Archived SAR imagery is processed to measure retrospective surface motion
Satellites available for historical analyses
Synthetic Aperture Radar (SAR) satellites have been imaging the Earth since 1992.
By simply providing us with your area and period of interest, we can determine which imagery archive is already available for a back 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
