Greeting! uploaded GCPs text file, selected GCPs containing at least 3 imgs for each GCPs, created GCPs file and saved it as gcp_list in folder where the imagery is. then selected images and set processing parameters. after process is completed, I find in quality report that gcp files is not used. Can’t find out the issue why gcp_list file is not being detected though I followed instructions to create and place the file in folder where the imagery is. Anyone guide please.

gcp_list file contents
+proj=utm +zone=42 +ellps=WGS84 +datum=WGS84 +units=m +no_defs

Welcome, Arif!

Are you certain that the file was named gcp_list.txt and not just gcp_list as you indicated above?

https://docs.opendronemap.org/gcp/#gcp-file-format

named it gcp_list and not gcp_list.txt. if this is the issue then renaming gcp_list as gcp_list.txt will be Ok or I will have create the file afresh?

You won’t have to re-create the file, but you will need to reprocess the data from “Load data”.

Thanks a lot for your prompt support. Stay Blessed! Warm regards
