v.out.svg(1)

NAME
v.out.svg - Exports a vector map to SVG file.

KEYWORDS
vector, export, output

SYNOPSIS
v.out.svg
v.out.svg --help
v.out.svg input=name [layer=string] output=name type=string [precision=integer] [attribute=name[,name,...]] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

  Flags:

--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 SVG output file

type=string [required]
    Output type
    Defines which feature-type will be extracted
    Options: poly, line, point
    Default: poly

precision=integer
    Coordinate precision
    Default: 6

attribute=name[,name,...]
    Attribute(s) to include in output SVG

DESCRIPTION
v.out.svg converts GRASS vector data to SVG (Scalable Vector Graphics) code notation. In particular, it

    •   converts GRASS line, boundary, area, point, centroid objects to SVG <path />, <circle /> elements,

    •   reduces coordinate precision in SVG-output to save bandwidth,

    •   extracts GRASS attributes to gg:name="value" attributes.
The precision parameter controls the number of decimals for coordinates output (precision=0 corresponds to integer precision in the output SVG file).

EXAMPLE

Export polygons from GRASS vector map soils (Spearfish sample data) to SVG format:

v.out.svg input=soils output=/tmp/output.svg type=poly

Export lines from GRASS vector map t_hydro (Spearfish sample data) to SVG format, set coordinate precision to 0:

v.out.svg input=t_hydro output=/tmp/output.svg type=line precision=0

Export points from GRASS vector map archsites (Spearfish sample data) to SVG format, include attribute str1 (name):

v.out.svg input=archsites output=/tmp/output.svg type=point precision=0 attrib=str1
