SurveyingPedia aggregates open geographic and geodetic data from public sources. This page lists every source, its license, required attribution, and commercial terms. We publish this information for full transparency and regulatory compliance.
Summary: All aggregated data is free for commercial use with proper attribution. Raw database redistribution is subject to OSM ODbL share-alike and GeoNames CC-BY attribution. Map tiles from third-party providers have their own commercial terms — consult each provider below.
OSM tile server is operated by a non-profit. For high-volume commercial traffic we will migrate to self-hosted tiles or a commercial provider (Mapbox / MapTiler).
Single user, max 1 req/sec. For heavy use a commercial geocoder (Photon, MapTiler, Mapbox) must be used.
Your rights when using our data
Reading any page, viewing maps, browsing benchmarks: always free, no registration needed.
Personal & educational use: fully permitted without any restriction.
Commercial use of aggregated data displayed on the site: permitted, provided you comply with the licenses of the underlying sources (OSM ODbL + share-alike, GeoNames CC-BY attribution, etc.).
Bulk database redistribution: allowed if you retain ODbL share-alike on the OSM-derived portion and GeoNames attribution. Contact us if you need a commercial-friendly derivative dataset.
Professional/legal reliance: data is provided "as-is". Always verify against the original agency datasheet before using for cadastral, legal, or safety-critical applications.
Accuracy disclaimer
Coordinate accuracy varies by source. NGS and EUREF/IGS stations are typically centimeter-grade. OpenStreetMap survey points are typically metre-grade. GeoNames topographic landmarks (peaks, hills, mountains) are typically 50–500 metres and should be considered reference points, not precision benchmarks. Always consult the linked original source before any professional use.
