Source offer for the Yeongyang illustrative model P01 used by 영양군 둘러보기앱 1.2.0.

The final-candidate-geometry-database.json.gz is the authoritative final GLB-decoded mesh database: objects, XYZ vertices, triangles, triangle material indices and material slot names. Coordinates are local EPSG:32652 metres with origin (510277.29590852157,4057439.6223628377), Blender Z-up. To recover UTM easting/northing add the origin. Z uses the approximate terrain datum described in transformation-spec.json. Web glTF uses (X,Z,-Y).

Independent replacement geometry inputs and precise current candidate transformation settings are supplied. Baseline OSM data and minimal research XY/source-ID records are separate layers. Later sports XML supplies OSM inputs for the stadium/courts. Object-source-id-index maps every final record to identifiable source records where available. The database decodes the published-candidate GLB exactly, preserving all triangle corners and assigning source objects by exporter membership and per-object/material triangle counts. Scalar appearance values and procedural terrain colour settings are supplied in appearance-materials.json; exact runtime heightfield and metadata files are also included. The final mesh database captures later alterations even where the earlier procedural editing chain has not been fully reconstructed.

This offer is not a claim that the full historical pipeline or every original evidence source has been recovered. Objects without source IDs and mixed-data licensing require review. No original scene, source archive, editable model, texture image or original software code is included. Original inferred research elevation attributes and their old audit arrays are omitted; legitimate mesh vertical coordinates and independent OSM tags remain.
