NAME
v.parallel - Creates parallel line to input vector lines.
KEYWORDS
vector, geometry
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] [--verbose] [--quiet]
Flags:
- -r
- Make outside corners round
- -b
- Create buffer-like parallel lines
- --overwrite
- Allow output files to overwrite existing files
- --verbose
- Verbose module output
- --quiet
- Quiet module output
Parameters:
- input=name [required]
- Name of input vector map
- Or data source for direct OGR access
- layer=string [required]
- 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
DESCRIPTION
v.parallel creates parallel lines to the input vector lines which
can be used as half-buffers.
