Is there any online tool where I can upload a photo that doesn't contain GPS data in the EXIF metadata, but gives me an estimate of the location that the photo was taken from - e.g. not just identifying the Eiffel Tower but also whereabouts I was standing when I took it. I'd love to be able to enrich my older photos with reasonably accurate GPS location - or at least a '95% chance that the photo was taken within 500m of this point'.
there is this: https://twitter.com/whereml. Another option is to use something like GPT which might have sufficient understanding of some of the objects... But I think unless you have some very memorable objects like eiffel tower or big ben it will be very rough.. E.g. a picture of a beach will be impossible yet this system might put it somewhere... So I would be a bit worried about trying to automate it..
