Civil and urban engineering supported by high-precision satellite data
Infrastructure
Critical infrastructure—urban, civil, or transportation—is constantly exposed to geotechnical risks that can affect its operation, safety, and lifespan. At EOSAR Mexico InSAR technology to offer continuous, remote, millimeter-precise ground monitoring, providing key information for the planning, construction, operation, and maintenance of infrastructure projects.
InSAR technology allows for the detection of subsidence, differential settlement, structural displacements, and surface movements that, without early intervention, could escalate into structural damage, functional failure, or service interruptions.
InSAR applications for infrastructure
-
Subsidence monitoring in urban environments
We monitor gradual or localized subsidence in cities and towns, linked to water extraction, massive construction, or geological conditions.
-
Supervision of roads, bridges and highways
Technologies such as InSAR are used to detect deformations in soil and foundations, allowing maintenance to be prioritized and costly repairs to be avoided. This is especially important on mountain roads prone to landslides and other landslides. Continuous monitoring of unstable slopes helps identify gradual displacements and trigger early warnings, improving road safety and the resilience of road infrastructure.
-
Surveillance of railway tracks and railway platforms
We detect minimal movements in key areas (tracks, sleepers, embankments), especially in freight and high-speed corridors.
-
Geotechnical evaluation in civil engineering projects
We provide historical and current information on ground behavior to support construction designs, risk analysis, and feasibility studies.
-
Monitoring of linear and underground works
Ideal for tunnels, drainage networks, subway lines and urban utility cabling.
Key benefits
-
Millimeter detection of ground deformations.
-
Reduction of physical inspections and reactive maintenance.
-
Contribution to urban resilience and territorial sustainability.
-
Support for regulatory compliance and risk mitigation.
-
Visualization on interactive platforms with early warnings.
-
Historical coverage (since 1992) and current high-frequency monitoring.
Typical use cases
-
Cities with active subsidence due to overexploitation of aquifers.
-
Urban areas on soft soils, landfills or former lakes.
-
Railways with high traffic or old structures.
-
Critical infrastructure such as hospitals, schools or treatment plants.
-
Bridges and roads exposed to earthquakes, landslides, extreme rainfall, or mining activity.
Frequently Asked Questions:
How useful is InSAR for cities with subsidence?
InSAR is a highly effective tool for detecting and monitoring urban subsidence with high precision, thanks to the strong radar response in urban environments and its frequent monitoring capability. This allows governments and urban planners to design projects, prevent collapses, and target investments in critical sinking areas for more accurate and efficient solutions.
Can this data be used for design or maintenance projects?
Yes. We provide multi-temporal information for engineering design, geotechnical modeling, feasibility studies, and maintenance planning, with reports compatible with GIS and CAD platforms.
How frequently can analyses be delivered?
The monitoring frequency with InSAR depends on the satellite and project requirements. For example, Sentinel-1 provides imagery every 6 to 12 days, while commercial satellites can deliver daily acquisitions.
Can we receive alerts?
Yes. We offer customized threshold settings that trigger automatic early warnings for anomalous deformations, integrated into interactive dashboards or delivered via email.
How reliable are the measurements?
InSAR technology can measure displacements as small as 1 mm.
Is post-earthquake or post-rainfall monitoring possible?
Yes. We can conduct rapid analyses after seismic events, extreme rainfall, or excavation works to assess impacts, identify vulnerable areas, and prioritize inspections.
