Geo URI Builder

About this calculator

The geo: URI scheme, standardized in RFC 5870, is a compact way to encode a geographic location as a single string: geo:latitude,longitude, with optional altitude and a u= parameter for positional uncertainty in meters. Unlike a link to a specific map provider, a geo: URI is provider-agnostic — the operating system decides which installed mapping app should handle it.

This makes it the standard way to embed a location in a text message, QR code, calendar invite, or contact card so that tapping it opens the user's preferred maps app (Google Maps, Apple Maps, OsmAnd, etc.) directly at those coordinates. Android and iOS both register geo: as an intent/URL scheme, which is why developers and mapping tool builders rely on it for cross-app, cross-platform location sharing instead of hardcoding a specific map service's link format.
