Terrapulse, a live atlas of public signals

Field notes

Terrapulse organizes many different public-data feeds as selectable layers on a single globe, then routes visitors into focused views such as QuakeGlobe, FireWatch and OrbitLive. The homepage exposes concrete readings rather than only category labels: an AQI value for Wellington, a river-gauge measurement from New York, a satellite altitude and a named military aircraft observation. Several sections identify their operating basis, including NASA detections, NOAA forecasts, national water services and community reports.
