GeoWatch is a production-ready, open-source platform for discovering, analyzing, and monitoring critical infrastructure worldwide using OpenStreetMap data.

Search 200+ infrastructure types across 30+ categories — power plants, telecom towers, airports, military bases, hospitals, data centers, and more — with a powerful NLP-driven query engine and real-time map visualization.

Built for analysts. Powered by open data. Free forever.

How It Works

Type a natural language query like "airports near london" or "power plants in texas" and GeoWatch resolves your location via Nominatim, fires a structured query at the Overpass API, and renders clustered results on an interactive Leaflet map — typically in under 1.5 seconds. Results are cached in-memory for fast repeated lookups.
