Since the 2nd of February, a new parametrization was put in production in order to improve two points of the cloud masks. There is a page which summarizes the variations of Theia product versions.

Connaissiez-vous ce dicton coréen « On n’est jamais trop prudent » ? Voici une série d’images Sentinel-2 près du site olympique de Pyeongchang. On voit de la neige artificielle apparaître dès le mois de novembre ! Les images suivantes montrent qu’au cours du mois de janvier de la neige naturelle a finalement recouvert le site…
En voyant ce titre dans la Dépêche, j’ai imaginé que les célèbres géoglyphes de Nazca avaient été complétement labourés. Peut-on utiliser Sentinel-2 pour constater l’ampleur des dégâts ? La dernière image du site a justement été acquise le lendemain du drame. Dans cette région aride du Pérou, les nuages sont rares, si bien qu’on peut […]

Great news, we can announce that the operational production of the Theia snow collection has started well. It means that maps of the snow cover area are now constantly added to the Theia portal. These maps are automatically generated from Sentinel-2 observations and have a spatial resolution of 20 m. The Snow collection will progressively […]

It was one of the big buzz pages of the blog in 2016. The first images were published here, then spread out in many scientific websites and the social networks. It seems […]
Sentinel-2 a acquis cette belle image de la campagne autour de Notre-Dame-des-Landes le 17 janvier 2018, le jour même où le Premier ministre annonçait que le projet d’aéroport du Grand Ouest était abandonné. Pour fêter l’occasion le ciel breton s’était éclairci !
The Sentinel-2 mission status document, edited by ESA, is a very interesting reading. On its last edition of 2017, ESA announced very discretely that the spectral bands of Sentinel-2 had been revised, following a review of the pre-flight measurements. Very few details are provided on the nature of the error contained in the previous version, […]
