Elevations change after PPK Stop 'n Go corrections

Hi @petehernandez

If I understand correctly, you compared your elevation from the Reach using stop-and-go with the OPUS result and saw discrepancies in the elevation. Do you still have the issue with elevation? Do you correct your base with an accurate position when processing in Emlid Studio?

How do I convert Ellipsoidal height to Orthometric after the fact?

Even though PIX4Dmatic picks up the “ellipsoidal height” column in the .csv, I don’t think it converts it (automatically, anyways). The .csv out of Emlid Flow 360 starts out with orthmetric feet and I like to keep it that way once the coordinates are corrected so I can see the changes. Pix4Dmatic saw the ellipsoidal height as feet, not meters and threw off the model elevation inspite of labeling that column “Ellipsoidal Height”. I had to manually take the corrected ellipsoidal height and subtra…

Could you share more about the Pix4DMatic workflow? Did you compare it with point processing here?
