Tokyo Station, approximately 300m x 300m. 1 metre per block.
The ZIP contains a Sponge Schematic v2 (.schem, Minecraft Java 1.21.1,
DataVersion 3955), this notice and the source sample JSON.

Source URL and SHA-256 are in sample.sources.plateau in the included JSON.
Modified by VANEROLA: area extraction, local coordinate conversion,
roof/wall/ground surface extraction and 1m voxelization. Colours are illustrative.
This is NOT an unmodified official PLATEAU model. Colours and decorative window
patterns are illustrative; they do not reproduce real facades, windows or interiors.

2. Terrain / 地面

Geospatial Information Authority of Japan (GSI) elevation tiles, processed by VANEROLA

Fetched tile URLs are recorded in sample.terrain.tiles in the included JSON.
Sampled on a 5m grid, bilinearly interpolated and rounded to metre blocks.
The .schem uses a local vertical origin, not Minecraft's sea level.
Interpolation and voxelization do not increase survey accuracy.

3. Map features / 地図

The OSM portion of the included JSON is made available under ODbL 1.0.
It includes filtered node/way/relation data for the sample area.
OSM mode: standard CityTrace quality 3, estimated missing heights / roof detail.
PLATEAU mode: uses OSM ground features for roads / water and estimated OSM
buildings where they do not touch the PLATEAU building footprint. The overlap
check is approximate and connected buildings may be grouped or omitted.
The PLATEAU and GSI portions retain their respective source terms.

4. Prototype limitations / 試作の制約
Data retrieval timestamp, boundaries and projection constants are in the JSON.
PLATEAU and OSM were surveyed at different dates and may differ in coverage.
Both outputs use CityTrace's approximate local metres-per-degree projection.
There is no validated accuracy score. Features are clipped at the sample boundary.
The preview samples top surfaces and visible column faces; it is not a full mesh.
Hidden surfaces, overhangs and cavities may be missing or inaccurately displayed.
The PLATEAU .schem retains surface-shell voxels (not invented interior floors).
LOD2 does not reproduce every real-world detail, and the data may contain gaps.
The normal CityTrace generator is unchanged. This sample is not nationwide support.
