Satellite Based Ground Deformation Monitoring
In urban tunnelling projects, ground deformation control and monitoring are important to guarantee that the different infrastructure assets crossing or adjacent to the tunnel alignment and other new build elements are not affected by the construction activity in the short or long term.
Radar satellite interferometry (InSAR) is a non-invasive surveying technique which is able to measure millimetric motion of terrain structures over wide areas and brings to the user a comprehensive, consistent and periodic vision of ground deformation without any need to access the site.
ATLAS is a Sixense InSAR solution applied to Crossrail I and The Elizabeth Line in London. After a brief introduction to the technique, this presentation will detail the application of monitoring of different phases of the project, highlighting the added value to the parties involved.
