       This  program  imports  Census  line  features  from TIGER
       records type1 and type2 into GRASS  vector  format.   Both
       pre-Census and post-Census data formats can be used.  Spe-
       cific Census Feature Class Codes (CFCC) can  be	extracted
       completely  or  in  various combinations.  These codes are
       described in the TIGER/line Census Files  1990  documemta-
       tion  available	from  the Bureau of the Census.  An addi-
       tional feature code consisting of the three letters  "BOU"
       may  also be specified to extract a county boundary.  Con-
       densed Record 1 files may be imported with  the	-c  flag.
       These files should be identified with a trailing "x" char-
       acter on the filename.

       To extract all Primary (A1) and Secondary (A2) roads  from
       a  county's  TIGER  files  the  following command would be
       used:



	vv..iinn..ttiiggeerr..ssccss ttiigg11==t12113.1 ttiigg22==t12113.2 oouutt==roads
	      ccffcc==A1,A2


       To extract all the Hydrographic	features  in  a  county's
       TIGER files with verbose output:



	vv..iinn..ttiiggeerr..ssccss --vv ttiigg11==t12113.1 ttiigg22==t12113.2 oouutt==hydro
	      ccffcc==H


       To extract the county boundary the command would be:



	vv..iinn..ttiiggeerr..ssccss ttiigg11==t12113.1 ttiigg22==t12113.2 oouutt==bou
	      ccffcc==BOU



NNOOTTEESS
       The  TIGER  files  must in sorted order before being used.
       This can be done by using the following command:

	    sort TGR12113.F21 -o t12113.1
	    sort TGR12113.F22 -o t12113.2

       For consistency the  sorted  file  should  be  written  as
       above.	It  should consist of a 't' followed by the State
       and County FIPS code, then a '.' and then a value to iden-
       tify the record number.


       The  CFCC  code	'BOU' used to extract the County Boundary
       should be used alone as it will result in a  polygon  AREA
       being created.


       Currently output is in UTM only.
