DEFORMATION MONITORING BY SATELLITE

TRE-ALTAMIRA's mapping services can measure ground motion via satellite with millimeter precision. It does not require any infrastructure.

All structures above tunnels and underground excavations are continuously and precisely scanned and their movements and accelerations are monitored. This information can be easily displayed and analyzed in TREmaps™ online webGIS service.


Monitoring surface movements dating back to 1992

Resolving allegations of subsidence

In-situ displacement measurement during the design phase

Follow-up during construction and operational phases

To observe the state of collapse and movement of structures
