They're no help because data comes from different sources.

Anyway, I've found the reason for my problems: the work flow I used. Trying
to switch both location and mapset using g.mapset didn't work; I'd still be
in the original mapset and managed to mess up a lot of the imports and

What I now do is start grass passing a specific location and mapset. When
I'm finished, I exit and restart grass specifying the new location and

Some of the maps are slightly rotated or have spaces between them and
adjacent ones. I'm ignoring all of this.

Thanks very much for the help you and Markus M have provided.
