To change the name from 'OSM street map', use the --description option
when combining files too.

   --description="Sweden OSM map" --gmapsupp 
contourdir/srtm/gmapsupp.img countrydir/...

If you want the street map and the contour map to be separate, I think
you will need to set family-id to something different in the contour

I'm sure that someone else will know more about how to achieve what
you want than me.
