       The  GRASS  tool  _r_._d_i_g_i_t  provides the user with a way to
       draw lines, areas, and circles on a monitor screen, and to
       save  these  features  in  a cell file.	Lines, areas, and
       circles are to be drawn using a pointing  device  (mouse).
       A mouse button menu indicates the consequences of pressing
       each mouse button.  The user is	requested  to  enter  the
       category  number associated with the line, area, or circle
       subsequently drawn by the user.	Lines, areas, and circles
       are  defined  by  the  series of points marked by the user
       inside the map window.  _r_._d_i_g_i_t will close areas when  the
       user  has  not.	By drawing a series of such features, the
       user can repair maps, identify areas of interest, or  sim-
       ply draw graphics for advertisement.  When drawing is com-
       pleted, a raster map based on the user's  instructions  is
       generated.   It	is available for use as a mask, in analy-
       ses, and for display.


       Digitizing is done in a "polygon" method.   Each  area  is
       circumscribed  completely.  Two or more areas and/or lines
       might define a single part of a map.   Each  part  of  the
       map, however, is assigned only the LAST area or line which
       covered it.

	      Choose to define an area or line, quit, or  finish.
	      If  you  quit,  the session exits with nothing cre-
	      ated.  If you choose to finish (_d_o_n_e), you will  be
	      prompted	for  a new map name;  the new map is then
	      created.

	      If you choose to make an	area  or  line	you  must
	      identify the category number for that area or line.

	      Using the mouse trace the line or circumscribe  the
	      area; or, finish (go to Step 1).
