Recently I generated one year of snow maps from Sentinel-2 in the Canadian Rockies for a talented colleague who is working on the numerical simulation of the snow cover at high-resolution with an exciting new hydrological model. The area is not covered by Theia, hence I used Start_Maja to generate the L2A products and then […]
WASP (Weighted Average Synthesis Processor) is the tool we use to compute the nice (mostly) cloud free syntheses of Sentinel-2 surface reflectances, as shown in the images below. A full resolution viewer is also available in this post, or you may also download the products you can download from Theia. As promised (but it took […]
I found in Twitter [1,2,3] that a simple way to visualize the sea lanes is to compute the maximum of each pixel across a time series of Sentinel-1 images.
=> For the past few months, Copernicus has been distributing Level 3A products for the Sentinel-2 mission as part of the S2GM (Sentinel-2 Global Mosaics) . This ambitious project aims to provide monthly, quarterly or annual Level 3A products worldwide. The user defines his zone and period of interest and orders the product. The web site […]
=>Copernicus diffuse depuis quelques mois des produits de niveau 3A pour la mission Sentinel-2 dans le cadre du projet S2GM (Sentinel-2 Global Mosaics). Ce projet très ambitieux a pour but de fournir, à l’échelle mondiale, des synthèses mensuelles, trimestrielles ou annuelles. L’utilisateur définit sa zone et sa période d’intérêt et commande le produit. Le site est […]
If you are not afraid to spend too much time while you have urgent things to do, you may have a look to the mosaic of Sentinel-2 monthly syntheses for September over France. You may access to each monthly synthesis using the following links : Or you may also use the viewer below to compare […]
=> 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) : […]
=> (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 […]
