TRE ALTAMIRA is the largest InSAR group worldwide. With over 15 years’ experience, we are globally recognised as leader in measuring ground motion with millimetric precision. We provide displacement measurements and mapping solutions from satellite radar data (InSAR technology) that are used in a variety of sectors, including oil & gas, mining, civil engineering and geo hazards
 
TRE ALTAMIRA is a CLS group company with offices in Milan (Italy), Barcelona (Spain) and Vancouver (Canada).

 

Monitoring surface displacement from satellite

Satellite data can provide high quality, remotely sensed measurements of surface displacement.

Why are satellite radar data useful?

  • Time-lapse analysis: to millimeter precision of surface displacement

  • Remote measurements: no in situ equipment required

  • Single target analysis: for structures and local phenomena

  • Wide-area understanding of movements

  • Historical analysis: for site characterization

  • Monitoring: during construction and maintenance stages

  •  Complement: conventional surveys

TRE ALTAMIRA: At the forefront of technology with SqueeSAR™

SqueeSAR™ provides thousands of identified natural measurement points over an area of interest and their displacement in time. The SqueeSAR™ point density is much higher than the density of benchmarks in any other conventional geodetic network.

SqueeSAR™ for tunneling projects

Useful, cost-effective applications can be utilized within infrastructure/tunnelling projects.

  • During the initial design stage, SqueeSAR™ contributes to the analysis and study of an area of interest with a synoptic view of local dynamics. 
  • By mapping the temporal evolution of surface displacement during the construction stage, engineers gain a fuller understanding of the relationship between ground works and the onset of any related surface movement.
  • Finally, regular monitoring during operation allows engineers to identify displacement (subsidence or uplift) that could indicate structural weaknesses, or threaten infrastructure.
  • Subsidence maps also provide data for legal disputes concerning damage claims.

 

Key projects within this sector:

Canada Line: Rapid transit system in Vancouver.

Seven-year ongoing project during design, construction and operation stages

Biannual reporting activity

High speed Milan to Naples Railway: Railway tunnel and underground station in Bologna.

Analysis carried out during/after the construction stages to verify the effect of ground works on the settlement.

Venice-Trieste Railway Line:  Northern Italy

Analysis during preliminary design for the assessment of the planned route.

Scope of analysis to identify surface movement and integrate results with geological studies and geotechnical surveys.

SS 106 Jonica - National Highway:  Southern Italy

Analysis during design and construction stages to reconstruct past surface movement patterns along the alignment and identify surface displacement caused by tunneling.

Area covers 55 km of road, including 22 km of underground tunnels.
