A new generation of data to monitor landscapes across the tropics:
The Copernicus Programme

Space Component
In-Situ Component
Services Component
Copernicus (formerly known as GMES) is a European space flagship programme of the European Union
Provides the necessary data for operational monitoring of the environment and for civil security
ESA coordinates the space component
COM coordinates the Service and In situ components

Data from Sentinel-2:
5 D(imension) improvement
1. Spatial detail: up to 10m = single large trees, roads, houses
2. Revisit/Coverage speed: 290km broad in 1 overpass = 5 days revisit at the equator (with 2 satellites)

December 2015
• Kalimantan Indonesia
• Several clear images
• Possible applications
• Type of forests
• Clear cut detection
• Flood monitoring
• Fires on last images
• Water turbidity
