=>A first large scale data set of Sentinel-2 level 2A products was just issued by CNES. It contains all the data acquired by Sentinel-2 over France, from December 1st, 2015 until end of August. It was produced with MACCS on MUSCATE ground segment. The data can be downloaded from : In case all DNS are not […]
The giant ice avalanche that occurred in Tibet on 17 July 2016 and killed 9 people [1] urged scientists to scrutinize every available data to understand what caused such a glacier collapse. In doing so, they witnessed in near real time the ongoing collapse of a second glacier.
=> We are preparing the distribution of maps of the snow cover extent made from the Sentinel-2 data for Theia. If the method used to detect the snow is based on well-proven concepts, spatial and temporal resolution of the snow maps will however quite unprecedented. Until now, maps of the snow cover extent were usually produced […]
Nous avons deux gagnants ! We have two winners to the Sentinel-2 contest – Grand jeu-concours: Rutger & François! Bravo!
=> It is true that many of us can be moved by the Landsat L2A data produced by THEIA, but this time, the data were literally moved. The presently used downloading site http://theia.cnes.fr is being prepared to host Sentinel-2A data produced by the operational MUSCATE ground segment, and meanwhile, the prototype center goes on producing LANDSAT […]

=>The production of Level2A Sentinel-2A data by Theia is a little delayed, but we will still deliver, before the end of the month, the level 2A products acquired over France by Sentinel-2A so far. The production of the other selected sites, and the real time production will start a little later. It is not a piece […]
Wildfires were raging in California this summer. Let’s see if we can spot some of them in Sentinel-2A images with the new Sentinel-Playground by Sinergise. The combination of the SWIR and NIR bands of Sentinel-2 or Landsat enables to produce accurate maps of burnt areas. The SWIR band is sensitive to the water content in the […]
