I am still looking for any viable explanation for the wild error in the elevation map created in Maps Made Easy from the images from one of my P3As. today, I flew all 3 using the same mission. Each aircraft has a dedicated controller, but I use the same iPad on all of them. Each is running the same versions of firmware. For 2 of the maps, the processed heights were within less than a foot of the height that I directly measured. On the third, the same heights were only 55-58% of the true height (reported average height AGL was off by the same percentage). Every inspection that I have done of the exif data shows that all are recording the same info and doing it correctly. If anyone has any ideas, I would much appreciate hearing form you.
