For instance, when checking some images I can see that there’s a ton of EXIF information in there, including the precise location where the image was taken:
✔ ~/blog $ exiftool ./2019/11/IMG_20191111_2029432-825x510.jpg ExifTool Version Number : 11.76 [...] GPS Version ID : 188.8.131.52 GPS Latitude Ref : North GPS Longitude Ref : East GPS Altitude Ref : Above Sea Level GPS Time Stamp : 19:29:43 GPS Dilution Of Precision : 16.132 GPS Img Direction Ref : Magnetic North GPS Img Direction : 178 GPS Processing Method : fused GPS Date Stamp : 2019:11:11 [...] GPS Altitude : AA.A m Above Sea Level GPS Date/Time : 2019:11:11 19:29:43Z GPS Latitude : DD deg MM' SS.SS" N GPS Longitude : DD deg MM' SS.SS" E
