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 Latitude:  42 deg 0' 15.63"

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 Img Direction:  178.0244216

GPS Destination Bearing Ref:  Ture North

GPS Destination Bearing:  178.0244216

GPS Horizontal Positioning Error:  4.648481958 m

This was a really interesting webinar around location data. May be of some use. 

I certainly learned a lot from this one.
