I am attempting to find ground control points for historical aerial images. I have a reference Digital Elevation Model (2016), which I have used to georeference multiple flightlines over a mostly glaciated island (1959). While I was georeferencing I created a point shapefile layer of the points that I used. I am wondering if there is a way to pull out the original pixel coordinates of my historical aerial images (before they were warped by the georeferencing process)for each of these ground control points?
I am using QGIS version 3.18.2-Zurich
There is the original points file created in the georeferecing process, however that doesn't include points which I added later and it would be rather time consuming to open one of these files for each image and compare the lat lon, then copy and paste pixel coordinates.
