Add south_bound_lat to modes.yaml and a load_south_bound() helper in
prepare.py. When set, the area geometry is intersected with the north
half-plane above the cutoff, so all downstream clipping (lines, stops,
stations) cascades automatically.
Removed: 94 bus stops (including Skyttehøj), 1 station (Vestamager),
and line segments south of the boundary (Metro M1 tail, buses 32-36).
- modes.yaml: bus_whitelist (A-buses + selected refs) and exclude list
(Snälltåget 083 night train — sparse crow-fly stubs)
- prepare.py: drop degenerate crow-fly shapes below 0.05 pts/km; apply
bus whitelist and route exclusions from modes.yaml
- export_google_mymaps.py: new script — master.gpkg -> KML for Google
My Maps import (stops, routes, boundary, coastline layers)
- coastline.kml: reference coastline layer for the KML export
- .gitignore: also ignore generated output/*.kml
- 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
