Cut 

Cut(self, data, options={})

This class targets the following objectives:

  1. Split linestrings given the junctions of shared paths
  2. Identifies indexes of linestrings that are duplicates

The cut function is the third step in the topology computation. The following sequence is adopted:

  1. extract
  2. join
  3. cut
  4. dedup
  5. hashmap

Returns

  • dict

    object updated and expanded with

  • - updated key: linestrings
  • new key: bookkeeping_duplicates

to_dict 

Cut.to_dict(self)

Convert the Cut object to a dictionary.

to_svg 

Cut.to_svg(self, separate=False, include_junctions=False)

Display the linestrings and junctions as SVG.

Parameters

  • separate : boolean

    If True, each of the linestrings will be displayed separately. Default is False

  • include_junctions : boolean

    If True, the detected junctions will be displayed as well. Default is False
