Importing Control Points for Georeferencing

Markbe_utco — Fri, 03 Jun 2022 21:49:05 GMT

I was georeferencing some an image with the control point table open. ArcGIS Pro siezed up. I took a screenshot of the control point table so I could run and OCR on the image. I parsed the OCR interpretation into a text file hoping I could just import the ground control points. I tried following the format of a known valid exported Control Point files. Unfortunately when I try I get the error message: The input links file is invalid.

I can import other txt files that were created through the Export Control Points button. Here are the first few lines of the txt file. I have tried delimiting with spaces, tabs, and commas.

I'm having an even worse problem. Ground control points that I generated using auto-georeference in ArcGIS Pro and am trying to import back in again won't even work! They did just earlier today, and the file was not edited. Hopefully someone from ESRI seems this and takes note.

UPDATE: I'm guessing the files were somehow locked by ArcGIS Pro. Copying the .txt files via File Explorer and attempting to import the copies worked without issue.

I was having trouble with this error message and opened the control points .txt file in notepad and removed the invisible carriage returns after the last bit of text and that seemed to fix the issue for me.
