Generate gtfs.geojson

The repository includes a GTFS-to-GeoJSON generator:

• Script: scripts/generate-gtfs.ps1
• Default source: https://storage.googleapis.com/marduk-production/outbound/gtfs/rb_sky-aggregated-gtfs.zip
• Default output: gtfs.geojson

Run from repository root:

pwsh -File ./scripts/generate-gtfs.ps1

If the feed must be provided locally:

pwsh -File ./scripts/generate-gtfs.ps1 -InputZipPath /path/to/feed.zip

Output format

gtfs.geojson is a GeoJSON FeatureCollection with:

• features containing:
  • stop features (Point) with stop identifiers, names, coordinates, and parent station metadata
  • line features (LineString) with route identifiers/names/type and trip/service metadata
• frequency containing grouped scheduled-service metadata for line/stop frequency calculations
• top-level metadata (generated, source, counts, description)

Generate nvdb.geojson

The NVDB generator fetches speed limits, roundabouts, tunnels, and public-transport hubs for every Bergen bydel. It writes standard GeoJSON, including valid [longitude, latitude] coordinates for point objects.

pwsh -File ./scripts/generate-nvdb.ps1

The script uses areas.geojson as its area source and overwrites nvdb.geojson by default.
