Hi Mario,

The reason why the values are not recognized is that, in order to import the accuracy values using the text file, the omega, phi and kappa angles need to be included in the file. As described in the Input Files article, the following format is expected:

imagename,latitude [decimal degrees],longitude [decimal degrees],altitude [meter],omega [degrees],phi [degrees],kappa [degrees],Accuracy Horz [meter],Accuracy Vert [meter]

The following workarounds can be used:  

a. Changing all the values at once to the same value in the Image Properties Editor. 

  1. Create the project from scratch.
  2. Right click  one cell of the column in the image properties editor.
  3. Click  Edit All Altitudes / Horz. Accuracies / Vert. Accuracies.
  4. Type the new value.
  5. Click Enter or click outside the cell.

b. Editing the .csv file so it also contains the omega, phi, kappa angles:

  1. Create the project from scratch.
  2. Export the image geolocation by using the “To File…” option in the Image Properties Editor.
  3. Edit the exported file/ add the accuracy values at the end of the lines (excel, notepad).
  4. Import the image geolocation file by using the “From File…” option in the Image Properties Editor.

At the moment, it is possible to import and define the Accuracy Horz and Accuracy Vert values, and not also separate values for X and Y. To compute the Accuracy Horz we calculate the average value of the RtkStdLon and RtkStdLat.

In your specific case, the input file would look like this:

Best,
