NAME

v.parallel - Creates parallel line to input vector lines.

KEYWORDS

vector, geometry, buffer, line

SYNOPSIS

v.parallel

v.parallel --help

v.parallel [-rb] input=name [layer=string] output=name distance=float [minordistance=float] [angle=float] side=string [tolerance=float] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:

-r: Make outside corners round
-b: Create buffer-like parallel lines
--overwrite: Allow output files to overwrite existing files
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

input=name [required]: Name of input vector map; Or data source for direct OGR access
layer=string: Layer number or name ('-1' for all layers); A single vector map can be connected to multiple database tables. This number determines which table to use. When used with direct OGR access this is the layer name.; Default: -1
output=name [required]: Name for output vector map
distance=float [required]: Offset along major axis in map units; Options: 0-100000000
minordistance=float: Offset along minor axis in map units; Options: 0-100000000
angle=float: Angle of major axis in degrees; Default: 0
side=string [required]: Side; Options: left, right, both; Default: right; left: Parallel line is on the left; right: Parallel line is on the right; both: Parallel lines on both sides
tolerance=float: Tolerance of arc polylines in map units; Options: 0-100000000
