randy	c6e4a455b6	Split offline hiking trails per country, add a picker instead of one big file ... data/hiking_trails.geojson is now data/hiking_trails/<CODE>.geojson — one file per country instead of a merge, generated per-source (PmtilesBuilder.extract_hiking_trails), cached the same way geofabrik_cache is (skipped once a country's own extract is already newer than its source .osm.pbf, so growing the selection by one country only re-extracts that one). GET /api/hiking-trails now lists available country codes instead of a single file's status. The Overlays panel's "Hiking trails" item becomes an expandable per-country checklist once any offline extract exists (same shape as Radar's own expand), replacing the plain on/off checkbox — nobody covering a dozen countries' worth of offline map data needs all of their hiking trails loaded and parsed at once, so each ticked country fetches its own GeoJSON independently instead. HikingTrails.extract_merged (server-side multi-country merge, no longer needed now that the client picks per country) removed again. Verified the new extract_hiking_trails + caching skip live on brick against a real cached country PBF.	2026-09-13 11:17:05 +02:00
randy	079ac37787	Wire offline hiking trails into the real build, API, and renderer ... data/hiking_trails.geojson now generates automatically as the last step of every offline.pmtiles build (PmtilesBuilder.extract_hiking_trails, best-effort — a failure here doesn't fail the whole build), merged across all selected countries with cross-border dedup by OSM relation id (HikingTrails.extract_merged). Served at GET /tiles/hiking_trails.geojson and GET /api/hiking-trails, fetched client-side only once the overlay is actually toggled on. hiking_trails.js now prefers this local file whenever it exists, regardless of which base map (online/offline) is active — same "prefer local when available" story as HillshadeControl already uses for terrain. Offline click hit-tests the real vector layer directly (queryRenderedFeatures) instead of querying Overpass — instant, no network. Coordinates are rounded to 5dp to keep the combined file smaller; colour tag values are normalized against a known-safe set before ever reaching a style paint property. Verified extract_merged (new: combines multiple countries' extracts, dedupes overlapping relations) against two real cached country PBFs on brick directly, not just fixtures.	2026-09-13 10:31:59 +02:00
randy	714795d52b	Prototype: extract offline hiking trails from the Geofabrik PBF we already have ... No custom Planetiler profile needed after all — Maptool::HikingTrails runs osmium tags-filter r/route=hiking against the same .osm.pbf PmtilesBuilder already downloads per country for offline.pmtiles, then osmium cat -f opl (locations_on_ways=true) to get member-way geometry back as plain text, no separate node-id lookup table to build. No general OSM tool stitches a route relation into one line (routes are a semantic grouping, not a geometry type) — parse_opl does that walk itself, same as the Overpass-based click handler already does client-side. Kept pure/testable apart from the two osmium subprocess calls, mirroring OverpassPois.fetch vs .to_geojson. rake hiking:trails[pbf,out] to try it by hand against a real cached extract. Not wired into the actual offline build or rendering yet — still just a prototype, per TODO.adoc.	2026-09-13 09:18:50 +02:00
