Location QR code generator
geo:,
Uses the `geo:` URI, which opens in whatever maps app the phone has set as default rather than forcing one particular service.
How to make a location qr code
That neutrality is the reason to prefer geo: over a Google Maps link: an Apple Maps user scanning a maps.google.com URL gets sent to a browser or an app they may not want. The geo: scheme is handled by Apple Maps, Google Maps, OsmAnd and most others. Coordinates must be decimal degrees with a dot: 52.3676, not 52°22′03″N, and the sign carries the hemisphere, negative for south and west. Six decimal places is about 11 cm of precision, which is more than any consumer GPS delivers, so four or five is plenty.
Questions
Whichever is the phone’s default. That is the advantage of geo: over a service-specific link.
Decimal degrees with a dot, and a minus for south or west. Not degrees-minutes-seconds.
Four or five. Six is about 11 cm, which is finer than consumer GPS resolves anyway.
No. The data is encoded in the pattern itself, so there is no redirect to go down and no account to lapse. A printed code works for as long as the paper lasts.
The plain geo: scheme has no label field that phones honour consistently. The coordinates alone are the reliable part.
