v.out.svg.1grass - Man Page

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=nameÂ [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=nameÂ [required]: Name for SVG output file
type=stringÂ [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
