Hello Kiteman,

could you post a copy of your XYZ txt file?  Seems to me that your reference CS is set to local and not WGS84....

Hello Stefano,

Can you please also share full-resolution screenshots of the Reference pane settings dialog before loading the coordinates from the file and a screenshot of Import CSV dialog with the parameters used?

It seems to me that on the screenshot from your first post Local Coordinates system is assigned to the chunk, including cameras and markers. So you probably need to switch the coordinate system to WGS84 both for cameras and markers before loading GCP coordinates.

Hello kiteman,

to see marker errors, you must pin them in each foto ( or at least 2) where they appear...
