Forest loss and disturbance alerts
Landsat, Sentinel-2 and Sentinel-1 time series are classified to map annual loss and near-real-time disturbance, with radar used where cloud blocks optical sensors.
GCRI · Biodiversity Nexus
Satellites observe forests, wetlands, coasts and the ocean surface repeatedly and across borders, which field surveys cannot. Earth observation maps ecosystem extent, change and some aspects of condition, and it gives a consistent record for places where no one monitors on the ground.
Earth observation and remote sensing gather information about the Earth’s surface and atmosphere from airborne and spaceborne sensors. They provide consistent, repeatable measurements over areas that are hard to monitor on the ground. In biodiversity and nature, climate and hazards and oceans and coasts, earth observation maps exposure, damage and environmental change across borders and sectors. It supports rapid assessment after disasters and long-term monitoring of risk drivers. The canonical description is on STEM Commons.
Landsat, Sentinel-2 and Sentinel-1 time series are classified to map annual loss and near-real-time disturbance, with radar used where cloud blocks optical sensors.
Radar and optical time series track flooding regimes, wetland extent and mangrove change, separating seasonal variation from conversion.
Spaceborne lidar and radar estimate canopy height and biomass, and spectral indices track phenology and stress as proxies for ecosystem condition.

Products are assessed against ground reference data using accuracy matrices and independent samples. Cross-calibration between sensors checks consistency over time.
| Kontrol bikin | How it is done |
|---|---|
| Accuracy assessment with area estimation | Maps are scored against a probability sample of reference points, and areas are adjusted for classification error |
| Cross-sensor consistency | Trends are checked across sensors and processing versions before they are reported |
| Field calibration | Structure and condition proxies are calibrated against inventory plots |
| Coverage reporting | Cloud, revisit gaps and missing scenes are reported as no data, not as no change |
Clouds, revisit gaps and mixed pixels limit what can be observed. Changes in sensors and processing can create artificial trends.
