[GRASS-user] howto import OS mastermaps

[Jim Maas]

I'm learning grass had have downloaded some OS mastermaps from 
http://digimap.edina.ac.uk/ .  They are comprised of a "mastermap" 
directory name, which holds a "sd" directory, which holds a "sd##" 
directory, which holds several twf, tif, tif.aux.xml, and .ovr files, 
presumably one set of these for each tile?

I've googled and read and tried many import options but can not figure 
out how to import these into grass 7.0.2.  Presumably they are a sort of 
raster file?  Any suggestions on how to import them? I know several of 
the areas I want to look are comprised of multiple tiles.

Thanks

J
