Advanced Processing



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.
