Geographic Coordinate Generator

Generate N random lat/long pairs — approx. uniform on a sphere — with optional OSM map links.

Options

Generate N random latitude/longitude pairs (approx. uniform on a sphere: latitude via arcsin). Optional OSM map links.

Uses your browser’s Web Crypto CSPRNG (crypto.getRandomValues) — strong PRNG for games, picks, and development. Not atmospheric true-random like RANDOM.ORG.

FAQ

Is this the same as RANDOM.ORG?

No. This page uses your browser’s Web Crypto CSPRNG, not atmospheric noise.

How is latitude chosen?

We sample u∼Uniform(0,1) and set lat = arcsin(2u−1) so points are roughly uniform on a sphere.
