Bend bike routes + classified network overlay (Casual mode)#93
Merged
Conversation
Two OSM-derived additions to Bend's Casual mode, inspired by bendbikes.org (data © OpenStreetMap; credited on the About page): - Classified bike-network overlay: scripts/build_bend_bike_network.py grades ~6.2k OSM ways in a Bend bbox into five comfort tiers (paved/unpaved trail, bike lane, calm street, use caution) -> public/data/bend/bike-network.geojson. ensureBendNetworkSource renders two stacked line layers, toggled from the Casual sidebar (BikeNetworkLayer + 5-class legend), city-gated by bikeNetworkUrl. - Greenway routes: scripts/build_bend_routes.py stitches 8 named multi-use paths (Deschutes River Trail, Discovery, Rimrock, Haul Road, ...) -> routes.geojson + bend/bike-routes.data.ts. ensureInlineRoutes attaches a per-route line/casing/hit layer from GeoJSON keyed by id, so the existing route select/zoom/click flow works unchanged. City-gated by bikeRoutesUrl. plan.md captures the multi-city roadmap.

- Lazy-attach the multi-MB network GeoJSON on first toggle instead of at startup, so users who never open the overlay don't download it (#1). - Classify untagged path/footway/bridleway as unpaved (only explicitly-paved surfaces are 'paved trail'); cycleways still default paved (#2). - Share a firstSymbolLayerId() helper for label-aware layer insertion (#3). - Consolidate slugify into scripts/_geo.py; build_bend_routes reuses line_length_m from osm_trail_elevation (#4, #8). - Reuse buildColorExpression for the network color; collapse the network and inline-route layer creation into spec-driven loops (#5, #7). - De-Bend the generic mechanism: bend-network.ts -> bike-network.ts, BEND_NETWORK_* -> BIKE_NETWORK_*, ensureBendNetworkSource -> ensureBikeNetworkSource, event bendNetwork -> bikeNetwork, source ids -> bike-network-source / inline-routes-source; build script takes --region/--out for reuse (#6). - Key the Overpass cache by query hash so a different --bbox doesn't reuse a stale extent (P3). - Export reads inline-route geometry from the GeoJSON when bikeRoutesUrl is set, so Bend's /export finds features and enables GPX/SVG (P2).

Adds Bend's Casual-mode cycling content — both rebuilt from OpenStreetMap and inspired by bendbikes.org (data © OpenStreetMap; credited on the About page). Complements the curated MTB pane that landed in #91.
What's in it
1. Classified bike-network overlay
A toggleable overlay that color-codes Bend's streets/paths by comfort, like a low-stress-network map.
scripts/build_bend_bike_network.py— one Overpass query for a Bend bbox, grades ~6.2k OSM ways into five tiers via OSM tags (LTS-lite): paved trail / unpaved trail / bike lane / calm street / use caution →public/data/bend/bike-network.geojson(489 KB gzipped).ensureBendNetworkSource/setBendNetworkVisiblerender two stacked line layers (base tint + infra on top), beneath labels.BikeNetworkLayer(toggle + color legend); city-gated bybikeNetworkUrl(hidden for Chattanooga).2. Greenway routes
Eight named multi-use paths surfaced in the routes sidebar (Chattanooga-parity), distinct from the MTB singletrack.
scripts/build_bend_routes.py— collects each route's segments by OSM name →public/data/bend/routes.geojson+bend/bike-routes.data.ts(Deschutes River Trail 13.2 mi, Discovery, Rimrock, Haul Road, Larkspur, Cascade Highlands, Tumalo Creek, West Bend).ensureInlineRoutesattaches a per-route line/casing/hit layer from GeoJSON keyed byid, so the existing route select/zoom/click/highlight flow works unchanged. City-gated bybikeRoutesUrl(Chattanooga keeps its Studio-layer routes).Architecture notes
CityDatafields (bikeNetworkUrl,bikeRoutesUrl) — no impact on Chattanooga.Verification
