=> As for LANDSAT 8 a few weeks ago, we just produced the level 2A products for the LANDSAT 5 et LANDSAT 7 data acquired above France from 2009 to 2011. This data set will be released in a few days, when its transfer to the distribution server has ended. The MUSCATE team took charge […]

The second « Sentinel-2 for science » symposium , organised by ESA, took place in italy late may 2014. More than 400 future Sentinel-2 users participated, which is a record for a conference organised by ESA at ESA premises. Compared to the first Sentinel-2 users workshop, it turns out that most of the talks were based on […]
=> More than 10 years ago, on the Crau plain, in Provence, CNES set up an automatic calibration station to measure the atmospheric optical properties and the surface reflectances. This station, named ROSAS (RObotic Station for Atmosphere and Surface), is at the top of a 10 meter mast, and is equipped with a CIMEL instrument […]
=> It is our great pleasure to announce that the LANDSAT 8 level 2A data produced by THEIA are available at the following address. http://theia.cnes.fr/ The available data are all the data acquired by LANDSAT over France, for which a sufficient number of cloud free pixels were available. They were processed to Level 2A : […]
=> That was fast ! The processing of all the LANDSAT 8 images taken above France in 2013 took less than 15 days. The first LANDSAT 8 images were taken in April 2013. The MUSCATE team processed the data for the THEIA land data center, using CNES computing center. A few more days will be necessary […]
=> As you may know, we have been selected for ESA’s project « Sentinel-2 Agriculture ». Among the tasks we must fulfill, we have to ask the users about their needs concerning the use of Sentinel-2 time series to monitor agriculture, and of course we need to write a synthesis. ESA had already distributed a questionnaire at the […]
=> At the beginning of the week, the MUSCATE prototype processing center of THEIA started processing the LANDSAT 8 data available in France. The processing started with the 2013 data, which will be transformed into Level 2A products. As for SPOT4 (Take5), the level 2A products are expressed in surface reflectance after atmospheric correction, and […]
=> As said in a previous post, we are testing various methods of level 3A production, using SPOT4 (Take 5). The Theia Land Data Center will the use these methods to process Sentinel 2 data. In case you did not click on the link above, let’s recall that the level 3A products are monthly composite […]
