Visualizing shipping lanes from Sentinel-1
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.

=>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 […]
Sentinel-2 Level3A time series (July, August, September 2018)
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 […]
Snow cover duration from 01 Sep 2017 to 31 Aug 2018 in the Alps and Pyrenees
=> 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 […]
Durée d’enneigement dans les Alpes et les Pyrénées du 01/09/2017 au 31/08/2018
=> 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) : […]

A seamless and cloudless Sentinel-2 image of France in July 2018
=> 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 […]
