Transitioning from a Phantom 3 Pro to a Phantom 4 Pro and the first mission run on DroneDeploy the bird ran in reverse. This begs the question were the photos assumed upside down (front side back)? Images looked great and everything else about the mission was flawless. Followup on this issue was the fact that tagging GCP's was unsuccessful. When tagging the initial point the images that the system selected for the additional GCP's were all over the site.
First run today, 01/29/2018.
