GCP 3d file format?

[littlecloud47]

Hello,

I would like to know the file format for 3d GCPs.
I have tried this :

Hello littlecloud47,

2D Coordinates are in the format (at least two rows for each point)

Point1 PictureApath.jpg X Y
Point1 PictureBpath.jpg X Y

while 3D coordinates are in the format

Point1 X Y Z
Point2 X Y Z
Point3 X Y Z

In your case i assume you are importing 3D coordinates, so you should remove the picture path column. You would have then duplicated rows but that's not a problem since the coordinates are the same, zephyr will just skip the duplicate lines.

Make sure to have a look at this tutorial for some examples
