Application of Envisat/ASAR for Monitoring of Tropical Forest Plantation Biomass in Indonesia

A study for SAR biomass mapping in tropical plantation forest in Indonesia is now undergoing by using Envisat ASAR images. This study is expected will fill the gap, since most of the existing SAR biomass studies in Amazon (global) and Indonesia Radar Experiment – INDREX (local) are mostly concentrated in tropical natural forest. In the first step, the study will explore the link between ASAR precision image (IMP) parameters with ground measurement parameters, namely : Mid Rotation Inventory (MRI) and Pre-Harvest Inventory (PRI). In the second step, the InSAR method will be applied. This will follows with the PolinSAR method in the last step. The paper presents the research framework and the preliminary result by using ASA_IMP_1P 4 February 2003 for application of radar biomass analysis in the precision image during the first cycle of the spatial information cycle. Further improvement will be made in the second cycle to be completed in 2004.
