MULTIPLE ATTRIBUTES FOR RASTER FILES

I need to represent multiple attributes in GRASS raster files.
For example, surface roughness, dielectric constant, veg. cover, etc.
I can think of two ways to do this:
1. create multiple raster maps for the terrain, one for
each attribute. The attribute in each file stores the value
for the original attribute.
2. have the single attribute in the raster file store the
values of all the attributes after encoding them, e.g.
the first digit in the attributes represents roughness,
the second, veg. cover, and so on.
I can understand that the second method is extremely dirty in terms
of simplicity, expandability, etc. But I would like to know if anyone
has tried it. ANY other comments are welcome.
