A private company, operating under a US federal license, was effectively told by the Trump administration to go dark over an active war zone. Planet complied. Vantor and BlackSky — both heavily dependent on US defense revenue — said they hadn’t even received such a request, because they were already tightly controlling access. The selective pressure lands precisely on the most open, most commercially accessible provider. That is not a coincidence.A private company, operating under a US federal license, was effectively told by the Trump administration to go dark over an active war zone. Planet complied.

Super-résolution 1 m a Madrid avec Sentinel-2 10m. Magique ! Tracking NRT!
Passer d’une résolution de 10 mètres à 1 mètre change radicalement la perspective du suivi agricole : on ne regarde plus une parcelle dans sa globalité, on observe ce qui se passe à l’intérieur même des rangs de culture. Ce saut qualitatif est possible grâce à l’algorithme S2DR3, un modèle de Deep Learning qui ne se contente pas d’agrandir les pixels, mais reconstruit l’information manquante. En s’appuyant sur les corrélations entre les différentes bandes spectrales de Sentinel-2 et en s’entraînant sur des images de très haute résolution, l’IA parvient à synthétiser une image à 1 m/pixel d’une précision étonnante.
