Layers in your GIS
OGC API Features and Esri FeatureServer 11.1 query, plus GeoJSON and CSV exports of assets and displacement.
Built to hold up.
Know where the ground is moving under your pipelines and power lines.
GroundPulse reads every mile of your network from orbit every 6 to 12 days with Sentinel-1 and NISAR radar, ties the movement to your routes, and hands your crews one ranked list of where to look first. Nothing gets installed in the field.

What you get
One ranked list of where to look first.
Radar satellites re-measure each ~30 m cell of ground on every pass, in any weather. We tie that movement to the routes and assets you already maintain, so field, ILI, and geotechnical budget goes where the ground is moving.
Pipelines
Per-segment displacement rates, ranked segments, and screening reports along the route. Where neighboring segments move at different rates, the along-route gradient flags where pipe may be stretching or bending, and a per-station strain profile feeds your integrity program.
Pole lines
Distribution and transmission lines are screened along their route, so you see which stretches of line stand on moving ground, from slope creep to subsidence. Your pole inventory ties a flagged stretch to the specific poles.
Bridges
National Bridge Inventory import, per-bridge screening, and movement history, with asset context and displacement in the same view.
Roadways
Roadway, segment, and district views with movement observations and exports.
How often
A new reading every 6 to 12 days.
GroundPulse picks up each new Sentinel-1 scene and processes it scene by scene. Every pass updates the movement rate on every segment and stretch of line, re-scores its trust, and re-checks your alert thresholds. A new route starts from the satellite archive, so your first report already carries months of history.
Sentinel-1 · C-band
ESA’s Sentinel-1C and 1D restored a 6-day repeat in June 2026, with a new pass every 6 to 12 days depending on location. Fine sensitivity on open, urban, and engineered ground.
NISAR · L-band
NASA and ISRO’s NISAR passes every 12 days. Its 24 cm wavelength holds signal through vegetation and crops, so wooded and farmed rights-of-way get their own movement record. GroundPulse processes NISAR into displacement through the same pipeline as Sentinel-1.
How it works
From orbit to a work list.
1
Satellites measure
Sentinel-1 and NISAR re-measure the distance to every cell of ground with radar phase on each pass. Comparing passes yields a movement-rate map, and ascending and descending passes separate vertical from east–west motion.
2
GroundPulse ties it to your assets
Movement is attributed to each segment, stretch of line, and structure. Every reading carries a 0–100 trust score, and severity and trust together set the action.
3
Your crews get a work list
Composite risk blends movement, worsening, and consequence into one ranked list, with PDF and HTML reports for operations and executives from the same data.
Integration
Works inside the systems you already run.
Your GIS, integrity, and work-management tools read GroundPulse through the standards they already use. Integration is an API key and a layer URL.
Maps and rasters
WMTS and XYZ tiles, PMTiles, and Cloud Optimized GeoTIFFs for your own analysis.
Alerts in your work queue
Webhook push on every threshold breach, and an alert API to acknowledge, assign, snooze, and close.
Reports and a spec to build against
PDF and HTML reports on demand, a per-station pipeline strain-profile endpoint, and an OpenAPI 3 spec. Scoped read-only API keys, revocable at any time; pipeline route data is encrypted and hosted in the US.
Measured performance
Checked against NASA and against the ground.
Pipeline corridor
Permian Basin crude line
429 monitored segments from Midland to Monahans/Wink, per-segment rates from −17.9 to +6.8 mm/yr, mean coherence 0.92 over 12.3 million coherent samples. Consistent with the subsidence documented by Staniewicz et al. 2020 in GRL.
Engine
Matches NASA’s OPERA product
Our processing engine reproduces NASA’s OPERA DISP-S1 displacement product at a correlation of 0.998 on identical acquisitions.
Ground truth
Agrees with GNSS stations
Median velocity difference against survey-grade GNSS stations is 4.05 mm/yr, inside OPERA’s own 5 mm/yr requirement. Per-pass precision is about 9 mm RMSE vertical against GPS.
Who it is for
Built for the people who own the assets.
Pipeline operators
Integrity, geohazard, and right-of-way teams at gas, oil, and NGL operators who need coverage between patrols and Level-1 geohazard screening in the API RP 1187 sense.
Electric utilities
Transmission and distribution engineering, asset reliability, and line-clearance teams who need to know which stretches of line stand on moving ground.
State DOTs
Bridge, roadway, and geotechnical teams prioritizing field review between inspection cycles.
Data sources
Built on open government satellite data
Every result carries its source scenes and processing record.
