       The GRASS program _v_._d_i_g_i_t_2 is a menu-driven, highly inter-
       active map development program used for	inputting  analog
       map  data  into	a GRASS vector format.	_v_._d_i_g_i_t_2 contains
       programs for vector digitizing, editing, labeling, window-
       ing, and converting vector data to GRASS raster format.


       _v_._d_i_g_i_t_2  consists  of two parts: an initialization proce-
       dure, and a multiple menu-driven environment.

	      The initialization procedure  involves  choosing	a
	      digitizer,  choosing the name of a vector map layer
	      to digitize, and, if needed, registering a  map  to
	      the digitizing surface.

	      The  second  part  of  _v_._d_i_g_i_t_2  is a multiple-menu
	      environment in which digitizing, editing, labeling,
	      and  other options are available. It is within this
	      second portion of _v_._d_i_g_i_t_2 that all vector creation
	      occurs.


NNOOTTEESS
       _v_._d_i_g_i_t_2 was written to optimize digitizing speed and per-
       formance.  It has a convenient graphic display format  and
       very   convenient  windowing  capabilities.  Features  are
       color-coded for ease of identification  and  verification.
       Different  color schemes may be user-chosen to customize a
       digitizing session.


       Area, line, and point features may be  digitized  in  both
       "stream"  and  "point" modes. Both a mouse and a digitizer
       may be used to perform windowing functions.  Labeling  and
       editing are done from within _v_._d_i_g_i_t_2, rather than through
       a separate set of programs.


       _v_._d_i_g_i_t_2 has capabilities that allow users to convert vec-
       tor  map layers to GRASS raster format, to overlay already
       existing vector map layers onto the  feature  being  digi-
       tized,  and  set  a multitude of parameters to customize a
       digitizing session.


       _v_._d_i_g_i_t_2 may be used with or without  a	digitizer.   Many
       options are available if no digitizer is used.


       All options available within _v_._d_i_g_i_t_2 are contained within
       ten menus.  Movement from menu to menu is done by  chosing
       the movement options specified at the bottom of each menu.
