39
40   Parameters:
41       input=name [required]
42           Name of input vector map
43           Or data source for direct OGR access
44
45       layer=string
46           Layer number or name (’-1’ for all layers)
47           A  single  vector map can be connected to multiple database tables.
48           This number determines which table to use. When  used  with  direct
49           OGR access this is the layer name.
50           Default: -1
51
52       output=name [required]
53           Name for output vector map
54
55       distance=float [required]
56           Offset along major axis in map units
57           Options: 0-100000000
58
59       minordistance=float
60           Offset along minor axis in map units
61           Options: 0-100000000
62
63       angle=float
64           Angle of major axis in degrees
65           Default: 0
66
67       side=string [required]
68           Side
69           Options: left, right, both
70           Default: right
71           left: Parallel line is on the left
72           right: Parallel line is on the right
73           both: Parallel lines on both sides
74
75       tolerance=float
76           Tolerance of arc polylines in map units
77           Options: 0-100000000
78

DESCRIPTION

80       v.parallel  creates  parallel lines to the input vector lines which can
81       be used as half-buffers.
82

NOTES

84       Usage of -b flag will overrule the side parameter.
85

KNOWN ISSUES

87       There is a problem with side-offset parallel line generation for inside
88       corners.  To avoid this problem, the -b flag might be used.
