Pix4dmapper Elevation Error

[himalay.sharma]

Hi Pix4D Community,
I am using pix4dmapper version 4.4.12

1. I first processed the drone data in Pix4DMapper for volume calculation.
   Its quality report with raycloud snap.

2. I knew the mean sea level, so I processed it in (MSL) EGM 84 Geoid in my computer. The elevation obtained in the first processing was the same elevation I got after processing (MSL) EGM 84 Geoid. The elevation did not change.
   Its quality report with Ortho snap.

3. I again did the same process in another computer with (MSL) EGM 84 Geoid but still the elevation did not change.

4. I again did the same process in another computer with (MSL) EGM 84 Geoid but still the elevation did not change.

5. I did the same process again on a laptop and the elevation got changed. I did the same process on three computers, but the elevation did not change, but when I did the same process on the laptop, the elevation changed, despite having the same pix4dmapper and the same version. Why did this problem occur?

Hello @himalay.sharma, For the last project, you are using different processing option that is why you might be getting the difference. Turn on the Geometrically verified matching option or the best way would be copying the .p4d file to your laptop and double click on it to open a project with same processing option that was used on that old project.
