=> The L2 products from the Maja chain are regularly evaluated for their quality, whether in terms of cloud detection, optical thickness estimation or surface reflectance estimation. While the validation of the cloud masks is essentially based on the tedious creation of sets of controls (manual or semi-automatic), the estimation of the optical properties of […]
=> Les produits L2 issus de la chaine Maja font régulièrement l’objet d’une évaluation de leur qualité, que ce soit de la détection des nuages, de l’estimation des épaisseurs optiques ou de l’estimation de la réflectance de surface. Si la validation des masques de nuages repose essentiellement sur la fastidieuse création de jeux de contrôles […]
Yes, so far MUSCATE is winning against COVID ! MUSCATE is THEIA land data production center in CNES. Although everyone in the production and development team is working from home, in good health so far, the production is still on, as you may see on the counters. We even passed the 10 000 products milestone […]
CESBIO is the home of a highly motivated bunch of open source software advocates ! Let’s have a look at some the main softwares to which CESBIO members contributed, and which are available on various git platforms : WASP IOTA2 LIS S1-Tiling But one of our softwares was only distributed freely as a binary package, […]
Venµs is a research satellite, and a rather agile one (at least for a microsatellite). It enables us to make experiments useful for users like us who like to study physics of optical measurements (which is an allowed perversion, as fas as I know). We have started last year to acquire multi-angular observation, under 3 […]
1/ New 5m Level 2 products The Venus L2 production has been moved to a different processing center. From January 2020, the VENµS L2 production is only performed by the MUSCATE processing center, instead of the VIP (VENµS Image Processing) center, with MAJA processor also used for Sentinel-2. The aim is to improve the integration […]
=> I take the advantage of this post to wish you all nice holidays, a merry christmas and a happy new year ! It will have taken us almost a year to process the 300 Sentinel-2 tiles in Theia’s area in Sahel, from the beginning of January 2017. This processing ends next week, and […]
=> Je profite de cet article pour vous souhaiter à tous de bonnes vacances, un joyeux Noel, et une excellente nouvelle année 2020 ! Il nous aura fallu près d’un an pour traiter les 300 tuiles de la zone Sahel de Theia, à partir de début Janvier 2017. Ce traitement s’achève ces jours-ci, il […]
In September 2019, the German Aerospace agency, DLR, started delivering Level-2A products (surface reflectances with a good cloud mask), using the MAJA L2A processor, to which DLR contributed with CNES and CESBIO. The system received a major upgrade recently: it now includes L3A data (seamless monthly syntheses generated with our WASP processor), and both L2A […]
