Matt	bc463188d5	feat(offroute): Phase O4 — multi-mode cost functions (foot/mtb/atv/vehicle) ... - Add ModeProfile dataclass for data-driven mode configuration - Implement three speed functions: * Tobler off-path hiking (foot) * Herzog wheeled-transport polynomial (mtb/atv) * Linear speed degradation (vehicle) - Add WildernessReader for PAD-US Des_Tp=WA wilderness areas - Mode-specific terrain friction overrides: * Forest impassable for ATV/vehicle, high friction for MTB * Wetland/mangrove impassable for all wheeled modes - Trail access rules: * Foot trails (value 25) impassable for ATV/vehicle - Wilderness blocking for mtb/atv/vehicle modes - Vehicle mode allows flat grassland/cropland traversal - Memory optimization: limit entry points, constrain bbox size - Update router to pass mode and wilderness to cost function - Add vehicle to API mode validation Validated all four modes with test route: - foot: 0.46km off-network, 12.11km network, 89% on trail - mtb: 0.47km off-network, 13.13km network, 90% on trail - atv: 0.47km off-network, 12.81km network, 90% on trail - vehicle: 0.46km off-network, 12.81km network, 89% on trail Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-05-08 14:11:56 +00:00
Matt	e0eedcedfd	feat(offroute): Phase O2c — PAD-US barriers with three-mode boundary respect ... - Add barriers.py: PAD-US raster reader + build_barriers_raster() function - Rasterize PAD-US Pub_Access=XA (Closed) polygons to CONUS GeoTIFF - Modify cost.py: boundary_mode parameter (strict/pragmatic/emergency) - strict: private land = impassable (np.inf) - pragmatic: private land = 5x friction penalty (default) - emergency: private land barriers ignored - Modify prototype.py: three-way comparison output - Output: padus_barriers.tif at /mnt/nav/worldcover/ (144MB, ~33m resolution) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-05-08 06:56:36 +00:00
