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 […]
About one year ago, we had submitted a call for ideas for the use of VENµS imager after the end of its nominal phase. CNES also organised a brain storming meeting, which came up with a few ideas, and then our proposals were discussed with our israeli partners. Here is what was agreed between CNES […]
S. P. Hicks (@seismo_steve) wrote for Nature Geoscience a nice piece « Geoscience analysis on Twitter » where he shares his experience on using Twitter for the real time analysis of geohazards. Actively using Twitter for science may be perceived by some as a significant time-sink — the demands on individual researchers and their institutions at times […]
=> In this period of festivities, feasts, gifts and good resolutions, the contrast is strong with the gloomy balance sheet of the year 2019 for our blog, which for the first time shows a pathetic drop in traffic: -9%. Faced with such a worsening situation, the editorial board must react and take remedial action, and […]
=> This is the eighth time this blog wishes you a Happy New Year! We send you and your loved ones our best wishes for personal, family and professional happiness for the year 2020. On our program for this new year: And of course :
Sentinel-2 image time series are widely used to map land cover, see for instance here or here. However, they can be used to extract other relevant information about the observed landscapes. In a recently published article (https://doi.org/10.1016/j.rse.2019.111536), we have used fifteen months of Sentinel optical and radar data to predict taxonomic and functional diversity at […]
=> 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 […]
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 […]
