[GRASS-user] Managing UTM different zones

[Hamish]

IIUC generally it is not a good idea to stray more than half a zone
beyond your central UTM zone. UTM is built for use in narrow strips and
local maps. For continental scale work it would be better to reproject
into an all covering projection, perhaps LCC or Albers.

I suggest that you ask the experts on the PROJ.4 mailing list for a
commonly used projection for the entire Med, or what should go into a
custom one.
