EXIF Embedded Geolocation Data
QUESTION: What source or sources do iPhones use to determine geolocation data, which is then embedded in photographs taken by iPhones?
Is Geolocation data being pulled from Cell Towers, WiFi netorks, a combination of both?
Within an HEIC image file, OSForensics was able to extract the following EXIF metadata:
GPS Latitude Ref: North

GPS Longitude Ref: West
GPS Longitude: 87 deg 44' 55.39"
GPS Altitude Ref: Above Sea Level
GPS Altitude: 183.4873431 m
GPS Speed Ref: km/h
GPS Speed: 0
GPS Img Direction Ref: True North

GPS Destination Bearing Ref: Ture North
GPS Destination Bearing: 178.0244216
GPS Horizontal Positioning Error: 4.648481958 m

How your device uses Location Services
This was a really interesting webinar around location data. May be of some use.
I certainly learned a lot from this one.
