I have a PDF file with a map, but without georeferenced parameters.
I know what coordinate reference system the PDF-map is drawn in.
Now I would like to georeferenced that PDF file, just add needed information.
I have the coordinates for the 4 corners in WGS84.
I do not want to use gdalwarp as it warps the picture.
I only want to add the georeferenced to the PDF file, is that possible with
GDAL?
gdal_translate has lots of options for adding a georeference.
I don't know what would happen for a vector pdf, but if it is
a raster there should heno problem translation from a pdf to
a pdf.
Note that you need the corners of the image file;
many maps have a border, so the corners of the map
may not be the same.
