Zusammenfassung
Implementation of policies to reduce forest loss challenges the Earth observation community to improve forest monitoring. An important avenue for progress is the use of new satellite missions and the combining of optical and synthetic aperture radar sensor data. Monitoring of changes in tropical forest cover has relied predominantly on optical satellite sensors because of their relative ease of processing and interpretation and the
continuity of medium-resolution (10–30 m)
observations since the 1970s1,2. Spaceborne
synthetic aperture radar (SAR) data have
the advantage of providing cloud-free
observations, but these data have been
comparatively underutilized in operational
programmes1,2. It is rarer still for optical
and SAR data to be used in combination,
despite increasing evidence of the benefits of this approach.
