22. Processing difficulties - coregistration Coregistration of the area is not straightforward. (Resampling polynomial is not well-confined due to the incoherent water areas.) The placement of fine coregistration windows has been limited only to land areas. After quite some manual fine tuning, the results were satisfactory. The coordinates of the window centres have been stored in the file coreg_points.txt and introduced within the processing. FC_IN_POS doris card

23. InSAR and PSI processing 38 ERS-1/2 SAR images Image crop of 10200 X 2200 pixels has been processed 36 interferograms used for PS processing, some examples:

24. Processing problems -PSI PSC network – after applying the masking Masked areas over the sea

25. Preliminary results The first reasonable result of the descending stack processing Good coverage of Skagen town However, the main problem is the lack of coherent points on the main arm of the peninsula. This results in a weak connection of the tip of the peninsula to the main land. Many arcs are still rejected Therefore, the color differences between Skagen city and the rest of the area should not yet be quantitatively interpreted.

26. Preliminary results The points detected within Skagen city suggest that the highest subsidence rates are between the harbor area and the village The subsidence velocity of the harbour relative to the city is about 8-10 mm/year However, due to weak connection within the network the subsidence rate between Skagen city and the mainland is still not well defined We are currently trying different manual tricks to obtain at least some coherent arcs in this area.

28. Conclusions Interferometric processing OK (Problems in coregistration were solved) Coherent information over village and build-up areas Poor connection between coherent patches: many rejected arcs Improvement of connection still ongoing Relative subsidence of Skagen harbor detected of 8-10 mm/y
