In agriculture, biomass
estimations are a key parameter in predicting crop yields.
This information is also useful for quantifying changes in landscape
structure and processes over time.
SAR images have been used to produce above-ground woody biomass
maps for relatively homogenous northern hemisphere forests and tropical
forests located in Central and South America.
Results from our research have demonstrated that SAR can also be
used to quantify biomass in more heterogeneous coastal environments
in northern Australia.
An AirSAR image and survey data, for a test site at the Mary River
in the Northern Territory, were used to produce a biomass map.
Imagery correlated well with the field sites data, which were in
a variety of Paperbark (Melaleuca) forests and woodlands.
Biomass values ranging from (freshweight) 20 ton/ha to 600 ton/ha
have been mapped.
