a sudden increase in error (with GCP)

Hi,there!

I followed the usual procedure & setting for 3D Map,

but there is a sudden increase in error (with GCP).

For comparison, I attach a log file with a small error(good one) and a log file with a large error(bad one).

Can anyone tell me why the error has increased?

Hi @gunsec, We would need the quality report of both the projects. The GCP error also depends on how accurately you mark the GCPs. Make sure you are processing the correct workflow for adding GCPs.
