Russia is the nation with the largest forest area and its extent has been recorded using Earth Observation. Radar instruments on ERS as well as Japan's JERS-1 have been used to map 1.2 million square kilometres of forest across central Siberia, the largest project of its kind. Forest authorities used the land cover maps to update obsolete inventories and monitor reforestation efforts. This SIBERIA Project mosaic image shows forest stem volume and land cover classification across this vast region. For more information, click here
