InSAR monitoring of urban areas provides value across a number of sectors including natural gas utilities, engineering construction projects, and transportation infrastructure:
- Identifying localized areas of displacement across an entire city for gas distribution networks can help utilities prioritize maintenance locations and prevent potential failures.
- Millimeter-scale, remote monitoring of subsidence during underground tunneling projects provides tens of thousands of data points in and around the project location without needing to close lanes of traffic nor obtain approval from building owners for survey markers.
- Urban InSAR monitoring also provides regular measurement data to assist in infrastructure asset management of critical transportation structures such as bridges, overpasses, retaining walls, and highway networks. 3vG can also track expansion and contraction of steel structures from ambient temperature changes to isolate irregular displacement trends.
