Hi.

Is there anyone in the UK who has managed to get their models to output in OSGB36 with elevations in ODN without resorting to inputting GCPs?

My understanding prior to purchase was you could survey without them, especially when tied to the rover unit,  however, I am hitting my head against a brick wall trying to get an output that fits UK standard Eastings, Northings and Elevation.

Pix4D will give you E,N in OSGB, but the Z stays in WGS84...very frustrating when you are trying to produce a survey.

Anyone else struggling, or even better, anyone got a solution?

Cheers

I'm having a similar issue using Terra. I collected LiDAR data with the L1 and want it to output in British National Grid with ODN height, however i'm only getting EPSG 27700 which doesn't include ODN! I'm also not convinced its in WGS84 height either, but its definitely not ODN!

@k4UAV you need to put the ODN height (difference b/w HAE and your vertical datum) in the output coordinate system settings in Pix4D under Advanced>"Geoid Height Above the Ellipsoid"
See https://support.pix4d.com/hc/en- ... -ellipsoidal-height for more info.


ETA- Just realized I replied to a 2 1/2 year old question. Derp!
