Take a photo at each way point, with GPS mode on, you use Exiftool to pull the lat long out of the photo, Civ3D supports lat long input anyway have a look at this.
exiftool -filename -gpslatitude -gpslongitude -T "p:\2018 projects\2018104\photos" > out.txt
The text file contains photo name and decimal Lat long.
I am trying to find code I created it makes points and inserts the photo at the lat long position. I think I used the CIV3D point description as photo name so just re-read the points.
