Description
The tool allows one to extract closed lines from the input shapefile. Closed lines are detected by examining the distance between the first and last line vertex. The 'tolerance' parameter describes the maximum distance allowed between the first and last line vertex. The 'maximum length' parameter can be used to exclude long lines.
