Funding: National, Industrial
Status: Completed
Research unit:
Remote Sensing (RSE)
Acronym: GRD

The GRD project is focused on ground movements related to landslides and other ground instability phenomena occurring in the Sierra Nevada area. It involves two types of activities:

A) Differential SAR interferometry (DInSAR): processing and analysis of single differential interferograms. This includes:

  •  The acquisition of SAR images from the sensors ALOS Palsar and ASAR Envisat.
  •  The SAR image preprocessing and the differential interferogram computation.
  •  The joint analysis of the interferograms, which involves the CTTC staff and the experts of the University of Granada.

B) Advanced DInSAR: Persistent Scatterer Interferometry (PSI). This includes

  •  The design of a redundant network of interferograms.
  •  The pixel selection.
  •  The estimation of the deformation velocity maps
  •  The estimation of the deformation time series.
  •  The joint analysis of the results interferograms, which involves the CTTC staff and the experts of the University of Granada.

 

Figure 1 illustrates an example of deformation velocity map superposed to an orthoimage.
