I am having difficulty in georeferencing an existing tiff (already has georeference information - but is out of alignment). Using the georeference plug-in I can create the map's GCP in the 4 corners and run the transformation (using WGS84). However, even trying other transformations I get a map that is not georeferenced to the Lat & Long. The Lat / Long of the original map shows 26.00, -25.00 (top left corner), the georeference after transformation is 974, -747.
How can I get the transformation to reflect Lat / Long as per the original georeference as all I am trying to achive is a re-aligned map?
