Abstract :
The potential of TerraSAR-X imagery for forest cutting monitoring was experimentally investigated in images over Kuortane, Finland. In this study, 10 dual-polarised change detection indices were tested versus a ground truth of clearcuts done between the acquisition dates. Preliminary results suggest the decrease of entropy and the increase of coherence at X-band could be good change detection indices. Results were probably affected by adverse weather conditions during the acquisition of the second scene.
