Geo/tools/ is now every geographic script, with Geo/README.md documenting each one; the Blender-side builders moved beside their outputs in Art/blender/*/ and import their helpers from Geo/tools/osm_common.py. That module gains to_unreal_local() and to_blender_local(): the only place in the repository that multiplies metres by 100, so a second silent scale cannot be introduced. block_height_report.py adds height provenance for the block — 3 of 15 buildings have no height data and render at a placeholder 6.4 m. asset_metadata.py writes and audits <asset>.geo.json sidecars; four now exist (hero-facade, terrain, street, blockout) and the audit recomputes each centre from the origin, failing anything that disagrees.

"""Report which block buildings have real height data and which are guesses.
|
|
|
|
Usage:
|
|
Geo/tools/block_height_report.py Geo/raw/osm-api-map-2026-11-06.osm
|
|
|
|
`height` and `building:levels` are the only height evidence OSM carries. Where
|
|
neither exists, Blosm falls back to `defaultLevels * levelHeight`, which is a
|
|
placeholder: the demo renders a constant-height block instead of a real skyline.
|
|
This tool lists every building in the demo bounds with its height source, so the
|
|
substitutions are visible and measurable rather than buried in the model.
|
|
|
|
Exit code is 0 either way; the count of guessed buildings is the deliverable.
