Retrieved 2026-11-03; regional index dated 2026-11-02. Projected/clipped baseline subset preserves source IDs and tags. Later sports inputs retrieved 2026-11-08. OSM editor names, IDs and changeset metadata omitted from sports XML; geometries and tags retained.
The final mixed derived geometry contains OSM-derived content. Do not represent the whole package as MIT, CC0 or exclusively CC BY. Applicable ODbL database obligations and non-OSM layers must remain distinguished.

This minimal subset contains only XY footprint geometry, source record identifiers and attribution. Original EPSG:5179 geometry was transformed into WGS84 and clipped to [129.085,36.635,129.145,36.690]. All other research attributes are omitted. No endorsement is implied. The independent illustrative replacement mass rule is 6m; it is not a surveyed or research-estimated building height.

Terrain mesh is a modified approximately 30m digital surface model, smoothed/interpolated with approximate building pads, not a surveyed bare-earth model. Terrain colours are procedural and contain no imagery. No original raster is included.

Sentinel-derived water geometry: Contains modified Copernicus Sentinel data 2026.
Green/NIR bands from scene S2C_52SEF_20261030_0_L2A, acquired 2026-10-30T02:17:21.069Z and accessed 2026-11-03 through Element84 Earth Search/AWS, were used for an approximate NDWI water mask constrained by OSM river alignments. The resulting derived water geometry remains in this candidate. This is not a validated shoreline dataset. No original imagery or image texture is included.

Later designed/illustrative geometry: final evaluated geometry is included for technical reproducibility. No independent license grant to original software or architecture is made by this offer.
