1.8B+ ray-casted checks per region evaluate near + far vistas, cliffs, valleys, water exposure, and canopy gaps.
Fuses multispectral satellites, aerial RGB, national DEMs, and global nighttime lights to infer openness, relief, foliage, and human activity.
Blocker layers dampen monotonous industrial belts, mega sheds, ports, and elevated highways; rural fades ease transitions near towns.
Highlights include valley floors opening toward mountain walls, ridgeline pullouts, or winding bridge decks suspended above water.

Data fusion: Multi-petabyte imagery, global DEM mosaics, land-cover atlases, and nighttime-light priors are staged into aligned tiles so the scenic values stay consistent from alpine passes to coastal highways.

Blockers & fading: National building footprints, infrastructure registries, and activity maps infer massing, heights, and land-use tone, letting the model down-weight factory belts while easing transitions as roads leave towns.

Computation: The HPC core tiles every region, fans rays along each segment from curb-scale 3 km probes out to 15 km vistas, and merges billions of measurements into the per-segment scenic:t, hex colors, and alpha sent to Mapnik.
