input=name [required]

Name of input vector map
Or data source for direct OGR access


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 output vector map

from_type=string [required]

Feature type to convert from
Options: point, line, boundary, centroid, face, kernel
Default: line

to_type=string [required]

Feature type to convert to
Options: point, line, boundary, centroid, face, kernel
Default: boundary


v.type changes the type of geometry primitives.


Convert lines to area boundaries

v.type input=map_l output=map_b from_type=line to_type=boundary

In order to create areas, centroids must be added with v.centroids.
