This video shows all available Venµs images since launch over the Khumbu icefall near Mt Everest (109 images). The images are RGB composites of Level 1C bands 7,4,3 (5 m resolution) that were draped onto the HMA 8m DEM. How to do that? First download the Venµs images using theia_download.py, extract the region of […]

=> I left you in mid-July with an unbearable suspense: would the Bouconne oak forest, the real lung of the Toulouse conurbation, resist the caterpillar attack of which it was the victim? The gypsy moth is a small butterfly whose voracious caterpillar appreciates oaks. This year, the moth caterpillars have flourished in some areas of […]
=> Je vous avais laissés à la mi-juillet avec un suspense insoutenable: la forêt de chênes de Bouconne, véritable poumon de l’agglomération de Toulouse, allait-elle résister à l’attaque à la bombyx dont elle était la victime ? Le bombyx disparate est un petit papillon dont la chenille vorace apprécie les chênes, qui cette année a […]
=> The combined use of VENμS, Sentinel-2 and Landsat-8 data can increase the likelihood of obtaining cloud-free images or may allow detailed tracking of rapidly evolving phenomena. In order to facilitate this combination, the table below summarizes the correspondences between the spectral bands of the instruments. VENμS does not have a spectral band in the […]
=>L’utilisation combinée des données de VENµS, Sentinel-2 et Landsat-8 peut permettre d’augmenter la probabilité d’obtenir des images sans nuage ou de suivre de manière détaillée des phénomènes à évolution rapide.Afin de faciliter cette combinaison, le tableau ci-dessous présente de manière résumée les correspondances entre les bandes spectrales des instruments. VENµS ne comporte pas de bande […]

Venµs is a French-Israeli satellite mission which captures high resolution multi-spectral images every two days over selected sites. The Theia land data center is kind enough to provide L2A images (bottom-of-atmosphere), which can be easily downloaded by batch (see this tutorial). Here I selected all the images of a site near Mount Cook in the […]
