Terrain is clipped, reprojected, resampled and simplified. DSM includes vegetation/buildings; it is not surveyed bare-earth terrain.

Derived water database: /races/paranesti/water.json (ODbL).
OSM source extract: /data/osm-waterways-source.geojson (ODbL).
Mapped centre lines only; water width/level/appearance are illustrative.

Adaptations and hashes: /models/provenance.json and /textures/provenance.json.

GPX: supplied by the project user. Official start and selection of the first 5 km confirmed by the user on 2026-10-15. No independent survey is claimed.

Imagery was consulted for visual review only. No Esri imagery pixels are bundled or used as runtime textures.

Development extension — complete GPX and authoring review (2026-10-16):
The complete selected GPX track is 24,411.637 m. A separate 0.126 m track segment is not joined automatically. The original supplied file is preserved in project inputs.
Full-route derived water database (ODbL): /races/paranesti-full/water.json.
Review candidate database (ODbL): /reviews/paranesti-full/scene-features.geojson.
The review database includes source URLs, source hashes and attribution. It is not a satellite-verified inventory. A conservative subset is instantiated as illustrative procedural props.
The authoring page links to satellite views in Google Maps using documented Maps URLs. No Google or Esri imagery is bundled, cached by the Factory, used as terrain textures, or automatically analyzed by this tool.
The scene catalog distinguishes implemented procedural models from planned groups. Houses, bridge decks/rails, gates, poles/pylons, a fountain and a chapel template are generated locally in code; no new prop GLBs were downloaded. Derived placement database (ODbL): /races/paranesti-full/props/index.json and its referenced tile batches. Residential use may be inferred from building=yes inside mapped residential landuse; it is not verified from imagery. Bridge decks follow the approximate terrain and do not reproduce surveyed elevations or structural details.

Settlement road extension (2026-10-16):
Derived road/coverage database (ODbL): /races/paranesti-full/urban/index.json and referenced tile surface batches. Mapped road centrelines are buffered with tagged or assumed widths, restricted to mapped residential areas plus 18 m. Surface materials may be assumed from road class. Small procedural house aprons are illustrative; they do not represent surveyed yards or legal property boundaries. No satellite pixels are bundled. The terrain and GPX remain unchanged.

Railway and sky extension (2026-10-16):
Mapped rail geometry and gauge tags are derived from OpenStreetMap in the urban index/tile database (ODbL). Visible main lines, sidings and rail bridges are illustrative terrain-draped surfaces; tunnels are omitted. Untagged gauge defaults to 1.435 m. No train, signalling or engineering-grade rail/bridge reconstruction is included.
The four procedural sky/light presets, moon surface detail and stars are generated in application code; no downloaded sky images are bundled. Their directions, angular sizes, colours and phases are artistic, not astronomical predictions.
