Hi @mikariekki5708, I believe that WebODM will always use the closest UTM CRS to georeference a dataset, and the GCP file is also internally projected to UTM during computation. See community.opendronemap.org/t/coordinate-reference-system-and-gcp/4486
@@jeremymaurer9554 Thx, didn't know what proj string etc meant and EPSG: 3879 didn't work. Found out later that I could get the correct coordinate definition in the old string format from ie. QGIS, and that worked. I wish the plugin would filter relevant photos by gps. Only used WebODM and GCP's in one mapping mission so far now. Before that I used Recap Photo for other projects where a surveyor took the GCP's. That was a more streamlined experience, but but both need the coordinates given in a precisely correct format. Ie. Recap Photo doesn't accept commas and uses points since its US based, and WebODM the other way around, also need to flip the X and Y coordinates for both programs. And WebODM doesn't accept tabs, but uses space instead. :/
how did you get the xyz of those GCPs? thank you! great video!
Could you provide us with the Images, so we can try it as well, since we do not have drones, it is difficult for us to do the hands-on.
Is it possible to use projected coordinates at all?
