Hello Ed,

v.in.tig.basic doesn't create a cats file. v.support creates topology
information.  Please see 
for an example of how to create a cats file.  If you need
more information, let me know.

Subject: [GRASSLIST:1846] trouble with TIGER data

I have imported vector data from TIGER type 1 and type 2 files using
v.in.tig.basic.  I then ran v.support on each map imported.  But, when I
run d.what.vect GRASS complains that cats support is missing.  I am
confused here as I thought that v.support was supposed to do this.

What am I missing here?  What do I have to do to get the dig_cats files
build for these TIGER maps?
