Hello,

Does the number of marked images matter? Let’s assume we have 50 images that we can mark belonging to a GCP. Is there any difference in marking 5 or 50 images as long as we reach the accuracy we want with 5 images?

Kind Regards

I would recommend marking between 10-15 images. You can mark more but the most important thing to consider is to only mark the very best images at the highest zoom possible. In addition, I would only mark GCPs that are at the center of the image. When a GCP is near the edge there is more distortion and thus more room for error.
