Cette mission est essentielle pour lever les barri\u00e8res techniques et financi\u00e8res, permettant ainsi aux acteurs locaux de b\u00e9n\u00e9ficier des derni\u00e8res missions spatiales (Spot, Pl\u00e9iades Neo).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Les \u00e9changes ont soulign\u00e9 l\u2019<strong>importance structurante de ces dispositifs d\u2019acc\u00e8s aux donn\u00e9es<\/strong>, maillons essentiels entre les infrastructures spatiales et les usages op\u00e9rationnels. La <strong>capacit\u00e9 \u00e0 p\u00e9renniser DINAMIS appara\u00eet ainsi comme un enjeu cl\u00e9<\/strong> pour garantir un acc\u00e8s continu et mutualis\u00e9 aux images satellitaires.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dans cette perspective, les modalit\u00e9s d\u2019acc\u00e8s pourraient \u00eatre progressivement enrichies afin de faciliter et d\u2019<strong>automatiser l\u2019acc\u00e8s aux images<\/strong>, et leur int\u00e9gration dans les cha\u00eenes de traitement et les workflows op\u00e9rationnels, notamment ceux mobilis\u00e9s dans des services comme <strong>Cosmeo<\/strong>. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">L\u2019objectif est de rendre l\u2019information plus fluide et plus directement exploitable, des analyses ponctuelles au suivi r\u00e9gulier des dynamiques c\u00f4ti\u00e8res.<\/p>\n\n\n\n<h4 class=\"wp-block-heading has-text-color has-link-color wp-elements-3\" style=\"color:#cc9605\">Cosmeo : des services op\u00e9rationnels au service du littoral<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Parmi les interventions, <strong>Valentin Pillet (i-Sea) <\/strong>a pr\u00e9sent\u00e9 plusieurs travaux d\u00e9velopp\u00e9s dans le cadre de Cosmeo, soutenu via le programme France 2030 par le CNES.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">L\u2019usage du <strong>Deep Learning appliqu\u00e9 aux images satellitaires THRS<\/strong> permet de produire des informations environnementales directement exploitables pour la gestion du littoral, notamment :<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>la <strong>cartographie fine des habitats sensibles<\/strong>, comme les <strong>herbiers marins<\/strong> ;<\/li>\n\n\n\n<li>le<strong> suivi des usages<\/strong>, dont la<strong> fr\u00e9quentation nautique<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Ces approches illustrent la mani\u00e8re dont la donn\u00e9e satellitaire, une fois trait\u00e9e, devient un support concret d\u2019aide \u00e0 la d\u00e9cision pour la pr\u00e9servation et la gestion des \u00e9cosyst\u00e8mes c\u00f4tiers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Au-del\u00e0 de ces premiers cas d\u2019usage, les \u00e9changes ont mis en \u00e9vidence une dynamique vers des <strong>services plus int\u00e9gr\u00e9s et plus flexibles, combinant production syst\u00e9matique
