Shift Horizontally and Vertically in Point cloud

I am processing around 1100 photos from 4 individual flights combined into one project and processed. Initially I processed step 1, added GCP’s everything looked good so I ran steps 2 and 3. After completion I noticed 1 area had a vertical and horizontal shift. I added multiple MTP’s in the basic editor and re-optimized. The shift has not changed in the slightest. I found 1 GCP that also had a varying hirizontal and vertical shift. I omitted that GCP from processing and re-optimized with no change in the shift in the point cloud. The shift is located between two flight lines where it was flown with 65% side overlap. This appears to be the only location on the project that has a shift. Any suggestions as to how to get these two potions to line up is greatly appreciated.

Hi Dustin,

Could you share a quality report with us? This will help a lot in finding the cause of the shift.


Absolutely, I will post it as soon as I can. The program is running now using all computer resources so I can re-generate as soon as it completes.
(has it been discussed to have the ability to “Pause” processing?
