Attribution
Each widget includes a small "Powered by SurveyingPedia" link in the header. That's the only requirement — no other branding, logos, or watermarks. Free for commercial and educational use.
Performance & loading
Widgets use loading="lazy" in the example HTML so they only load when scrolled into view. Maps initialize client-side with Leaflet and stream data from our cached APIs (5-min cache for earthquakes, nightly for CORS and benchmarks). Server-side rendering is disabled inside the iframe to keep your host page fast.
Data freshness
- Earthquakes: live from USGS FDSN, refreshed every 5 minutes.
- CORS stations: aggregated from IGS, EUREF-EPN, NGS, RGP and regional networks. Updated nightly.
- Benchmarks: NGS + OSM-sourced + community contributions. Updated as new data comes in.
