The problem is that Lightroom replaces a lot of the actually important XMP tags with whatever it puts in there.
Do you still have the raw images as they were recorded by the camera or did Lightroom mangle them? Maybe check your SD card?
For a Flat Map you would need an image taken at the takeoff location so if you didn't use real mapping software you likely don't have that unless you were lucky and snapped a couple on the ground.
