# v.out.svg(1grass)

Exports a vector map to SVG file.

## 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
```
