Show HN: TerraViz – Real-time flights, earthquakes, ISS on one map

TerraViz – Real-time flights, earthquakes, ISS on one map is a business in show hn launch.

Profile

I built a client-side geospatial dashboard that pulls from free public APIs and renders everything on a single Leaflet map.Data sources: OpenSky (flights), USGS (earthquakes), Open-Meteo (weather), Open Notify (ISS), Overpass/OSM (roads and railways). Vehicle movement is simulated client-side using interpolation along OSM way geometries.Each layer fetches independently with its own error handling so one API being down never breaks the rest. Map state persists to localStorage and first-time visitors get geolocated via ip-api.com.Stack: Vite, React, Leaflet, Tailwind CSS.Would appreciate feedback or suggestions for more data sources to add.

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

The company is listed at the Show HN launch stage of development.
