haut bassin de la Garonne et de son affluent la Pique. Par temps clair, on peut deviner les sommets du Luchonnais encore enneigés au mois de juillet qui marquent la […]
