v.in.tig.basic (GRASS4.1) or v.in.tiger12 (GRASS4.0) will create vector maps
with TIGER/Line line features, i.e. roads, streams, etc. However, the TIGER/
Line ID numbers (TLID) are used for attributes, and there are no categories
(as each attribute is unique!). I do not know how to build census blocks as
attributed areas in GRASS; however, ArcInfo does this quite well, so if you
have any buddies with Arc...

I will be writing some shell scripts to allow categories to be used with the
vector layers created by v.in.tig.basic (line features only!). I'll post more
info when these are completed.
