I recently took a bunch of pictures around a location, expecting that each picture's precise location would be recorded so I could place them on a map. This has worked before.
What I found when I got home is that all the photos seemed to have the same location (which was slightly southeast of any location I photographed).
I'm wondering if the iPhone camera is now either rounding off geographic coordinates to a lower precision, or giving all photos taken around the same place and same time the same coordinates, or both, and if so, if this is particular to the Camera app or universal to all apps using the camera.
Extra info
This is on an iPhone 6s running 11.2.1. When I've done this before, it would have been on an iPhone 5 running whatever version of iOS would have been current circa January 2016.
