Say I have a GeoTIFF that covers an area of 2000mx1000m. The GeoTIFF is 2000x1000 pixels. It has been exported from QGIS.
In another software package (with no georeferencing) I import this GeoTIFF as a ground plane; it is scaled correctly in meters.
I add some points over the top & I export these as a CSV file, units are meters.
Essentially, this CSV file is using a local grid.
Can I somehow assign the same coordinate system to this CSV? In my mind, I'm happy to treat the TIFF and CSV as if they are flat.
I have been using the Geoscience "create local CRS" but it would be easier if I can copy some metadata or similar and avoid the clunky workflow.
