Are the GPS coordinates registered by the camera wrong, or is Fotos showing a wrong name for the location?
Have you checked the longitude and latitude of the photos you have taken? Are you using a Mac or an iPhone?
On an iPhone you can see the GPS coordinates, when you open a photo and swipe up to see the details below it, then tap the name of the location above the Map.
- If the GPS coordinates are wrong, a Wi-Fi router in your neighborhood may be broadcasting a wrong location. Sometimes the routers on ships are sharing a wrong location. You can test this by turning off Wi-Fi on your iPhone while taking photos. Then the location services will no longer use the positions derived from Wi-Fi routers. I had this problem when making a cruise on the Danube (in Europe) and a ship following us interfered with the location services. My iPhone tagged all photos with Kansas, on the other side of the Atlantic ocean. After turning off the Wi-Fi on my iPhone I was back in Europe.
- If the GPS coordinates are correct, but the location name is wrong, Apple has to fix the entry in the location database. Then contact Apple again.
