Convert KML fibre network maps to the Open Fibre Data Standard (OFDS)
Output is generated as OFDS 0.4-compatible JSON and GeoJSON files.
Tune how placemarks are filtered, how nearby nodes are merged, and how line segments become spans. Defaults work for many maps; change these if the preview or output needs tuning.
Separate multiple patterns with ; Leave empty to keep all nodes.
Applies after geometry cleanup; unrelated to Merge nearby nodes above.
