I have three questions with respect to GCP’s:
Must EVERY image that contains a GCP in the picture be tagged or associated in the GCP Interface processing? For example, if I have 5 overlapping images that show the same GCP, must I map all 5, or does an increased count just increase the averaging and accuracy?
I noticed a “floater” non-associated crosshairs during the GCP Interface mapping process that I didn’t create. Why is this automatically put on both my image and the map? Is this somehow intended to be an automated part of the process?
Is it possible to apply a GCP file to a project retroactively, or must the file be created via GCP interface and uploaded in conjunction with the pictures before the imagery is processed?
