C’est fait, Sentinel-2A est en orbite. Il a commencé à dialoguer avec ses stations de contrôle et a déployé ses panneaux solaires. Il faudra quelques jours pour vérifier et configurer la plate forme avant d’allumer l’instrument et de réaliser les premières acquisitions. Félicitations aux équipes de l’ESA, d’Airbus et des industriels associés à la fabrication du […]
Patience is not my best quality. For instance, regarding the availability of Sentinel-2 data, I even had the orbit of two satellites changed to obtain time series quicker :). So you cannot imagine how happy I will be to watch Sentinel-2’s launch tonight, and how even my alarm at 2:30 am will sound as a […]
ESA and CNES are glad to announce they just opened the new distribution site for SPOT4 (Take5) and SPOT5 (Take5) with a brand new look and feel compared to the previous SPOT4 (Take5) site. All the SPOT4 (Take5) data are available and may be downloaded, but the SPOT5 (Take5) site is almost empty (except for […]
=> The CNES THEIA distribution site was closed for 3 weeks for renovation works. It just reopened with a new address : It is possible again to downloat the L2A LANDSAT data over France. Besides anan enhanced look and feel, there are two new possibilities : As it is a new version, you might […]
=>Après 3 semaines de fermeture pour rénovation, l’atelier de distribution THEIA réouvre avec une nouvelle adresse : Vous pouvez de nouveau télécharger des données LANDSAT sur la France. Outre une interface plus complète et encore plus moderne, cette nouvelle version apporte deux grandes nouveautés : Cette version étant nouvelle, vous aurez probablement des suggestions […]
Everything is set to start SPOT5 (Take 5) operational production of L1C products today (L1C products are ortho rectified images expressed in Top of Atmosphere reflectance). The Level 2A production will start a couple of days later, when all the L1C of April and May are produced (L2A products provide surface reflectances and cloud and […]
=> I had sometimes used the following home made logo for SPOT (Take5) experiments : the Paul Desmond standard is indeed based on a 5 beat rhythm, which is symbolized by the « 5 » on the time signature of the music score. The number 4 means that the beat corresponds to quarter notes. But the 4 […]
=> Attention, ce post contient des termes techniques J’avais utilisé parfois le logo suivant et tout à fait artisanal pour Take5 : le morceau Take5 de Paul Desmond est en effet un morceau sur un rythme à 5 temps, d’où le 5 sur l’armure. Le chiffrage de la mesure comporte également un dénominateur égal à 4 […]
=> Summary : all the SPOT5 (Take5) scenes acquired from May the 29th to June the 2nd were lost. All sites are affected. Please accept our apologies ! A few other dates were also lost, see the list below. Usually, users of satellite images are not aware of all the work to maintain, program, configure a […]
