Figure 3: This map shows the ground motion results in the North German Plain (background image: two Landsat 7 pan satellite images recorded in Mai 2000). Green points indicate stable areas, blue points show uplift and yellow to red points show subsidence. The marsh areas along the North Sea coast and the rivers Elbe and Weser are very well visible with the PSI data showing subsidence with values between 1 and 7 mm/year (blue line: boundary between marsh and Geest)
