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:
-

Tip: The Tag Detection feature can be activated post-capture through the Optimize Autotags workflow. The subsequent processing steps remain unchanged.

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

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

7. Tap Create and the system The system will generate and display a point list containing the coordinate information for each detected point. To review the geographical location of these points, tap the map icon
.

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


9. Utilize the AR Points feature for an augmented reality visual verification of the calculated point locations to ensure positional accuracy.
