We are having an issue that happen periodically when we are using an arbitrary coordinate system for GCPs. We go through the initial processing (adding photos, adding GCPs, basic editor) but we get an error saying that our RMS is too high. (see screenshot)
We have only got this error when we use an arbitrary coordinate system and it has only happened on a few of our flights. When we reprocessed the same flight using the same workflow, we did not get this error.
We are curious why the same flight would yield different results and if there are steps to prevent this error from occurring?
