Sample vs Experimental continued…. GCPs and MTPs

Samples produced rarely include Ground Control Points. If I do include GCPs, typically it’s 3 max. The drone’s geo-location data while mapping is enough to get the model’s individual photos assembled again in the software- in just about the right order and location. All the samples have Manual Tie Points, MTPs, around 50 and occasionally up to 100, are created. If “Cloud Processed”, then no GCPs or MTPs added. Experimentals are about the same setup with respect to GCPs and MTPs, with the exception of a few models. Lately,I’ve been trying to include Scale Constraints more. Mainly MTPs, around 50, and occasionally around 3 Scale Constraints instead of 3 GCPs.
