Thank you, Frank. The following seems to have removed only the lat and long details:
for i in *.xmp; do echo "Processing $i"; exiftool -geotag=
"$i"; done
Now I'm back to where I was at the beginning; I must manipulate the
offset so that the photos are moved by a couple of kilometres. Can
you confirm that any repeated tweaks to the offset are cumulative?

This sed-command deletes all lines in the *.xmp with the text-string
"GPS".
I looked into one of my *.xmp-files:
exif:GPSLongitude="8,...E"
exif:GPSLatitude="52,...N">
<darktable:mask_id>
The GPSLatitude-Line ist the last line of the
XML-tag "<rdf:Description>".
The tag-closing ">" in the line will also be deleted.
So the *.xmp gets unreadable.
Try to modify the sed-Command to let the ">" in place.
Or
try to set a single ">" before "<darktable:mask_id>".
Or
maybe it is also possible to use exiv-tools to modify all *.xmp but
not
the raw (which has no GPS-Coordinates).
http://www.exiv2.org/manpage.html :
"exiv2 is a program to read and write ..., XMP metadata and .."
exiv2 -M"set Exif.GPSInfo.GPSLatitude ....
