KEY WORDS: Global, Regional, Environment, Land cover, Satellite mapping, Satellite monitoring, SAR monitoring 
ABSTRACT 
Recent advances in geomatics technologies of satellite remote sensing, geographic information systems and global positioning 
systems, accompanied by development of international standards for remote sensing data and derived products, modernization of 
remote sensing data archives and establishment of international remote sensing data networks, have created new opportunities for 
land cover mapping and environmental monitoring at regional and global levels. These new developments are also bringing the 
remote sensing methodologies for land cover mapping and environmental monitoring closer together. It is proposed that both 
should be sharing the same comprehensive land information databases. Selected ongoing and planned regional and global land 
cover and environmental monitoring programs at the regional and global levels are briefly described. The paper concludes by 
emphasizing the need for better international coordination of regional and global land cover mapping and environmental 
monitoring programs. 
RESUME 
Les développements technologiques récents en géomatique (télédétection satellitaire, systémes a référence spatiale et systémes de 
positionnement globaux) combinés à l'élaboration de normes internationales pour les produits, archives et réseaux de télédétection 
ont créé de nouvelles opportunités en cartographie de l'utilisation des sols et en suivi environnemental, aux niveaux régionaux et 
planétaire. Ces nouveaux développements ont aussi pour effet de rapprocher les domaines de la cartographie des sols au moyen de 
la télédétection et le suivi environnemental car ils partagent désormais des banques de données communes. Cet article traite de 
l’utilisation de la télédétection satellitaire à des fins de cartographie de l'utilisation des sols et de suivis environnementaux à 
l'échelle régionale et planétaire, en s'appuyant sur des cas précis. En guise de conclusion, nous soulignerons la nécessité d’une 
meilleure collaboration internationale au niveau des programmes de cartographie des sols et du suivi environnemental. 
KURZFASSUNG 
Neuentwicklungen in der Informationstechnologie im Bereich der Satelliten-Fernerkundung, der Geographischen 
Informationssysteme und der Globalen Positionssysteme haben neue Perspektiven für die regionale und globale 
Landnutzungskartierung und Umweltüberwachung erôffnet. Dazu haben insbesondere die Entwicklungen in Bezug auf die 
internationale Standardisierung von Fernerkundungsdaten und -produkten, die Modernisierung von Datenarchiven und das 
Errichten von Datennetzwerken in der Fernerkundung entscheidend beigetragen. Diese Neuentwicklungen im Bereich der 
Landnutzunskartierung und der Umweltüberwachung haben die Fernerkundungsmethoden in diesen beiden Gebieten einander 
näher gebracht, da in beiden Anwendungsbereichen auf die gleichen Landinformationsdatenbanken zurückgegriffen werden. 
Ausgewählte regionale und globale Landnutzungs- und Umweltüberwachunsprogramme werden kurz vorgestellt. Zum Schluss 
wird die Bedeutung für eine verbesserte internationale Koordination der regionalen und globalen Kartierungs- und 
Umweltüberwachungsprogramme hervorgehoben.
