Abstract

AbstractThe 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 initial version of the system was delivered in March 1999, the validation of the data layers was completed in July 1999, and the system has been used operationally at the Manitoba Centre for Remote Sensing since 2000. In this paper, the authors describe GeoComp-n and the wide range of products that are generated through its operation.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 GeoComp, mentionnons une architecture de système modulaire, une GUI entièrement fonctionnelle et un format de produit de données réorganisé. Le système a été livré dans sa version initiale en mars 1999, la validation des couches de données a été complétée en juillet 1999 et le système a été utilisé de manière opérationnelle au Centre de télédétection du Manitoba à compter de 2000. Dans cette communication et dans celle qui l'accompagne, nous décrivons le nouveau système et la gamme étendue de produits qu'il permet de générer.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
