v.out.svg
Exports a vector map to SVG file.
v.out.svg input=name [layer=string] output=name type=string [precision=integer] [attribute=name [,name,...]] [--overwrite] [--verbose] [--quiet] [--qq] [--ui]
Example:
v.out.svg input=name output=name type=poly
grass.script.run_command("v.out.svg", input, layer="-1", output, type="poly", precision=6, attribute=None, overwrite=False, verbose=False, quiet=False, superquiet=False)
Example:
gs.run_command("v.out.svg", input="name", output="name", type="poly")
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
Allowed values: poly, line, point
Default: poly
precision=integer
Coordinate precision
Default: 6
attribute=name [,name,...]
Attribute(s) to include in output SVG
--overwrite
Allow output files to overwrite existing files
--help
Print usage summary
--verbose
Verbose module output
--quiet
Quiet module output
--qq
Very quiet module output
--ui
Force launching GUI dialog

Very quiet module output
Default: False
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
