[GRASSLIST:232] Re: Importing Tiger Data with v.in.ogr

[J. Brian Adams]

In response to all.

I am trying to import raw Tiger Data.   Using awk to extract the  
significant features is what I will have to do.  It is what I did  
when I was a student of John MacKenzie's at Delaware in the mid 90's  
(so be careful of the "very old" adjective.)  His instructions were  
what I used when using the old v.in.tig in Grass 4 and 5.  I had  
assumed that v.in.ogr had eliminated this approach, and thus I was  
hoping to find out if it had.  The documentation v.in.ogr is  
excellent for importing shape files, but it seem very limited (in my  
opinion) when addressing raw Tiger Data.  Thanks for all of your help.
