London MaP


London Motion Map Program (MaP) is designed by Telespazio VEGA to provide monitoring of ground motion in London and beyond.

We use Persistent Scatterer InSAR (PSI) with high resolution satellite imagery to identify surface movement with millimetric precision. Through the technology, we are also able to understand how much each major underground infrastructure is affecting London’s ground surface, including movement interaction between different major underground infrastructures to clarify liabilities. As part of this work, Telespazio VEGA has developed a baseline survey to keep monitoring in the future quickly and effectively.


The types of past major infrastructure projects that could have benefited from this technology include the Olympic Village in Stratford, Crossrail 1 and the Northern Line extension. Looking to the future, projects including the Thames Tideway Tunnel, HS2, Crossrail 2, and further London Underground extensions could all significantly benefit from the insight that London MaP technology offers.

Addressing the Infrastructure Lifecyle

  • Planning & Design Phase
    • Risk planning management:
      • Full survey for identification of sensitive areas to movement
      • Prior movement detection to clarify liabilities in case of construction-induced movement
  • Construction Phase
    • Measuring beyond the reach of in-situ instrumentation along track
    • Cost-effective survey just after construction in settling areas
    • Complementary and independent measurements
  • Operations & Maintenance
    • Long-term monitoring after in-situ instrumentation has been removed
    • Planning of surveying campaigns for maintenance


The baseline dataset analysis is already available as an off-the-shelf product with quick delivery providing high resolution surface motion for the London area from 2011-2015 from the COSMO-SkyMed satellite. Areas of Interest can be purchased from Telespazio VEGA at very competitive prices.
