input=name [required]

Name of input vector map
Or data source for direct OGR access


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


Coordinate precision
Default: 6


Attribute(s) to include in output SVG


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).


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
