AI Analysis

●MidEye CandyRabbit Hole

Polished geospatial dashboard, but FlightRadar24, Windy, and USGS already do each layer better.

Strengths
  • •Clean multi-API aggregation with independent error handling prevents single-point failures.
  • •OSM geometry interpolation for realistic vehicle motion across the map.
  • •Thoughtful UX: geolocated first-visit, map state persistence, layer toggles.
Weaknesses
  • •Competes against dominant, specialized tools (FlightRadar24, Windy, USGS) in each vertical.
  • •No novel data source or insight; primarily a skillful integration of existing free APIs.

Post Description

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.
