Geotag is an EXIF metadata associated with a single photo that give the geographical location of where the photo has been taken. At this time, the geotag EXIF is fully supported by Photos (we see the location on a map) and we have the option to strip the information when we share the photo. To work with Photos, the EXIF geotagging info must be embedded with the photo when it is transferred from the camera to the Photos App.
However, many cameras don't have a GPS that sets the photo location. The geotag must be added later manually. Some photo editing software strip EXIF data (or just Geotag data) and sometimes these photo editor apps set geotag of their own (the location where the picture is edited, not the original location where the picture comes from).
It would be nice to add a geotag addition/edition feature to Photos.app.
