I was recently collecting some test data with a Zenmuse P1 and the resulting orthomosaics were completely scrambled. I'm curious if anyone can provide insight into what might have happened so I can avoid running into this problem on an actual job.
I've attached a screenshot of the satellite base layer for reference, and the resulting orthomosaic after processing. The individual images themselves appeared to be fine. The following setup/settings were used:

- Equipment: M300 + P1
- Mission type: Mapping
- Altitude: 35m
- Side Overlap: 70%
- Front Overlap: 80%
- Image Format: RAW + JPG
- Time Interval shots
- Software: ESRI Drone2Map (reskinned Pix4D)

I flew a total of 4 missions, 3 of the 4 successfully processed but resulted in a scrambled ortho, and 1 failed due to "innaccurate geographic data" or something along those lines. I noticed during flight, the shutter sound from the remote seemed to be triggering at inconsistant times. You'll notice this was actually the case in the screenshots as the spacing between the blue dots is fairly inconsistent.

This is the first time I had tried RAW+JPG mode and one hunch I had was that there was just too much data being saved at once for the SD card or hardware to keep up, although the SD card is reasonably high quality (Lexar Professional 1667x).

Any thoughts on what might have happened and how it could be avoided in the future?

YES! Same. I came here first to see if its a firmware issue or something. My last 2 maps have been messed up like this. We were using the RTK base station both times. Did you?

I am thinking its the RAW+JPG thing. I will turn off RAW and see if it captures correctly.

Hello! I did over 200Ha on latest firmware no weird issue...I had one SD issue but replaced the card and it works as expected.

RTK via national NTRIP network, no DRTK used.

Using same Lexar SD as yours.

Switch to JPG's as you have already worked out its because you are saving RAW and JPG for the photos onto a slow card.
