Abstract :
Forest biomass mapping was studied in a site in northern Finland (latitude 66deg). Two JERS SAR scenes that were acquired in a dry period were used. Locally derived linear regression models between forest stem volume and L-band SAR amplitude produced correlation coefficients of 0.7. An earlier regression model, which had been derived in a site in southern Finland, produced under-estimates of approximately 50 m3/ha in a study site where stem volume varied between 0 and 220 m3/ha.
