Abstract
The Geocoding and Compositing System (GeoComp) developed at the Canada Centre for Remote Sensing (CCRS), Natural Resources Canada, has been processing Advanced Very High Resolution Radiometer (AVHRR) data from the United States National Oceanic and Atmospheric Administration (NOAA) series of satellites since 1992. GeoComp (Robertson et al., 1992) was designed to produce systematic, map-compatible, multi-date composite images over large areas with reduced or no cloud content. In 1995, a revision of the original system was proposed to improve the design based on experience gained from the system's operation, to incorporate many advances in computer hardware, and to introduce value-added products resulting from the research that used GeoComp. The new system was called GeoComp-n for the "next generation" of GeoComp processors. Technical improvements designed into GeoComp-n include a modular system architecture, a fully functional operator graphical user interface and a revamped data product format. The initia... Le Centre canadien de télédétection (CCT) utilise depuis 1992 le Système de géocodage et de composition (GeoComp) pour le traitement des données de la série des satellites porteurs de radiomètres perfectionnés à très haut pouvoir de résolution (AVHRR) de la National Oceanic and Atmospheric Administration (NOAA) des États-Unis. Le système GeoComp (Robertson et al., 1992) a été conçu pour produire des images composées multidates systématiques utilisables en cartographie couvrant de grandes étendues et ne comportant que peu ou pas de nuages. Une révision du système original a été proposée afin d'en améliorer la conception en fonction de l'expérience acquise à l'exploitation pour y intégrer de nombreux progrès réalisés en matière de matériel informatique et pour introduire des produits à valeur ajoutée résultant de recherches effectuées d'après des produits du GeoComp. Le nouveau système a été désigné GeoComp-n pour « nouvelle génération »de processeurs GeoComp. Parmi les améliorations techniques intégrées au...Keywords
