Enhance button is a very common movies trope, where a character scrolls through some video footage or photos and asks a computer to enhance its resolution to an insane level of details, enabling solving crime mysteries and conspiracies of all sort with clues that were invisible in the original image. While this meme has been […]
The results presented in this blog are based on the published work : I.Dumeur, S.Valero, J.Inglada « Self-supervised spatio-temporal representation learning of Satellite Image Time Series » in IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, doi: 10.1109/JSTARS.2024.3358066. In this paper, we describe a self-supervised learning method to train a deep neural network […]
=> Several data access centres are being renovated at CNES, ESA, and their first versions often lack some of the features we need. Together with colleagues from CESBIO, we have made a presentation of the way we use remote sensing (RS) data: here is a text version of this presentation. Of course, there are as […]
=> Plusieurs centres d’accès aux données sont en train d’être renouvelés au CNES, à l’ESA, et il manque souvent dans les premières versions des caractéristiques dont nous aurions besoin. Avec des collègues du CESBIO, nous avons fait une présentation au CNES de la manière dont nous utilisons les données. Voici une version écrite de cette […]
Pour certaines applications il est utile de connaître l’angle solaire au moment de l’acquisition d’un produit Sentinel-2. Par exemple pour notre chaine de détection de la neige LIS nous avons besoin de pré-calculer les ombres créées par le relief à partir d’un MNT. Cela nous permet d’améliorer la détection de la neige dans les zones […]
Le CNES a confié à la société SapienSapienS la réalisation de belles vidéos pour le grand public, qui expliquent de manière très didactique, et en moins de 5 minutes, différentes thématiques d’observation de la terre. Trois d’entre-elles font la part belle aux travaux du CESBIO, et je suis très fier d’avoir contribué à la première […]
Iota2 is constantly evolving, as you can check at the gitlab repository. Bugs fix, documentation updates and dependency version upgrade are done regularly. Also, new features are introduced such as the support of Landsat 8 & 9 images, including thermal images, or for what concerns us in this post, the support of regression models. In […]
The results presented here are based on published work : V. Bellet, M. Fauvel, J. Inglada and J. Michel, « End-to-end Learning For Land Cover Classification Using Irregular And Unaligned SITS By Combining Attention-Based Interpolation With Sparse Variational Gaussian Processes, » in IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, doi: 10.1109/JSTARS.2023.3343921. This […]
=> Update the 8th of January, 2024 : A new change in the interface from the Copernicus Dataspace on January the 2nd, implemented without prior notice, has caused a new interruption of our downloads, and the real time processing at THEIA, at a moment when no one was available to change things on the our […]
