(English version here) Peu de pays sont plus éloignés de la France que l’Australie. La carte d’occupation des sols dont nous parlons aujourd’hui concerne l’État du Victoria au Sud-Est de l’Australie. Cet État est quasiment diamétralement opposé à la Turquie avec des latitudes autour de 37°S et des longitudes autour de 145°E. Nous avons reproduit […]
(French version here) It would be difficult to be farther away from France than Australia. In fact, the map we’re talking about today is of the State of Victoria in Australia, which is roughly diametrically opposed to Turkey with latitudes around 37°S and longitudes around 145°E. What we have done is reproduce the methodology that […]
A good news for German users of Sentinel-2 data ! You might have already read on this blog that the German Aerospace Center, DLR became a member of MAJA development team in 2016. For instance, they provided the nice cirrus correction method. One of the team objectives was also to implement MAJA within DLR’s […]
In the framework of an open call Science4society funded by ESA, researchers at CESBIO have implemented a surface water detection algorithm from radar data Sentinel-1 on a cloud computing system. An API developed by Geomatys and JeoBrowser, two Information Technologies companies in France, is used to send the resulting surface water masks to a smartphone […]
In preparation for the next Pan European high resolution snow and ice monitoring service, I have upgraded the let-it-snow (LIS) processor to enable the computation of the fractional snow cover (FSC) within the pixel. So far LIS was only used to compute a « binary snow mask » (in fact ternary: snow, no-snow, cloud). However, the EEA […]
=> Comme nous l’avions annoncé en Novembre, le centre de production MUSCATE de Theia rajoute progressivement des zones au Sahel, qui sont affichées sur l’image ci-dessous. Les données sont traitées à partir de décembre 2016, ce qui nous fait une grande quantité de données à traiter. Nous avons donc commencé avec les tuiles les plus […]
=> As we had announced in November, the MUSCATE production centre in Theia is gradually adding areas in the Sahel, which are shown in the image below. The data are processed from December 2016 onwards, which means that we have a large amount of data to process. We started with the most westerly tiles, in […]
