  • What do you actually mean by "I've Geo-referenced raster"? Have you georeferenced your raster by yourself of have you received the raster somewhere as already georeferenced?

In the Georeferencer tool, there's a button to save the ground control points.

enter image description here

Even if you didn't save the GCP points while the Georeferencer was open, they should be saved "in a separate text file ([filename].points) usually together with the raster image." (source: QGIS Manual)

Eg, I recently georeferenced a raster, and saved it as "Roadmap_modified.tif". Even though I didn't save the GCP points, there's a file called "Roadmap_modified.tif.points" in the same file as the georeferenced raster.

  • I don't have *.points file ! Jul 12, 2019 at 1:05
  • That's unfortunate. The manual does say that the GCP are usually saved together with the raster image. That implies they might be saved somewhere else, so you could try searching your computer for a *.points file. Other than that, I don't have any more suggestions.
