=> We are thinking to distribute a new product that would provide the snow cover duration in the Alps and the Pyrenees over a hydrological year (snow persistence map). Here is a preview of a « beta » version that is only 100 m resolution for now. A few words on the method (see also here): this […]
=> Nous sommes en train de penser à un nouveau produit qui donnerait la durée d’enneigement dans les Alpes et les Pyrénées au cours de la dernière année hydrologique. Voici ci-dessous un aperçu d’une version « beta » (artisanale) qui n’est qu’à 100 m de résolution pour l’instant. Quelques mots sur la méthode (voir aussi ici) : […]
Le photographe (et directeur technique) a du sortir son objectif grand angle pour photographier la famille Theia, lors du séminaire bisannuel qui avait lieu les 17 et 18 octobre 2018 à Montpellier. Ce fut un véritable stage de motivation, et un grand plaisir de recevoir tous ces retours positifs sur les travaux des chercheurs Français […]
=> (Mise à jour le 4 octobre 2018) Cet été, alors que la plupart d’entre nous prenions des coups de soleil sur la plage, nous faisions dévorer par des moustiques, attrapions des courbatures en rando, ou faisions de longues siestes pour nous remettre de nuits fatigantes, les équipes de production et de distribution de MUSCATE […]
=> Updated on October 4th This summer, while most of us were getting sunburnt near the coast, or getting sore legs after hiking in mountains, or having long naps after hectic nights, the lucky MUSCATE teams stayed at work, with a good and efficient air conditioning, convenient armchairs, fast computers and accessed to the best canteen […]
Update : we added a script to submit and download MAJA jobs on PEPS Getting a Sentinel-2 L2A product (with atmospheric correction and cloud detection) anywhere has never been so easy. Until now, you had two options to access to Sentinel-2 L2A products obtained from the MAJA processor : Starting from today, there is another […]
On Sep 28 a 7.5 magnitude earthquake struck the city of Palu, in Sulawesi Indonesia. The quake was followed by a tsunami. The animation below shows two Sentinel-2 images before and after the earthquake in Palu. If you look closely you can see the horizontal displacement due to the fault movement through the city. It […]
An earthquake with magnitude 6.7 occurred on 06 Sep 2018 in Hokkaido, Japan, killing at least 17 people and leaving nearly 3 million households in Hokkaido without electricity. The quake came two days after typhoon Jebi, « the strongest storm of 25 years« . Below is an image comparison near Atsuma dam lake in the south of Hokkaido, […]
=> UPDATE: resolution improved to 20m ! I had to tinker a couple of days with Theia’s Sentinel-2 monthly syntheses, in order to produce the mosaic below. For that, I used: This mosaic best resolution is 20m. It is already requiring 8 GB. We could have provided it at 10m resolution, but it would have […]
