You should import the pointcloud in a CAD-software.
See printscreen of al the pointclouds from that area (februari 2020-augustus2021) and the position is 100% the same.
See attachment for a printscreen from the pointcloud and the ortho tiles =
I dubbelchecked this error with drone data that came directly out Pix4D Mapper (data from feb 2020) (…site/61412/dataset/627756/model)
Here you can see that the coördinats of the 3D are very far of the coördinates of the 2D, the coördinates of the 2D viewer are the right ones.
See below the coördinates of the 2D =
here the coördinates of the 3D =
at that time we didn’t saw the difference because the difference was exceptional high, with the latest data (from the citymapper) the error between ortho and pointcloud is smaller and we see the 2 annotations in the same viewer (in 2D we see the annotations we made in 3D, and vice versa)
So, I think that pix4d cloud doesn’t import the las file correctly because the problem occures with data from pix4d mapper and 3th party software…
