Import Ground Control Points window in PIX4Dmapper

It contains the following sections:

  • Coordinates Order: Allows the user to select the order of the coordinates of the file to be imported. Depending the coordinate system, there are the following possibilities: 
    • Latitude, Longitude, Altitude or Longitude, Latitude, Altitude (only if a geographic coordinate system is selected).
    • X, Y, Z, or Y, X, Z. 
  • File: Displays the name of the selected file to be imported.

And the action buttons:

  • Browse...: Opens the Select GCPs File, a navigation window used to search for and select the file to be imported.

Browse a GCP .csv file in Windows to import GCP

  • OK: Imports the selected file.
  • Cancel: Does not save the changes and exits the pop-up.
  • Help: Opens the Pix4Dmapper help.

    I have a question regarding a file I'm processing. 

    My GCP's  are in UTM-17 NAD83 CSRS2010 CGVD28:78.

    The nearest I could find in processing are - NAD83/UTM zone 17N (EGM 96)


    Once I enter in all my gcp's in the GCP manager and start processing, I received  the following error:


    Can you please shed some light? Thanks!

    The GCPs and image geolocation do not lie in the same area. The coordinate systems and/or the GCPs coordinates might not be correct. Do you want to continue processing?

    Can you import the GCPs again and select y, x, z instead of x, y, z? It might be the lat, long is reversed.

    Ah yes that remedied the problem!
