=> As you already know if you have been following this blog, our L2A method for cloud detection and atmospheric correction, named MACCS, makes a large use of multi-temporal information. It assumes that over lands, the surface reflectances in the blue do not change quickly with time, except on some exceptions that have to be […]
LANDSAT 8 A force de parler de SPOT5 (Take5), il ne faudrait pas oublier que le centre de traitement MUSCATE du centre de données THEIA continue à traiter opérationnellement les données LANDSAT 8. Le rythme de production a même accéléré, puisque les données acquises par LANDSAT 8 du 1er au 15 avril sont déjà en […]
Airbus Defence and Space (Ex Spot Image), produces every week the new data downloaded from the satellite to level 1A (Thanks Myriam !). We have now received nearly two entire cycles of SPOT5 (Take5) images, which means that we have our first time series, although made of only two dates ! Our processing center, MUSCATE, within […]
=>Voici une copie d’écran de la première image SPOT5 (Take5) du lac Victoria en Ouganda, après ortho-rectification (L1C), superposée à une image similaire acquise par LANDSAT 8. Les deux images se superposent apparemment très bien, même si nous devons procéder à une validation plus rigoureuse. Ceci dit, même si ce n’est pas une surprise, […]
=> Here is a screen copy of the first SPOT5 (Take5) ortho-rectified image (L1C) from the Lake Victoria image in Uganda, registered with a similar product from LANDSAT 8. Both images match very well, but we need to validate that much further. However, although it is not a surprise, it is good news that processors […]
The processing of SPOT5 (Take5) data is based on a prototype ground segment and involves prototype processors, and we have lots of configuration data to produce for each of the 150 sites. Moreover, to reduce exploitation costs, the processing at Airbus DS for Level 1A, and then at CNES (L1C and L2A) are launched only […]
=> The first set of SPOT5 (Take5) images was acquired yesterday, 8th of April. Here is one of the images, processed by Airbus Defence and Space at Level 1A. This image has nothing special in itself, as it is only one of 12 000 000 SPOT5 images, but it is still the proof that everything […]
=>La première série d’images de SPOT5 (Take5) a été acquise hier, le 8 avril. Voici un premier exemplaire de ces images traitées au Niveau 1A par Airbus Defense and Space. Cette image n’a rien de spécial en elle-même, ce n’est que l’une des 12 000 000 d’images acquises par SPOT5, mais elle prouve toutefois que […]
Update : I was wrong, 8th of September is a day #1 (one day error for me, one for the operation team). Calendar has been updated. Sorry !I have added a calendar page to the SPOT(Take5) menu, which gives you the day number in the take5 cycle for each SPOT5 (Take5) site, and gives you […]
