- Replace OSM Overpass transit data with the Rejseplanen GTFS feed
(routes keyed by (agency, short name); styles from modes.yaml)
- Draw one shape per (style, ref, direction), choosing the shape that
serves the most in-area stops so lines pass the stops we show
- Collapse stops by names (verified unambiguous); prune stops whose
serving refs have no drawn line within 300 m
- Patch Københavns Havn + Nordhavn into the area polygon so ferry
routes and sub-harbour metro tunnels survive clipping; 100 m buffer
closes relation boundary slivers
- Drop OSM download pipeline; keep tiled basemap
Replaces distance-based clustering with route-membership grouping:
- download_osm.py: collect route_refs per stop node; use platform roles
for bus stops, stop roles for rail stops
- prepare.py: carry route_refs through to master.gpkg
- render.py: group_by_route_membership() uses union-find to cluster
same-name stops sharing at least one route into one marker; stops on
disjoint routes are kept separate. No distance threshold needed.
Results: 786 bus platforms -> 465 markers (was 1610 -> 781).
Veksøvej: 2 platforms sharing routes 2A+5C -> 1 marker.
Peter Bangs Vej: 7 platforms on routes 10/21/22/4A/7A -> 2 markers.
