=> CNES just decided to extend the SPOT5 (Take5) experiment by one week until the 15th of September. This extension is a generous compensation for the loss of two periods of acquisition : Thanks to this extension, we will still get 5 complete months of data for each site, and about 30 acquisitions per site, every […]
The programming of the 2nd and 3rd of August acquisitions failed for a complex reason which is now understood, and should not happen again. Please remember that the programming is done fully manually, as SPOT5 is not on its nominal orbit and that it requires a lot of work from the teams at CNES to […]
While most CNES personnel is on vacation, the THEIA exploitation team is still producing data. A new batch of L1C and L2A SPOT5 (Take5) data has been uploaded to the server. All the data acquired until the 8th of July are now available. Have fun (either with your holidays, or with the Take5 data !) […]
=>Trois semaines de données supplémentaires viennent d’être ajoutées au serveur de distribution des produits Take5. Les L1C sont disponibles, les L2A sont prêts et apparaîtront sur le serveur d’ici peu (leur transfert prend du temps…). Les données acquises jusqu’au 24 juin sont donc disponibles ici : https://spot-take5.org. Les séries disponibles commencent à être suffisamment longues […]
=> Three more weeks of data (L1C) have been added to the SPOT5 (Take5) distribution server. The corresponding L2A data should appear very soon, but the dtata transfer takes a long time. The data acquired until the 24th of July are now available here : https://spot-take5.org. We are now starting to see very nice time series, […]
=> Several colleagues asked me about the apparent defect on the maritime part of Sentinel-2 first image. I would like to reassure you, it is not a defect, only a directional effect. Let’s explain it :- For each Sentinel-2 spectral band, 30 000 elementary detectors are necessary to obtain a field of view of 300km […]
=> Vous êtes plusieurs à m’avoir parlé du défaut apparent, visible sur la partie maritime de la première image de Sentinel-2A. Je voudrais vous rassurer, ce n’est pas un défaut, mais un effet directionnel. Je vous explique :- pour chaque bande spectrale de Sentinel-2, il faut 30000 détecteurs pour couvrir le champ de 300 km […]
