Susanne Karg started her M.Sc. thesis on „Burn scar detection using polarimetric ALOS-2 time-series data“ in cooperation with DLR-DFD (Günter Strunz, Sandra Martinis). The aim of this thesis is to develop a change-detection approach using polarimetric SAR (PolSAR) data and, if suitable data is available, interferometric SAR (InSAR) data to detect fire scars. Within this thesis different polarimetric decomposition approaches and pixel-based classifications will be tested for their suitability to detect a recently burned region of interest. The variables which perform best will then be used for an object-based post-classification refinement.
Towards Earth Observation-supported identification of drought-resilient tree provenances in Bavaria
Recent drought years have raised concerns about the future vitality of different tree species in Bavaria. Focussing on European beech (Fagus sylvatica) in Bavaria as an example, drought impacts vary considerably, with pronounced decline in part of the stands while...
