fantastic! thanks for the reply.

It is now possible in "Update 15"

this is precisely what i'm running into. Contextcapture need to find a way to use GCP and RTK selectively and work together

Yes I do understand that Camera calibration is essential but I was asking if it is possible to run aerotriangulation with RTK and GCPs together? For e.g. I have one GCP for height and rest of polygon will rely on RTK picture pose, is it possible? Maybe there is a sequence of creating aerotriangulation first on RTK and run it second time with that one GCP?

You can check on any project. The camera calibration before and after adding GCPs are the same even for models which were curved before. The warping on GCPs seems to be additional parameter.

I didn't get it. Would be nice to test on some project if it even works wth RTK. Do you know if somebody confirmed that?

Problem is that if using GCPs then RTK is not used. So if not reusing good calibration it tries to warp the model as-is on GCPs. It seems GCP are not used for camera calibration.

What do you mean Oto? CC is not built to use rigid EXIFes or ?

Ah, many thanks Oto, I thought that with the new update and because the camera model was added that it was fixed. But then I know what to do. Thank you.

As of CC U14 it is not using RTK positions correctly yet you have to reuse calibration.
