Output
Area of Coverage: 1500 square kms per satellite image @3m resolution
Data Density: Data points every 9 square meters
Precision / Detection Limit: 2 millimeters
Measurement Frequency: Every 4 – 11 days
On-site Requirements: None; remote sensing, no hardware required
Why InSAR?
- Remote monitoring – no ground instruments or on-site visits required
- Large area coverage – monitor areas up to 1500km2
- mm – cm precision = detect 1-2 mm of displacement per year
- Detecting displacements in areas of known and unknown risk
- Track millions of data points over monitoring area
- Updated displacement measurements every 2 to 12 days

Applications for InSAR
- Detect areas of risk to prevent pipeline rupture
- Ensure stability of all types of infrastructure
- Monitor for slope movement along transportation corridors
- Make better decisions by understanding ground movement threats to existing and planned infrastructure
- Shifting infrastructure due to melting permafrost
3vG Ongoing Monitoring
VFAS Nordic offers the 3vG Ongoing Monitoring Program
- designed to provide clients with actionable intelligence that allows them to mitigate risk
- monitor vital assets such as tailings, dams, pipeline right of ways, and bridges, as well as critical slopes for creep and landslide detection
- custom toolbar for various software platforms to assist clients in efficiently visualizing displacement information
- on-site training for our clients. This training focuses on the operational usage of our products, as well as InSAR fundamentals, benefits, limitations, operational considerations, and comparisons to ground truth data.
- Technical support is provided throughout the duration of a monitoring contract, available 365 days a year.
