How to get coordinates from Autotags? 

In PIX4Dcatch, the Autotag feature provides a fast and precise way to extract coordinates from automatically detected tie points. This workflow enables accurate measurement of multiple points within a project with minimal manual effort.

To successfully obtain these coordinates, follow the next steps:

  1. Display the Autotags at each of the critical points requiring measurement.

         

        2. Activate the Tag Detection Feature. 

            Access the capture menu, select the dots menu icontools menu and then tap the tag detection icon             autotag icon.Enable the detect autotags slider.

       5. Open the saved project and tap on the icon and select Create Point Collection from Tie               Points

           menu create point collection from tie points

         6. Insert a mandatory name for the collection and select the required output Coordinate                          Reference System.

           8. To extract the created coordinate data, tap the export icon and select the desired                          export method for the .zip file.
