v.multi2singlepart

Split multi-part polygons into single-part polygons.

v.multi2singlepart input=name output=name [--overwrite] [--verbose] [--quiet] [--qq] [--ui]

Example:

v.multi2singlepart input=name output=name

grass.script.run_command("v.multi2singlepart", input, output, overwrite=False, verbose=False, quiet=False, superquiet=False)

Example:

gs.run_command("v.multi2singlepart", input="name", output="name")

Parameters

Command linePython (grass.script)

input=name [required]
    Name of input vector map
    Input vector layer
output=name [required]
    Output vector layer
--overwrite
    Allow output files to overwrite existing files
--help
    Print usage summary
--verbose
    Verbose module output
--quiet
    Quiet module output

input : str, required
    Name of input vector map

    Used as: input, vector, name
output : str, required
    Output vector layer
    Used as: output, vector, name
overwrite: bool, optional
    Allow output files to overwrite existing files
    Default: False
verbose: bool, optional
    Verbose module output
    Default: False
quiet: bool, optional

DESCRIPTION

v.multi2singlepart creates a vector layer containing singlepart polygon features generated by separating the multipart features of the input vector layer. The attributes of the input layer will be maintained in the output vector layer. Singlepart features will not be affected.

From multipart to singlepart polygons.

NOTES

To go from singlepart to multipart features, use the v.dissolve function (see example below).

EXAMPLES

The example uses the layer boundary_municp from the North Carolina dataset. You can download the sample data set from the GRASS GIS website

v.dissolve input=boundary_municp column=MB_NAME output=bnd_municp_dis
v.multi2singlepart input=bnd_municp_dis output=bnd_municp_split
