Abstract
The paper describes algorithm development for tree height
retrieval in the boreal forest zone from TanDEM-X
interferometric imagery. A set of 8 TanDEM-X pairs was
acquired during summer and autumn 2011 over southern
Finland in order to evaluate the potential tree height
retrieval performance for this space-borne instrument.
Another focus of the study was evaluation of seasonal
dependence of interferometric signature of boreal forest.
The obtained results are compared to our previous studies
on tree height retrieval with the airborne DLR E-SAR
instrument in the same area. The obtained results show
good potential of TanDEM-X in forest mapping when
external terrain elevation model is available, though
accuracy seems to be somewhat lower compared to airborne
instruments due to increased noise.
