Segments to Polygons

The Segments to Polygons operation automatically polygonizes a supposedly error free segment map. The operation is designed to be used after you have imported vector files from another package. All segments in the segment map must be connected to other segments or to themselves (islands) by nodes; dead ends, self overlap and/or intersections are not allowed. A mask can be specified to polygonize specific segments.

Tips:

• Segment editor : Check Segments: open the segment map in the segment editor and use Check Segments to check the segments yourself before polygonization and have the possibility to interactively correct any erroneous segments yourself.
• Segment editor : Polygonize: open the segment map in the Segment editor and use Polygonize to polygonize segments while having the possibility to interactively correct erroneous segments yourself.
