The PlanetWatchers analytics platform combines SPOT optical and TerraSAR-X radar imagery to detect changes in forest structure and biomass. Radar imagery delivers reliable information regardless of cloud cover or fog.
The TerraSAR-X radar imagery is extremely sensitive to leaf loss in the canopy, a major symptom of various forest health conditions. 2017 SPOT imagery allowed differentiating areas of multiple Eucalyptus clones and was used as a calibration for the radar data.
