#1818: v.clean: new tool to close lines and turn into area
-------------------------+--------------------------------------------------
Reporter: neteler | Owner: grass-dev@…
     Type: enhancement | Status: new
Priority: normal | Milestone: 7.0.0
Component: Vector | Version: svn-trunk
Keywords: v.clean | Platform: All
      Cpu: All |
-------------------------+--------------------------------------------------
A potentially useful new tool "polygonizer" in v.clean would do:

Examples:
{{{
+----+
| +
| |
+-----+
}}}

or:

{{{
       +
       |
+-------+
| |
| |
+-----+
}}}

  * 1st case: close open line within threshold
  * 2nd case: break line, remove dangles
  * turn line type into boundary type
  * add centroid + cat

Comment(by neteler):

The needed methods may be used from v.edit:

  * break: Break/split vector lines
  * snap: Snap vector features in given threshold
  * connect: Connect two lines
  * chtype: Change feature type (point<->centroid, line<->boundary)
