=> One of my colleagues from CESBIO and CNES, a specialist in automatic classification methods and creator of free software named after Monteverdi’s opera, told me that during his last Sunday walk in the Bouconne forest, the trees were being devoured by caterpillars. By listening, you could even hear them nibbling on the leaves. Even […]

The European Environment Agency (EEA) has selected a consortium led by Magellium to implement the next Pan European high resolution snow and ice monitoring of the Copernicus Land Monitoring Service. This future service aims to monitor three variables at 20 m resolution over the tiles displayed above: All products should be generated from atmospherically corrected […]

In a remote sensing study published in Nature, the authors claimed that they used « 101 CPU-core years of computation (..) within the Google data centres ». This made me wonder what could be the carbon footprint of such a study?. I estimated that it should be 65 tonnes of carbon dioxide, but a Google engineer replied: […]

Two years ago I posted an animation of the snow cover area evolution near Zermatt, Switzerland from Sentinel-2 L2A data processed by LIS. From this time series of snow maps I generated a snow cover duration map and then I added the glacier outlines from the Randolph Glacier Inventory 5.0. I was satisfied by the […]

=> Nous avons commencé à distribuer MAJA gratuitement en juillet 2017, il y a moins de deux ans, et le logiciel a déjà été téléchargé plus de 1000 fois (1068 précisément aujourd’hui). Cela représente en moyenne plus de deux téléchargements par jour de semaine, et ces dernières semaines, nous avons atteint environ 4 téléchargements par […]

Récemment j’ai extrait la carte de la durée de l’enneigement faite à partir des produits neige Theia pour la Direction Départementale des Territoires de Haute-Savoie (DDT 74). Pour cela j’ai traité quatre tuiles Sentinel-2 ce qui couvre une bonne partie des Alpes du Nord. En inspectant cette image mon œil a été attiré par des […]

=> We started distributing MAJA as a free software in July 2017, less than 2 years ago, and it already reached 1000 downloads (1043, as a mater of fact). MAJA was in fact downloaded twice per working day, and in the very last weeks, we had about 4 downloads a day ! Of course it […]

The Sen2Agri system was just released in version 2.0. As the project is now terminated and will not receive more funding from ESA, V2_0 is the final version, apart maybe for a few bug fixes. Sen2Agri is a very complete ground segment that automates download and processing of Sentinel-2 data to obtain multi-temporal syntheses, crop/non crop, […]

Recently I generated one year of snow maps from Sentinel-2 in the Canadian Rockies for a talented colleague who is working on the numerical simulation of the snow cover at high-resolution with an exciting new hydrological model. The area is not covered by Theia, hence I used Start_Maja to generate the L2A products and then […]
