=> The MUSCATE processing centre at CNES, which belongs to French THEIA land data centre, produces and distributes all the Landsat 8 data acquired above France at Level 2A. Level 2A products contain surface reflectances after atmospheric correction, and a very good cloud mask. LANDSAT 8 first routine data had been acquired on April 13th […]
=> The validation of MUSCATE, CNES ground segment to process Sentinel-2 data, and MACCS (our L2A software) is going on, in order to start processing Sentinel-2A data at level 2A soon (in a few weeks…). A previous post compared MACCS cloud masks with those of Sen2cor. For this one, time series have been generated for […]
=> A couple of days before the living planet symposium, ESA issued a new version of Sen2cor (V2.2.1), the Sentinel-2 atmospheric correction toolbox. I had made a first comparison of MACCS and Sen2cor results using V2.0.6, regarding the cloud masks mainly, in which I concluded the scene classification was really bad, but probably due to […]
I did not have the chance to attend the latest ESA’s Living Planet Symposium so I was curious to read Olivier’s report. The picture in his post shows a crowded room… but what stroke me most is that it looks like 90% of the people in the room are middle-age men. There is no public […]
If I haven’t posted for more than a week, it is because I have been participating to the Living Planet Symposium 2016 in Prague. With the preparation, travel, and participation to this crazy symposium. I say crazy because it is packed with about 3000 people, of which I know only about 300. When you want […]
=> Optical remote sensing is great to map the snow cover extent in mountain regions as long as there is no cloud above the land surface. Radar remote sensing of the snow cover is not operational yet mainly because the backscatter from the snow surface is strongly dependent on the snowpack liquid water content. On […]
=>The SPOT5 (Take5) project just released a new version of all SPOT5 (Take5) L2A data to account for several small issues encountered during the first processing :
=> Don’t worry, everything is fine for SPOT5 (Take5) ! While SPOT5 is peacefully getting some well deserved rest, THEIA just reprocessed the Take5 data to solve a little list of issues detected after the first processsing. The data should be released very soon. The most significant change involves the cloud shadows mask computed by […]
J’ai adapté mon outil de téléchargement de données Sentinel-2, pour que l’on puisse ne télécharger qu’une tuile à la fois, au lieu de télécharger toutes les tuiles du produit. Ce n’était pas simple, parce qu’il faut récupérer les données fichier par fichier et répertoire par répertoire. mais ça a l’air de fonctionner. Voici un exemple […]
