Coordinate Generator

What it does

The Coordinate Generator produces random latitude/longitude points — up to 10,000 per run — for map testing and geospatial demos. Scatter points worldwide or cluster them within a radius (0.1 to 100 km) around a center, choose the coordinate format, and control decimal precision. Seeded runs regenerate the identical set of points.

Common use cases

• Map UI testing — thousands of markers to exercise clustering, viewport culling, and rendering performance.
• Geospatial demos — plausible point layers for dashboards and presentations without touching real location data.
• Geo-query fixtures — points clustered around a known center to test radius searches and bounding-box queries.
• Load testing — bulk coordinate payloads for location APIs.

Settings

• How many — 1 to 10,000 points, exportable as text, CSV, or JSON.
• Coordinate type — the output format for each point.
• Mode — global scatter, or clustered around a center point.
• Radius (km) — the cluster spread, 0.1 to 100 km.
• Decimal places — 0 to 10; about 5 decimals ≈ meter-level precision, which is plenty for most fixtures.
• Seed — identical seed + settings = identical points.

Privacy note

Points are computed locally in your browser and never uploaded. They are synthetic locations — random math, not real places, people, or devices — so there’s nothing sensitive to leak and nothing real to misread.

FAQ

Do points land uniformly on the globe? Scatter mode draws across the coordinate space; note that naive lat/lon scatter visually concentrates near the poles on some projections — cluster mode is the better choice when realism around a city matters.

Can some points land in the ocean? Yes — coordinates are unconstrained by land. If you need land-bound, city-like data, pair this with the Country and City generator.

How many decimals do I need? Five (~1 m) for realistic markers; two (~1 km) for city-level scatter. More than seven mostly adds noise.
