Satellite based ground and structure deformation monitoring made simple.
ATLAS™ is our InSAR solution for remote monitoring of ground deformation with millimetric accuracy.
Radar satellite interferometry (InSAR) is a non-invasive surveying technique able to measure millimetric motion of terrain structures over wide areas in both urban and non-urban environments. This technique is based on the exploitation of synthetic aperture radar images (SAR) acquired from satellite- sensors.
ATLAS™ uses raw data from satellite constellations that we process to deliver time-series ground motion data with a density of up to 20,000 pts /Km2
Stand alone or in conjunction with more traditional instrumentation it provides unique information about your site or infrastructure without any installation on the ground.
Archive of SAR data acquired (from 1992 onwards) is available and can be used to analyse and map ground movements that have occurred in the past. These retro studies inform of pre-existing vulnerabilities and make sure the construction design is suited for the existing conditions.
Furthermore, evidences from the past ground and asset behaviors are an effective tool for 3rd parties claims protection.
When using high resolution satellite images Atlas InSAR provides results with a resolution of 3m x 3m and a density up to 20,000 Pts/Km2 over very large areas.
This yields an unrivalled level of information to analyse and understand the situation and behaviour of your site whatever its size, infrastructure or the whole city.
Dewatering activities for example have shown on numerous occasions impacts over long distances, and Atlas InSAR measurements will enable a clear delimitation of the perimeter at risk and overcome the potential problem of loss of references for the ground instruments.
Atlas InSAR outcomes are measurement layers of many thousands to a few million measurement points depending on the nature of the surface.
While precise levelling is carried out in one specific area at a rate of around 100 points monitored per day, ATLAS™ can provide more than 20,000 measurements points per km2 in urban environments.
Precise levelling, Automatic Total Station and InSAR are complementary technologies and if properly deployed, the combination of the three can significantly lower the cost of ground deformation monitoring with richer delivery of information.
BEYOND™ Satellite is our web based delivery platform for all of your projects. With an architecture optimised for “big data”, visualisation and analysis of millions of data points is smooth and intuitive.
For urban or rural environments, Atlas InSAR yields outstanding outcomes for monitoring almost any type of asset. Buildings, airports, ports, dams, roadways, railways, mines...
For monitoring settlement induced by underground excavation and/or dewatering (tunnel construction, mining…) Atlas InSAR stands out. Its ability to monitor simultaneously large areas with high density and accuracy is absolutely unique and highly valuable.
No wonder Atlas InSAR is becoming a standard in ground & structure deformation.
