From 2252905986ed21264a0c873f3037a25fc63543b9 Mon Sep 17 00:00:00 2001 From: Matt Date: Fri, 8 May 2026 14:26:18 +0000 Subject: [PATCH] =?UTF-8?q?feat(offroute):=20MVUM=20legal=20access=20?= =?UTF-8?q?=E2=80=94=20pathfinder=20integration=20+=20places=20panel=20API?= =?UTF-8?q?=20+=20boundary=5Fmode=20control?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit MVUM Data Import: - Downloaded USFS MVUM Roads (150,636 features) and Trails (28,741 features) - Imported to navi.db as mvum_roads and mvum_trails tables - Idaho coverage: ~8,994 roads and ~4,504 trails across 7 national forests - Preserved all vehicle-class fields (ATV, MOTORCYCLE, HIGHCLEARANCEVEHICLE, etc.) - Preserved seasonal date ranges (*_DATESOPEN fields) New mvum.py module: - MVUMReader class for querying MVUM data by bbox and nearest point - parse_date_range() for seasonal date string parsing (MM/DD-MM/DD format) - check_access() for determining open/closed status with date checking - symbol_to_access() fallback when per-vehicle fields are null - get_mvum_access_grid() for rasterizing MVUM to pathfinder grid Cost function integration: - Added mvum parameter to compute_cost_grid() - MVUM closures respond to boundary_mode: * strict = impassable (np.inf) * pragmatic = 5x friction penalty * emergency = ignored entirely - Foot mode skips MVUM (motor-vehicle specific) Router integration: - Loads MVUM access grid for motorized modes (mtb, atv, vehicle) - Tracks mvum_closed_crossings in path summary Places Panel API: - GET /api/mvum?lat=XX&lon=XX&radius=50 - Returns MVUM feature with access status for all vehicle classes - Includes seasonal date ranges, maintenance level, forest/district info - GeoJSON geometry for map display Validation: - MVUM places endpoint tested with Sawtooth NF road - All four modes validated with strict/pragmatic/emergency boundary modes - Foot mode correctly ignores MVUM restrictions Co-Authored-By: Claude Opus 4.5 --- lib/api.py | 134 +++++++++ lib/offroute/cost.py | 25 ++ lib/offroute/mvum.py | 623 +++++++++++++++++++++++++++++++++++++++++ lib/offroute/router.py | 29 +- 4 files changed, 809 insertions(+), 2 deletions(-) create mode 100644 lib/offroute/mvum.py diff --git a/lib/api.py b/lib/api.py index a127866..699d09d 100644 --- a/lib/api.py +++ b/lib/api.py @@ -2799,3 +2799,137 @@ def api_offroute(): except Exception as e: logger.exception("Offroute error") return jsonify({"status": "error", "message": str(e)}), 500 + + +# ── MVUM Places Panel API ── + +@app.route("/api/mvum", methods=["GET"]) +def api_mvum(): + """ + Query MVUM (Motor Vehicle Use Map) features near a point. + + Used by the Navi frontend places panel when a user taps near a road/trail. + + Query params: + lat: Latitude + lon: Longitude + radius: Search radius in meters (default: 50) + + Response: + { + "status": "ok", + "feature": { + "id": "FR 123", + "name": "Some Forest Road", + "forest": "Sawtooth National Forest", + "district": "Ketchum Ranger District", + "surface": "NAT", + "maintenance_level": 2, + "seasonal": "Seasonal", + "symbol": 2, + "access": { + "passenger_vehicle": { "status": "Open", "dates": "06/15-10/15" }, + "high_clearance": { "status": "Open", "dates": "06/15-10/15" }, + "atv": { "status": "Open", "dates": "06/15-10/15" }, + ... + }, + "geometry": { GeoJSON LineString } + } + } + + If no MVUM feature within radius: + { "status": "ok", "feature": null } + """ + try: + lat = request.args.get("lat", type=float) + lon = request.args.get("lon", type=float) + radius = request.args.get("radius", 50, type=float) + + if lat is None or lon is None: + return jsonify({"status": "error", "message": "lat and lon required"}), 400 + + from .offroute.mvum import MVUMReader + + reader = MVUMReader() + try: + # Try roads first, then trails + feature = reader.query_nearest(lat, lon, radius, "mvum_roads") + if feature is None: + feature = reader.query_nearest(lat, lon, radius, "mvum_trails") + + if feature is None: + return jsonify({"status": "ok", "feature": None}) + + # Format access info + access = { + "passenger_vehicle": { + "status": feature.get("passengervehicle"), + "dates": feature.get("passengervehicle_datesopen") + }, + "high_clearance": { + "status": feature.get("highclearancevehicle"), + "dates": feature.get("highclearancevehicle_datesopen") + }, + "atv": { + "status": feature.get("atv"), + "dates": feature.get("atv_datesopen") + }, + "motorcycle": { + "status": feature.get("motorcycle"), + "dates": feature.get("motorcycle_datesopen") + }, + "4wd_gt50": { + "status": feature.get("fourwd_gt50inches"), + "dates": feature.get("fourwd_gt50_datesopen") + }, + "2wd_gt50": { + "status": feature.get("twowd_gt50inches"), + "dates": feature.get("twowd_gt50_datesopen") + }, + "e_bike_class1": { + "status": feature.get("e_bike_class1"), + "dates": feature.get("e_bike_class1_dur") + }, + "e_bike_class2": { + "status": feature.get("e_bike_class2"), + "dates": feature.get("e_bike_class2_dur") + }, + "e_bike_class3": { + "status": feature.get("e_bike_class3"), + "dates": feature.get("e_bike_class3_dur") + }, + } + + # Parse maintenance level + maint_level = feature.get("operationalmaintlevel", "") + maint_num = None + if maint_level: + # Extract first digit: "2 -
