See the ground move, millimetre by millimetre.
GeoFringe turns Sentinel-1 satellite radar into point-by-point ground-motion measurements: how fast buildings, roads, pipelines and levees are sinking or rising, with an uncertainty on every number, for engineering, infrastructure and insurance teams.

What you get
A measurement product, not a pretty map: every point carries its velocity, its uncertainty and a time series you can check against your own surveys.
Per-point velocities
Line-of-sight motion in millimetres per year for buildings, infrastructure and open ground, with a one-sigma uncertainty on each point.
Full history
Displacement time series from 2019 onwards, so you can see when movement started, whether it is accelerating and how it follows the seasons.
Validated against GNSS
Results are tied to and checked against permanent GNSS stations, and each delivery ships with a quality report that shows its own error statistics.
Where it helps
Infrastructure owners
Screen pipelines, roads, rail, levees and utilities for subsidence before it becomes a repair bill.
Engineering and construction
Baseline a site before works, and watch dewatering or tunnelling effects on the buildings around it.
Insurance and real estate
Understand ground-movement exposure across a portfolio with evidence, not assumptions.
How it works
Sentinel-1 satellites image the same place every 6 to 12 days. Tiny phase differences between passes reveal how the ground has moved.

Houston pilot
Our first pilot covers the Houston area, where decades of groundwater withdrawal have made subsidence a measured, regulated issue, and where a dense GNSS network lets us validate every result independently. We are working with a small number of design partners. Get in touch if you would like to be one of them.
