Abstract
Data from ALOS/Palsar and TerraSAR-X were used to estimate
forest biomass in Boreal forest zone in Finland. In the
study site in Heinavesi (forest biomass between 0 and 255
tons/ha), the HH-polarised component of dual-polarised
ALOS/Palsar produced biomass estimation accuracies (RMSE)
between 35 and 42 tons/ha. In the Kuortane site (biomass
0…188 tons/ha) the RMSE varied between 25 and 28 tons/ha.
Since only two winter-time scenes from TerraSAR-X were
available, TerraSAR-X results were very preliminary. The
phase of the HH-VV cross-coherence produced the highest
biomass-correlations among the TerraSAR-X derived
features. This produced a biomass estimation accuracy
(RMSE) of 49 tons/ha in the Heinavesi study site.
