THEIA/MUSCATE nears real time for Sentinel-2 L2A
THEIA MUSCATE production of Sentinel-2 L2A products nears real time, and L2A products acquired until March 2017 over France and Reunion Island have started to appear on our distribution server : The production will progressively be extended over the whole France and over the other sites (Spain, Morocco, Belgium Tunisia, Senegal, Burkina, Mali…) and then […]
Quantitative comparison of cloud masks from MACCS/MAJA, Sen2Cor and GEOSYS (hand made)
=> As already explained in a previous post, we obtained some Sentinel-2 hand made cloud masks from GEOSYS company. We used those to validate the cloud masks from MACCS/MAJA. But we wanted to use them further to make a quantitative comparison with Sen2Cor cloud masks.But this comparison required solving a little issue : GEOSYS cloud masks […]
5000 produits L2A Sentinel-2A ajoutés sur le serveur Theia
=>🙂 🙂 🙂 Après avoir répété pendant des mois, « désolé, notre production a pris du retard pour telle ou telle raison« , dans des articles de blog, au téléphone, en réunion, par email, sur twitter, vous ne pouvez pas imaginer le plaisir que j’éprouve à annoncer que le CNES vient de mettre en ligne de grandes […]
MACCS qualified for Atmospheric Correction Euro and World Cup
Don’t worry, I have not been converted to a football fan, it is still giving me allergies ! But after a post about sex ratio, we are still trying to increase the amount of connexions to this blog. However, the title of this post is partly true, since, simultaneously, we are engaged to two competitions to […]
New game : spot the artefacts in S2A L2A mosaics
=> 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 […]
Nouveau jeu, cherchez l’artefact dans les mosaiques de Niveau 2A de Sentinel-2
=>La validation de MUSCATE et MACCS se poursuit, dans le but de démarrer prochainement le traitement des données de niveau 2A (dans quelques semaines). Un post précédent comparait les masques de nuages issus de MACCS avec ceux de Sen2cor, la chaîne de l’ESA. Des séries temporelles ont récemment été traitées sur 4 sites, et sur […]
First test of Sen2cor 2.2.1 (and comparison with MACCS)
=> 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 […]
First comparison of Sentinel-2 cloud masks delivered by MACCS and SEN2COR
=> A new version o Sen2cor has been published recently, and this comparison was re-iterated with Sen2cor 2.2.1. The corresponding post is published here. While CNES is getting ready to produce and distribute Sentinel-2A products obtained with our MACCS processor, I have been asked by impatient users what I thought of SEN2COR Sentinel-2 cloud masks. […]
