When Infrastructure Fails, People Are Waiting. Know Who Needs You First.
TriNetra combines satellite imagery analysis, infrastructure dependency mapping, and real-time cascade modeling to help emergency teams make faster decisions in the critical first 72 hours.
The Three Eyes
Damage classified in under 90 seconds.
Cascade calculated in under 400ms.
Restoration ranked before teams mobilize.
The problem
When Maria made landfall, 95% of Puerto Rico lost power.
Hospitals had 72 hours of generator fuel. Utility crews had no map of what depended on what.
TriNetra was built so the next response team doesn’t fly blind.
TriNetra: The Three Eyes
Three layers of intelligence. One decision surface.
Eye 1: Damage Detection
See What Broke, The Moment Imagery Arrives
The pipeline pulls pre- and post-event RGB stacks from Microsoft Planetary Computer (NAIP with Sentinel-2 L2A fallback), crops per asset, and runs a six-channel EfficientNet-B4 classifier in PyTorch. CUDA accelerates inference when a GPU is present; otherwise the model runs on CPU.
Eye 2: The Dependency Graph
One Substation Goes Down. Find Out What Goes With It.
Behind every city is an invisible web: power flows to water treatment, which flows to hospitals, which flow to the people who need them most. TriNetra maps 14 types of infrastructure dependency so when something breaks, you instantly see everything it takes with it.
Eye 3: Priority Scoring
Not a Map Full of Red Dots. A List That Tells You What to Do.
After a damage observation runs through the cascade engine, its priority score scales the log of total downstream population impacted by the strictest affected criticality tier, model confidence, damage severity, and an urgency term tied to how soon the first downstream asset hits time-to-failure, so restoration order reflects real failure horizons, not dot density.
