Show HN: Signet – Autonomous wildfire tracking from satellite and weather data

Autonomous monitoring · Always follow official emergency guidance

How Signet Works

Signet turns satellite detections, thermal imagery, and weather data into autonomous wildfire tracking across the continental US.

Autonomous Orchestration

Continuously triages NASA FIRMS detections, GOES-19 imagery, and follow-up investigations without waiting for a human to initiate each step.

Each cycle returns both an assessment and the next-cycle decision, while incidents, observations, predictions, and agent decisions are logged separately.

Multimodal Reasoning

Correlates satellite thermal imagery with geographic and environmental data to analyze spatial patterns and temporal evolution.

Uses data from NWS, USGS, LANDFIRE, Census, OpenStreetMap, and grounded web context to evaluate fire behavior, nearby exposure, and likely persistence. Model-driven analysis is used where the problem stops being clean rules: deciding which weak signals are worth another pass, what context to pull next, and how multiple noisy sources combine into a structured assessment.

Technical Architecture

Persists raw FIRMS detections, interpreted GOES observations, weather inputs, predictions, and official cross-checks in structured tables.

Assessments, tool calls, incident updates, and prediction outcomes stay visible in the live feed instead of being hidden behind one final answer.

Signet is not a substitute for official emergency information. Do not use this system to make evacuation, safety, or emergency response decisions.

For official wildfire information, refer to NIFC, InciWeb, and your local emergency management agency.

AI-generated assessments may contain errors. Satellite data may be delayed or incomplete. Official cross-checking currently relies on the NIFC IMSR current incident feed, which may miss smaller or emerging incidents. All analysis is provided as-is with no warranty.

Wildfire Alerts

Signet monitors satellite heat detections for fire activity near your area.
