=>En rentrant de nos vacances dans les Alpes, nous avons passé une journée près des gorges du Verdon, le grand Canyon européen (je sais, il y a une différence d’échelle avec l’Américain). Ceci dit, le paysage était superbe, comme vous pouvez le voir dans le panorama ci-dessous. Mais ne vous inquiétez pas, je ne […]

The departmental council of the Alpes de Haute-Provence has put online 6,500 km of hiking trails throughout its territory. These trails are visible on the site www.rando-alpes-haute-provence.fr which works with Geotrek software. To allow hikers to better prepare their outing, it might be useful to add the 20 m resolution snow maps produced by Theia […]

Sentinel-2 a deux bandes dans le moyen infrarouge, la bande 11 dite SWIR1 (centrée à 1,6 µm) et la bande 12 dite SWIR2 (centrée à 2,2 µm). Mais pourquoi deux bandes SWIR ? Le « Mission Requirements Document » (MRD) est un document central dans la définition d’une mission spatiale car il décrit les besoins auxquels la […]
Pre-processing (geometry, atmosphere, clouds)
After a very difficult period, and thanks to the installation of new improvements MUSCATE ground segment is back in shape, and margins have been found to add new sites. We have added two new zones where Sentinel-2 data are processed to Level 2A, which provide surface reflectance after atmospheric correction and a good quality cloud […]

When I present the potential of Sentinel-2 for snow science, I often tell that the spatial resolution of Sentinel-2 is sufficient to detect snow at the scale of the ski runs. Because a picture is worth a thousand words, here is the Sentinel-2 view of the only two ski resorts in southern Africa on July […]

You might have noticed the apparition of the first Venµs L2A products on Theia web site within the real time production, since last Friday. A first global processing will start this summer, to provide you with the data acquired from November until now. There will be probably further reprocessings to benefit from the fine tuning […]
