SYNOPSIS
v.multi2singlepart
v.multi2singlepart --help
v.multi2singlepart input=name output=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
- Input vector layer
- output=name [required]
- Output vector layer
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.
To go from singlepart to multipart features, use the
v.dissolve function (see example below).
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
v.dissolve
