By CTGuyane.fr and its partners
the trusted territorial program
A public service of excellence for environmental monitoring and decision support in French Guiana, built on European space technologies.
Satellite-Assisted Environmental Monitoring
SEAS Guyane is the reference territorial program for satellite observation in French Guiana. It provides data, indicators, and expertise for environmental monitoring, land-use planning, risk prevention, and decision support.
Our mission is to support public actors in their use of the platform and their upskilling, to develop local expertise and innovation, and to strengthen cooperation with the Guianas Plateau, the Caribbean, and the world's major forest basins. It thereby helps reconcile economic development with sustainable territorial management.
Thematic monitoring
Earth observation by satellite, mobilized to track territories and address the challenges of Amazonian and Caribbean ecosystems.
Deforestation
Monitoring forest cover change and detecting illegal logging along roads and waterways.
Water quality
Monitoring coastal and inland waters, detecting pollution and tracking eutrophication and turbidity.
Land-use planning
Mapping land-use change, urban planning, zoning documents, and infrastructure projects.
Risk management
Detecting vegetation fires, erosion and flood risk, monitoring ground movement and at-risk areas.
Human activity
Tracking illegal gold mining, monitoring industrial sites and infrastructure, and analyzing unregulated urbanization.
Thematic mapping
Producing thematic geographic maps for the environment, biodiversity, and institutional decision support.
