Theia’s Landsat data are moving

In English Landsat THEIA

Olivier Hagolle, 14 septembre 2016

=> It is true that many of us can be moved by the Landsat L2A data produced by THEIA, but this time, the data were literally moved. The presently used downloading site http://theia.cnes.fr is being prepared to host Sentinel-2A data produced by the operational MUSCATE ground segment, and meanwhile, the prototype center goes on producing LANDSAT L2A data abovce France. However, their format is not compatible with the new server.As a result, LANDSAT data will stay hosted on the old server, whose address has just been changed. THEIA’s L2A LANDSAT data are now distributed at :

http://theia-landsat.cnes.fr

On this server, you will find the LANDSAT data acquired above FRANCE and oversea territories since 2009 for France, and since 2013 for overseas. The data are corrected for atmospheric effects and are provided with a cloud mask and a cloud shadow mask. They are split in 110*110 km2 tiles, and in Lambert 93 projection. When MUSCATE is ready, we will reprocess all LANDSAT 8 data with the new system, and will distribute them from the new server. This time, the data will be projected on UTM projection and the tiles will be the same as for Sentinel-2, to allow a better combined use.

Impact of the August 12, 2026 eclipse on photovoltaic electricity generation in Spain

Photovoltaic (PV) energy supplies more 20% of Spain’s total electricity, and this share hit a new high in July 2026 (28.3% of the nation’s monthly electricity mix). Some media outlets were concerned about the drop in photovoltaic power generation during the 12-Aug-2026 eclipse. Le Monde explained that « the drop is expected to be particularly pronounced […]

The missing link to valorize CESBIO’s applicative research works

=>  My colleagues at CESBIO are extremely creative! Over the past ten years, they have developed a wide range of new products and methods for extracting information from Copernicus data. They don’t just develop and validate the method on a few sites; they continue their work until they have produced data for the whole of […]

Le chaînon manquant dans la valorisation des travaux de recherche en télédétection

=> Mes collègues du CESBIO sont très créatifs ! Ils ont mis au point, au cours des dix dernières années, un grand nombre de nouveaux produits et de méthodes d’extraction de l’information à partir des données Copernicus (Sentinel-1 et 2). Et bien souvent, ils ne s’arrêtent pas à la mise au point de la méthode […]
