Norrvue screens wide areas of high-latitude infrastructure for ground deformation using spaceborne radar and permafrost-aware processing — surfacing where to look before failure forces the question. A detection-and-prioritization layer, honest about its resolution limits, feeding the engineering and intelligence assessment that comes next.
Thawing permafrost destabilizes the ground beneath pipelines, pads, roads, airstrips, and port works across the Arctic. Today the pattern is reactive: movement is noticed once it has already deformed a structure, and remediation arrives as a multi-million-dollar emergency rather than a scheduled inspection. The failure is rarely a lack of engineering — it's a lack of knowing where to point it across thousands of square kilometers.
Interferometric radar (InSAR) measures millimeter-scale ground movement over entire corridors from orbit — no sensors on the ground, no site visit. Norrvue turns that into a validated, permafrost-aware screening layer: a ranked picture of where the ground is moving and how fast, so limited engineering attention lands on the spans that have earned it. Detection and prioritization — not a verdict.
Before making a claim, I built the thing and tested it where the answer is already known. Two sites: an operational infrastructure corridor, and an independent scientific benchmark with published field measurements. The point of the exercise was not a clean story — it was to find where the method holds and where it breaks.
This is a screening capability, not a diagnosis. It tells you where the ground is moving and roughly how fast, at wide-area resolution — enough to prioritize, not enough to replace a geotechnical assessment or an engineering judgment on any single asset.
It is not predictive, and it does not issue a risk verdict. Where the two radar geometries disagree on how a signal is evolving, that disagreement is reported rather than smoothed away — the honest edge of a screening tool is itself the argument for the assessment that follows it.
The full analysis walks through the method, both sites, the validation, and the resolution limits in detail — written for a mixed reader, with the technical appendix intact. If you own, insure, engineer, or assess Arctic infrastructure, I'll send it over. Tell me a little about what you're working on and where to send it.
Goes straight to me. No list, no automation — you'll get a reply, not a funnel.
