Historical Analysis

Providing retrospective surface motion maps and displacement time series of any single point measurements to millimetre accuracy.

From national to regional, from wide-area to single structure, TRE ALTAMIRA's analysis options meet the scale you need in a cost-effective way. Historical analyses are particularly encouraged for:

  • Land inventories
  • Site selection processes
  • Understanding the response to ground suface instabilities and active working (e.g. subsidence claim assessment)
  • Calibrating risk models
