accès et utilisation de radarsat-2
DESCRIPTION
L’Agence spatiale canadienne fournit de l’imagerie satellitaire aux différents ministères fédéraux depuis le lancement de RADARSAT-1 en 1995. Avec la venue de RADARSAT-2 en 2008, l’utilisation et des applications en Observation de la Terre ont fait un bond important au sein du Gouvernement du Canada. La raison de ce succès est liée principalement à l’accessibilité de la donnée. L’emphase sur les produits à valeur ajoutée est aussi un facteur important à considérer. Les prochaines générations de satellites telles que la Constellation RADARSAT seront une source accrue de données qui nécessitera une infrastructure géomatique importante afin de rendre disponible la donnée à un plus large public.TRANSCRIPT
