Modifications: original 3276 x 3276 resolution retained; JPEG recompressed at quality 86 with progressive encoding, without cropping or color adjustment.
Georeference: WGS 84 / UTM Zone 10N, EPSG:32610. Pixel spacing 30 m. RasterPixelIsPoint. Pixel (0,0) center: easting 504450 m, northing 4229850 m. Pixel (3275,3275) center: easting 602700 m, northing 4131600 m. Geographic corner centers approximately NW 38.216610 N, 122.949165 W; NE 38.210759 N, 121.826915 W; SW 37.331059 N, 122.949768 W; SE 37.325391 N, 121.840820 W.
At the modeled origin (38 N, 122 W), UTM position is approximately E 587798.417835 m, N 4206286.758159 m; image column 2778.280594, row 785.441395. Terrain mapping is an artistic local approximation; the campus architecture is modeled, not a representation of an actual campus at those coordinates.

Modifications: skin maps retained at 1024 px; hair/clothing maps at 512 px; eye maps at 256 px; brow/lash/teeth maps at 128 px. Opaque maps recompressed as JPEG quality 82 (normal maps quality 88), alpha maps as palette PNG. Geometry and animation compressed with EXT_meshopt_compression through glTF Transform 4.5.1; POSITION quantization uses 16 bits, retaining all vertices and topology. Skin, authored motion, materials and real-world scale are retained. Runtime requires the MIT-licensed Three.js Meshopt decoder.
