RESTEC and partners designed a workshop in Indonesia and a training course in Japan with the aim to improve Indonesia’s capability of forest monitoring, transferring Japanese technologies and knowledge of analysing satellite data, particularly ALOS/PALSAR, and contribute to decision-making in forestry and carbon emissions in Indonesia. A one-day workshop and two-week training course were completed where participants shared very useful information. Eight Indonesian GIS/RS experts learned the basic theory of Radar sensor, in particular ALOS/ PALSAR, geometric and radiometric features of SAR and other basic knowledge. They also practised techniques and procedures using PALSAR observation data for forest monitoring and forest biomass estimation. With these techniques and knowledge, they can advance their research and operational forest-monitoring work more efficiently. Collaborators agreed that the training was useful and that these kinds of activities to improve Indonesian capacity should be continued.
