When a GPS-device has been switched off, moved to another location and switched on it needs some minutes to fix all "visible" sattelites and reach a good precision. When a GPS-devices has not been switched on for a longer time, it needs to "download" some long term data (almanache) from the sattelites. This may take some time. https://de.wikipedia.org/wiki/Almanach_%28GNSS%29 en ? Frank darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org

Re: [darktable-user] Geo Location Question
This is probably unrelated to David's issue, but I have noticed in the last few Darktable versions (up to 3.2.1) that images as rendered on the map are mislocated by a /consistent/ amount no matter what map source is used -- ranging from a few hundred feet when the map is zoomed in as far as it will go, to about 1,000 miles when fully zoomed out. Has anyone else noticed this? -- August Schwerdfeger aug...@schwerdfeger.name On 1/28/21 9:32 PM, Patrick Shanahan wrote: > * David Vincent-Jones [01-28-21 21:18]: >> I am now using a camera/phone that provides lat/lon image data.
