DESCRIPTION

35       r.in.poly  allows  the  creation of GRASS binary raster maps from ASCII
36       files in the current directory containing polygon and linear  features.
37       The  input  file  is a Unix input file, in ascii format, containing the
38       polygon and linear features.  The format of this file is  described  in
39       the section INPUT FORMAT below.
40
41       Number  of  rows  to hold in memory is per default 512.  This parameter
42       allows users with less memory (or more) on their system to control  how
43       much memory r.in.poly uses.
44

INPUT FORMAT

46       The  input  format  for  the input file consists of sections describing
47       either polygonal areas or linear features.  The basic format is:
48       A                      <for polygonal areas>
49           easting northing
50           .
51           .
52           .
53       =   cat# label
54       L                      <for linear features>
55           easting northing
56           .
57           .
58           .
59       =   cat# label
60        The A signals the beginning of a polygon. It must appear in the  first
61       column.   The  L signal the beginning of a linear feature. It also must
62       appear in the first column. The coordinates  of  the  vertices  of  the
63       polygon, or the coordinates defining the linear feature follow and must
64       have a space in the first column and at least  one  space  between  the
65       easting  and the northing. To give meaning to the features, the = indi‐
66       cates that the feature currently being  processed  has  category  value
67       cat# (which must be an integer) and a label (which may be more than one
68       word, or which may be omitted).

EXAMPLE

71       An area described by four points:
72       A
73         591316.80   4926455.50
74         591410.25   4926482.40
75         591434.60   4926393.60
76         591341.20   4926368.70
77       = 42 stadium
