Thematic and Land Subsidence Maps of the Lagoon of Venice from ERS SAR Interferometry

Within the Co.Ri.La. project 3.2 on Hydrodynamics and Morphology, interferometric radar images from the ERS-1/2 satellites from 1993 to 2000 have been used to generate a subsidence map of the Lagoon of Venice. The SAR interferometric land subsidence map pictures very well the different displacement rates of the various compartments of the Lagoon. The SAR interferometric displacement map is discussed in comparison to the levelling results available through the ISES project. A geocoded thematic map of the Lagoon of Venice at 30 m resolution is also presented.
