The question then is why Pix4Dmaper can’t read the 3DR log files? The flight log is not edited in any way by me.
Editing the flight log rows as u described can’t be the right procedure - what else is the point of having the option to load a 3DR flight log then when i can’t use the same?
If i follow your description, it practically results in a different input format. I am aware of the different types of Image geolocation files that can be used (PPK image geolocation accuracy). And since when can’t Pix4Dmapper read a latitude/longitude? It shows it in the drop down menu (look at the screenshot).
Or have I misunderstood you? What am i missing?
