I was trying (unsuccessfully) to explain that Geolocation API does not provide the information you want, but you might have significantly different values for accuracy, whether you have a GPS location or not.

If you go native programming, then you might have other possibilities. /Mogens On February 4, 2022 at 12:31:31 pm +01:00, Rune Back <rune.b...@gmail.com> wrote: > Yes, of course, but that's not the issue. - As a programmer of a site or an > APP, you can (with the surfer's permisssion) get the GEO location of the > surfer using the information of his/her browser.
