Lesson 7. Forest monitoring
Optical satellite data have been used successfully to map fire scars and post-fire recovery, but are limited by cloud cover. C-band space-borne radar can 'see' through cloud, and has the potential for assessing the extent and severity of wild fire impacts, provided the effects of soil moisture and low vegetation is taken into account. This lesson shows how a time series of SAR images can be used to monitor both deforestation and vegetation recovery after forest fires. The synergy with optical data is demonstrated through the use of Landsat imagery. The importance of satellites for global fire monitoring is also shown, using example data from A/ATSR.
Level: Intermediate. Requires some understanding of SAR remote sensing theory.
