updating GCP/marker coordinates?

[wyowill]

What's the best way to update coordinate values for markers/referencing?

Initially, I processed a ground-controlled model all the way through to orthomosaic using what turned-out to be preliminary coordinate values.

Subsequently, I was able to recover GCP data I'd thought was lost to a device failure and able to generate more precise coordinate values.

Using the same source images, I'd like to generate a model with updated coordinates but am not keen to re-digitise marker projections (N > 40 markers each with > 10 projections) nor individually copy/paste XYZ values. 

I'd appreciate any recommendations for:

1) updating in bulk (e.g. importing new values to existing markers), and/or
2) need to reset camera alignments[/li][/list]

Cheers

Hello wyowill,

You can import the coordinates of the marker location from the text file, which contains the following columns: marker label (as it appears in the project), X-coord, Y-coord and Z-coord. If you have such file, just click on Import button on the Reference pane toolbar and adjust the proper column order in the Import CSV dialog.
Make sure that the proper coordinate system is selected.

The coordinates for the markers with the found labels will be substituted by the values from the file.

After the import press Update button on the Reference pane toolbar to apply the new coordinate information. If necessary, you can also optimize the camera alignment.
