A new paper on tree height estimation from TanDEM-X data has just been published in Remote Sensing of Environment. The article finds that tree height can be predicted using TanDEM-X metrics (backscatter, bistatic coherence, and interferometric height) in the sparse forest patches of the Arctic treeline zone at the transition from forest to tundra. Taking into account the global coverage of bistatic TanDEM-X data acquired for the global digital elevation model, the paper shows the potential for quantifying the tree height in small forest patches along the entire circum-Arctic treeline zone.
