=> The aim of « Bagré 2015 » campaign was to closely monitor the spatio-temporal evolution of turbidity and Total Suspended Matters (TSM) in the water of Bagré Lake, the second biggest lake in Burkina Faso, where the concentrations are particularly heavy. Micro-organism find a favourable terrain in the suspended matters. The turbid waters which are absorbed or […]
Sentinel-2 is a brand new and complex system, it is not a full surprise if it is experiencing some glitches. ESA is publishing weekly status reports, and the last two ones quote an issue with the mass memory. From weekly report #11, 24 Oct – 30 Oct 2015: The spacecraft has experienced this week an anomaly […]
=> The SMAC coefficients for Sentinel-2A are now available, and have been added to the CESBIO repository for SMAC coefficients. These coefficients were computed and checked by CNES colleagues in the Optical Measurement Physics service. If you happen to use these coefficients in your work, please thank CNES and CESBIO for providing them.As already said in an earlier […]
=> With the new availability of repetitive image time series after atmospheric correction over France from the Theia Land Data Centre, it is now possible to imagine the automatic production of land cover maps continuously with the availability of new images. In the framework of the SYRHIUS project, a prototype was developed at CESBIO to assess the […]
=> Voilà, it’s over, the THEIA team completed the processing of SPOT5 (Take5) level 1C and level 2A data. The time series are now available for download on our server : https://spot-take5.org I have counted nearly 3000 level 2A products, and even more level 1C, as we only issue the Level 2A product when the […]
=> Among the sites observed by SPOT5 (Take5), there was the Baffin Island, in the North of Canada. The cloud cover was very high on that site, but it still let us observe the snow melt over land, and the sea ice disappear. As you will see below, it is fascinating to see how the […]
My colleagues have processed two more weeks of SPOT5 (Take5) data, until beginning of Septembre. These data are now available on http://spot-take5.orgThere is only one more week to be processed.
After more than a week of inaccessibility, my colleagues were able to tune the configuration of the distribution server so that it passes through CNES security filters (if I understood well). So, good news, SPOT (Take5) data are is back on line ! http://spot-take5.org Après plus d’une semaine d’inaccessibilité, mes collègues ont réussi à remettre […]
Update 17/09/2015 : still not working, little hope to resume before Monday. The cause has been clearly identified, CNES security filter… Once again SPOT (Take5) distribution server is not accessible. The security filter at CNES is suspected, but we hope to resume activity soon. Please excuse us for these too frequent difficulties with this server. […]
