I was out today to do a multi-layer photogrammetric survey. I used Drone Deploy first to survey the area vertically and the used Pix4D to capture the same area at a 30 degree angle. Since I was out in the field I had no way to review the images from the Drone Deploy session before doing the Pix4D flight. However, Drone Deploy indicates when a photo is taken and I had no doubt the shot were done. When I got home I only found that the Pix4D photos were on the memory card anymore. Either Drone Deploy never took the photos or Pix4D decided write over existing files.
Has anybody had a similar experience?
