Read geotagging data from iphone photos exif data
If you are looking for an EXIF viewer on your Mac (which may show the location on a map or the actual GPS coordinates), I would suggest Image Exif Editor. If you look at the screenshots for this app, it clearly shows the GPS coordinates. If you are looking for something similar for your iPhone or iPad, I would recommend doing a search in the App Store using the search criteria "EXIF."
