GCP Editor Pro coordinate system problem

I have been trying to use the GCP Editor Pro and have had no luck with the coordinate systems. If I type the EPSG code I cannot go to the next step. When I use the PRJ4 line, it allows me to go to the next step, but the points are not showing in the right place or orientation. Even tried bringing the points in a different projection; followed the same steps and the points are not in the right place or orientation. Any help will be greatly appreciated. If allowed, I can share the data files with you and give you the EPSG codes to see if it works on your end. I would like to buy the GCP editor, but if it doesn’t work for me, I can justify the purchase.

Who doesn’t love projection problems? :rofl:

I don’t see why you can’t share the data so we can take a poke! It’s up to you if you wish to do so, honestly.

Sure thing. The data is in the following format;
Name, Northing, Easting, Elevation.

Is this strip survey correct?

No, that is exactly what I’m getting. Problem is the survey was in Iowa and the road I surveyed runs W to E.

Bruh, haha.

Can you drop me a pin or something on the midpoint of that section of road so I can troubleshoot this more?

Where did this data come from?

On the surface it looks like the old easting -northing switch. GCP editor likes easting first then northing. The example file above is nothing- easting. I always look for the simple answer first. Sorry if I’m over simplifying

Yep, it seems like a bug in the CSV import. If you swap easting for northing it should work.

We’re going to fix this in the next release.

Thanks for the prompt response Piero… I didn’t even thought about swapping the coordinates, since the template was N,E,Elevation.
Looking forward to give it a shot later tonight or tomorrow.

If you re-download/re-instal the software the easting/northing coordinates should be fixed (version 1.1.0).
