InSAR
GVL delivers expert InSAR data analysis for high-precision ground movement monitoring. Leveraging advanced satellite radar technology, we provide accurate, all-weather insights to support infrastructure development, mining operations, urban planning, and environmental management.

At GVL, we offer advanced AT-InSAR (Advanced Interferometric Synthetic Aperture Radar) services to detect and monitor ground movement with millimetre precision. By analysing satellite radar data over time, we generate high-resolution 3D terrain models and time-series outputs that reveal subtle surface changes across wide areas. With rapid turnaround and expert processing, our AT-InSAR service delivers the accuracy and consistency needed for confident, data-driven decision making.

AT-InSAR is an invaluable tool for monitoring surface deformation across a wide range of environments. From urban centres and infrastructure networks to remote or vegetation-covered regions, it enables continuous, wide-area observation with high spatial detail. The technology is ideal for tracking ground instability, supporting environmental risk assessment, and informing development planning, delivering actionable insights where accuracy and reliability are critical.

Using AT-InSAR, we monitored Mexico City, one of the fastest-sinking cities in the world, by analysing 132 Sentinel-1 satellite images from 2019 to 2021. Our results revealed ground deformation exceeding 300 mm per year in some areas, clearly visualised through 3D models and time-series data. This case demonstrates the power of AT-InSAR to uncover critical land movement patterns and support proactive urban risk management.

GVL delivers flexible AT-InSAR services tailored to your monitoring goals. Whether you need broad-area surveillance or focused analysis of specific sites, we adapt our processing approach to suit your requirements, including use of Corner Reflectors for increased precision and reliability at critical locations. Our solutions support both one-off assessments and ongoing monitoring campaigns, offering scalable, reliable insights backed by technical expertise and advanced data interpretation.
