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 features
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
